TABLE OF CONTENTS INDEX 1150 SECTION 1006 PORTLAND CEMENT CONCRETE : 1006- 1 General Requirements: Portland cement concrete shall consist of a mixture of hydraulic cement, fine aggregate, coarse aggregate, and water. It may also contain chemical admixtures, additives, and supplementary cementitious materials meeting the requirements herein. The contractor shall determine the mix proportions and shall furnish concrete which conforms to the requirements of the specifications. All concrete shall be sufficiently workable, at the slump proposed by the contractor within the specified range, to allow proper placement of the concrete without segregation, bleeding, or incomplete consolidation. It shall be the responsibi lity of the contractor to proportion, mix, place, finish, and cure the concrete properly in accordance with the requirements of the specifications. 1006- 2 Materials: 1006- 2.01 Cementitious M aterial:
Cementitious material is defined as an inorganic material or a mixture of inorganic materials that sets and develops strength by chemical reaction with water by formation of hydrates and is capable of doing so under water. In this specification, cementiti ous materials are defined as hydraulic cement (Portland cement or Portland- pozzolan cement) and supplementary cementitious materials (fly ash, natural pozzolan, or silica fume).
Hydraulic cement shall consist of either Portland cement or Portland- pozzolan cement. Portland cement shall conform to the requirements of ASTM C 150 for Type II, III, or V , and shall not contain more than 0.60 percent total equivalent alkalies. Portland- pozzolan cement shall conform to the requirements of ASTM C595 for blended hydraulic cement with moderate sulfate resistance, Type IP (MS). Cement of different types or brands shall not be intermingled or used in the same batch. The contractor shall provide suitable means for storing and protecting the cement against dampness. Cement which has become partially set or which contains caked lumps shall not be used. TABLE OF CONTENTS INDEX 1151 The use of either sacked cement or bulk cement is permissible. The use of fractional bags of sacked cement will not be permitted unless the contractor elects to weigh the cement into each batch.
Supplementary cementitious materials may be used in addition to hydraulic cement. Supplementary cementitious materials shall be approved prior to their use. When either moderate or high sulfate resistant concrete is specified in the Special Provisions, the proposed hydraulic cement/supplementary cementitious material blend shall be tested for sulfate expansion in accordance with ASTM C1012. When moderate sulfate resistance is specified, the maximum expansion shall be 0.10 percent at six months. When high sulfate resistance is specified, the maximum expansion shall be 0.05 percent at six months or 0.10 percent at one year.
Fly ash and natural pozzolan shall conform to the requirements of ASTM C618 for Class C, F, or N, except that the loss on ignition for Class F and Class C shall not exceed 3 percent.
Silica fume shall conform to the requirements of ASTM C1240. Certification of silica fume will be based on a Cert ificate of Compliance conforming to the requirements of Subsection 106.05 of the specifications submitted for each lot of silica fume.
The certification and acceptance of cementitious materials will be on the basis of the materials originating from an Approved Materials Source. Approved Materials Sources Lists for cementitious materials are maintained by the ADOT Materials Group, Structural Materials Testing Section. Source approval of hydraulic cement, fly ash, and natural pozzolan producers/suppliers will be based on monthly submittals to the ADOT Materials Group, Structural Materials Testing Engineer, at cert@azdot.gov. The following documentation shall be submitted:
during that month; and TABLE OF CONTENTS INDEX 1152
the corresponding Certificate of Compliance for that month. 1006- 2.02 Water: Water shall meet the requirements of ASTM C1602, except that it shall contain no more than 1,000 parts per million of chlorides as Cl and no more than 1,000 parts per million of sulfates as SO4. The water used shall be free of injurious amounts of oil, acid, alkali, clay, vegetable matter, silt, or other harmful matter. Potable water obtained from public utility distribution lines will be acceptable. 1006- 2.03 Aggregates:
When concrete is to be placed at elevations above 4,500 feet, the fine aggregate and the coarse aggregate shall be subjected to five cycles of the sodium sulfate soundness test, and the weighted percentage loss determined separately for each, in accordance with the requirements of ASTM C88. The weighted percentage loss determined for each shall not exceed 10 percent . Tests for soundness may be waived when aggregates from the same source have been approved and the approved test results apply to the current production from that source. Mill tailings or material from mine dumps shall not be used in the production of fine or coarse aggregate. The following test methods may be used to evaluate the quality of aggregates for concrete: TABLE 1006 -1 Test Methods for Quality of Aggregates Sampling Arizona Test Method 105 Reducing field samples to testing size AASHTO R 76 Potential for Alkali Silica Reaction

When multiple sources of material are used under one product code, documentati on shall be provided which shows similar performance using materials from each source. Multiple sources of material shall be listed on the mix design as alternative sources. 1006- 3.03 Approval of Concrete Mix Designs: All mix designs shall be approved by t he Engineer prior to use. All mix designs for precast or prestressed concrete shall be approved by the Materials Structural Testing Section prior to use. Mix designs meeting the criteria herein and identified as one of the following will be considered for approval: A mix design that has been previously approved or used successfully on an ADOT project within the past 24 months and is on file with the Department. A mix design similar to that specified that has been used successfully on a non- ADOT project and sufficient mix history no older than 24 months shall be included with the mix design submittal. The mix history shall include dates placed, compressive strength test records, and other pertinent data. A new mix design that does not meet the criteria for a previously used mix design requires a trial batch from either the field batch plant or an ADOT approved testing laboratory. In no case shall the approval of a mix design relieve the contractor of the responsibility for the results obtained by the use of such approved mix design.
Mixtures having been ADOT approved or used previously with satisfactory compressive strength history within the past 24 months may be acceptable provided all of the following apply:
changed, and the water -cementitious materials ratio has not increased; TABLE OF CONTENTS INDEX 1163
remain unchanged and the total coarse aggregate quantity has not changed by more than 5 percent ;
changed by more than 2 percent ;
2 percent ;
been measured an d updated within the last 12 months; and
When submitting a concrete mix used successfully on a non- ADOT project, mix history shall be required for consideration and approval of the mix. Using strength test records from an ADOT approved laboratory, which are not more than 24 months old, a sample standard deviation (ss) may be used to establish the required over -design. Test records shall comply with the following criteria:
procedures, and conditions similar to those expected on the project ;
compressive strength, or strengths, within 1000 pounds per square inch below or 1000 pounds per square inch above the specified design compressive strength;
air content (when applicable), and calculated results from Table 1006- 6 and Table 1006- 7; and
strength tests that span a period of not less than 45 days. If the test record consists of at least 30 consecutive tests, the sample standard deviation (ss) of those tests is used. If the test record consists of 15 to 29 consecutive tests, the standard deviation of TABLE OF CONTENTS INDEX 1164 those tests shall be modified in accordance with Table 1006- 6. TABLE 1006 -6 Standard Deviation Modification Factor No. of tests * Modification factor for sample standard deviation (k) < 15 Minimum 20% over -design 15 1.16 20 1.08 25 1.03 30 or more 1.00 Note:
* For 15 to 29 tests, interpolate for intermediate number of tests. k = Modification factor (multiplier) by which ss shall be multiplied to be used to determine the required minimum over -design compressive strength, f 'cr, in Table 1006 -7. The required minimum over -design compressive strength shall be determined by the equations shown in Table 1006- 7. Table 1006 -7 Over -Design Compressive Strength Equations Specified design compressive strength, psi Required minimum over design compressive strength, psi f 'c ≤ 5000 Use the larger value computed from these two equations:
f 'cr = f 'c + 1.34k × s s f 'cr = f 'c + 2.33k × s s - 500 f 'c > 5000 Use the larger value computed from these two equations:
f 'cr = f 'c + 1.34k × s s f 'cr = 0.90 f 'c + 2.33k × s s Legend: f 'c= Specified design compressive strength. f’cr= Required minimum over -design compressive strength ss= Sample standard deviation k= Modification factor from Table 1006 -6 if applicable
To be considered for approval by the Engineer, the average strength of the provided test data shall be greater than f’cr, and the mix history shall be from a mix deemed to be sufficiently representative of the materials and proportions proposed for use in the submitted mix design. TABLE OF CONTENTS INDEX 1165
The over -design requirement for new mix designs shall be a minimum of 20 percent of the specified design compressive strength and shall be substantiated by trial batches. Trial batch results may be from laboratory trial batches or full -scale trial batches.

The Engineer reserves the right to witness the full -scale trial batch activities.
be observed, tested, and documented by the ADOT Materials Structural Testing Section and approved by the Engineer. Trial batches shall have slump results within the range specified for the proposed work. When air -entrai ned concrete is specified, the air content shall be in compliance with the specified requirements. Compressive strength testing samples shall be cured and tested by an ADOT Approved Laboratory. Trial batch test results, prior to the specified compressive strength acceptance age, may be used for early approval if the compressive strength test results meet the minimum over -design requirement for the specified acceptance age. When approved by the Engineer, concrete from trial batches may be used in the work at locations where concrete of a lower strength is required and such concrete shall meet the requirements of the class of concrete at that location. 1006- 4 Concrete Production: 1006- 4.01 General Requirements: The contractor may obtain concrete for each class of concrete and for each strength of ClassS concrete from a source approved by the Engineer in lieu of establishing a batch plant at the project site. TABLE OF CONTENTS INDEX 1166 1006- 4.02 Measuring Materials:
Cementitious material shall be measured by weight. When supplementary cementitious materials are used in the concrete mixtures, the cumulative weight is permitted to be measured with hydraulic cement, and on a scale which is separate and distinct from those used for other materials. The weight of the hydraulic cement shall be measured before supplementary cementitious materials. When the quantity of cementitious material exceeds 30 percent of the full capacity of the scale, the measured quantity of the hydr aulic cement shall be within 1 percent of the required weight, and the cumulative measured quantity of hydraulic cement plus supplementary cementitious materials shall also be within 1 percent of the required cumulative weight at each intermediate weighing . For smaller batches of less than 30 percent of the full capacity of the scale, the measured quantity of the hydraulic cement and the measured cumulative quantity of hydraulic cement plus supplementary cementitious materials used shall not be less than the required amount or more than 4 percent in excess of the required amount. In specific cases, cementitious materials in bags may be used with prior approval of the Engineer.
Mixing water is defined as the total amount of water in a batch less the water absorbed by the aggregates and is used to calculate the w ater - cementitious materials ratio (w/cm). Mixing water shall consist of batch water (water weighed or metered at the plant), ice, free moisture on the aggregates, wash water retained in the mixer before batching, and water added at the jobsite in accordance with Subsection 1006- 7.03 of the specifications. The batch water shall be measured by mass or volume to an accuracy of ± 1.5 percent of the target batch water. If the quantity of water introduced from admixtures increases the water -cementitious materials ratio by more than 0.01, it shall also be included in the total amount of mixing water. In the case of truck mixers, any wash water retained in the drum for use in the next batch of concrete shall be measured; if this proves im practical the wash water shall be discharged before loading the next batch of concrete. The total quantity of mixing water shall not exceed the mix design target quantity by more than 3 percent.
Aggregate shall be measured by weight. The quantity of aggregate weighed shall be the required dry weight plus the total moisture content (absorbed and surface) of the aggregate. When aggregates are measured in an individual or cumulative weigh batcher and the required weight of aggregate is equal to or greater than 30 percent of the scale capacity, the total quantity of aggregate shall be within 2 percent of the required weight. In addition, if a cumulative weigh TABLE OF CONTENTS INDEX 1167 batcher is used, the quantity of aggregate at each successive weighing shall be within 2 percent of the required weight. When aggregates are measured in individual or cumulative weigh batchers, and the required intermediate or final weight is less than 30 percent of the scale capacity, the aggregate weight shall be within 3 percent of the required weight.
Chemical admixtures in powdered form or other additives in solid form (such as fibers or color) shall be measured by weight. Liquid chemical admixtures shall be batched by weight or volume. Admixtures measured by either weight or volume, shall be batched with an accuracy of ± 3 percent of the total required amount. For liquid chemical admixtures, dispensers of a mechanical type capable of adjustment for variation of dosage, and of simple calibration, are req uired, unless approved by the Engineer. 1006- 4.03 Batching of Concrete :
Concrete may be batched in a standard batch plant or a central mixing plant. The plant may be situated at the project site, or it may be located off-site or at a commercial supplier. All materials utilized in the batching of concrete shall be from an approved source or supplier.
The handling and storage of concrete aggregate shall be such as to maintain them at or above a saturated- surface- dry (SSD) moisture condition and to minimize segregation or the intermixing and contamination with foreign materials. The Engineer may require that aggregate be stored separately. Different sizes of aggregate shall be separated by bulkheads or stored in separate stockpiles sufficiently removed from each other to prevent the materials from becoming intermixed. When aggregates are stored on the ground, the sites for the stockpiles shall be level and clear of all vegetation. The bottom 1 foot layer of aggregate shall not be disturbed or used. All concrete batch plants and batching operations shall have been inspected and satisfy applicable criteria before being used to produce concrete. As an alternative to an ADOT inspection of the concrete batch plants and batching operations, the supplier may submit certification of their concrete production facilities from NRMCA or Arizona Rock Products Association (ARPA) to the Engineer. Concrete batch plants shall be inspected a minimum of once every two years. ADOT may inspect concrete batch plants at any time. TABLE OF CONTENTS INDEX SECTION 1006 1168 Each batch plant shall be equipped to control the time when the water enters the mixer during the mixing cycle. Batch and mixing time shall be calculated from the time cementitious material is first combined with water or aggregates.
The handling and storage of concrete aggregate for Class P concrete at the job site or a project specific plant site shall be such as to minimize segregation. Stockpiles shall be neat and regular in form and shall occupy as small an area as possible. Contamination of concrete aggregate for Class P concrete by contact with the ground at the job site shall be prevented. The contractor shall take the necessary measures to prevent such contamination. Such preventive measures include placing aggregate on hardened surfaces consisting of Portland cement concrete, asphaltic concrete, or cement treated material. The contractor shall maintain at least two full days’ worth of production of fine and coarse aggregate stockpiled at the batch plant for Class P concrete prior to starting and throughout the duration of Portland cement concret e paving operations. This requirement is waived for the last two days of production.
Concrete batch plants shall be operated in accordance with the manufacturer’s guidelines and recommendations. The amount of material measured for each batch of concrete shall not exceed the plant’s rated capacity. A record of certification current to within the last six months for all scales, balances, load cells, or water measuring systems used in the production of concrete shall be maintained at the batch plant and shall be made available to the Engineer upon request. When requested by the Engineer, the contractor shall supply a separate record for each batch of concrete which shows the batch weight or quantity of each individual ingredient. The amount of water introduced into the batch including that contained on the aggregate shall be verifiable.
For each class of concrete and each strength of ClassS concrete, except for Class P concrete produced in a batch plant at the project site and used exclusively for Class P work, the contractor shall furnish a delivery ticket for each batch of concrete, including any trial batches. The minimum information to be shown on each delivery ticket shall be:
TABLE OF CONTENTS INDEX 1169
design water -cem entitious material ratio Any manually added additives or admixtures previously approved by the Engineer to be added to an existing mix design, which cannot go through the plant or batching system, shall be recorded and shown on the delivery ticket. In addition, the number of revolutions that the concrete has been mixed at mixing speed in a truck mixer shall be noted on the delivery ticket. An authorized representative of the contractor shall be responsible for each delivery ticket and shall sign each deli very ticket accepting the contractor's responsibility for the concrete. The representative shall furnish a copy of the delivery ticket to the Engineer after discharge of the concrete is complete. 1006- 4.04 Mixing and Transport of Concrete :
All concrete shall be homogeneous and thoroughly mixed, and there shall be no lumps or evidence of un- dispersed cement. Equipment having components made of aluminum or magnesium alloys, which would have contact with plastic concrete during mixing and transporting, shall not be used.
Drum Mix Plant): The volume of concrete mixed per batch shall not exceed the capacity of the mixer as shown on the manufacturer's plate or documentation. No spillage of concrete is allowed during the pro cess of mixing. While mixing, the mixer shall be operated at the speed shown on the manufacturer's plate as the mixing speed. The mixing time shall not be less than 60 seconds per batch for Class P concrete and the mixing time shall be increased if directed by the Engineer. The mixing time shall be not less than 60 seconds for 1 cubic yard and shall be increased 15 seconds for each additional cubic yard or fraction thereof for ClassS or Class B concrete. The mixer shall have an automatic timing device whi ch locks the discharge equipment until the required mixing time has been completed. TABLE OF CONTENTS INDEX 1170 The mixer shall be operating at mixing speed at the time that all ingredients enter the mixer to ensure the immediate beginning of the mixing cycle. Mixing time shall end when the discharge chute opens. The contents of the mixer shall be completely discharged before the succeeding batch is placed in the mixer. Any concrete discharged before the mixing time is completed shall be disposed of by the contractor at no additional cost to the Department. Central mixers shall be equipped with automatic batch meters for counting the batches for Class P concrete. The contractor shall furnish the batch count daily to the Engineer. In the case of mixing in a central mixer, when fibers are incorporated into the concrete, mixing time and revolution rate is performed the same way as plain concrete because there is sufficient shear provided to uniformly disperse the fibers. A test or trial mixing is always recommended to ensure that the m ixture supports the fiber type and dosage and that there are no problems with the batching sequence. Mixed concrete shall be transported in truck mixers, truck agitators or in non- agitating trucks. When truck mixers or truck agitators are used, the concret e shall be continuously agitated from the time of loading until the time of discharge. Agitation shall be by rotation of the drum at the speed shown on the manufacturer's plate as agitating speed. The truck mixer or truck agitator shall be loaded and operated within a capacity not to exceed 80 percent of the gross volume of the drum. The rate of discharge shall be controlled by the speed of rotation of the drum in the discharge direction with the discharge gate fully opened. Bodies of non- agitating trucks shall be smooth, mortar -tight, metal containers and shall be capable of discharging the concrete at a satisfactory controlled rate without segregation. If discharge of concrete is accomplished by tilting the body, the surface of the load shall be retarded by a suitable baffle. Covers shall be provided when needed for protection. Discharge from non- agitating trucks shall be completed within 45 minutes from the time concrete is batched. Concrete hauled in open -top vehicles shall be protected against rain. When the ambient temperature exceeds 85 degrees F the concrete shall be covered if it could be exposed to the sun for more than 30 minutes.
All concrete truck mixers shall be inspected and satisfy applicable criteria before being used to mix and deliver concrete. As an alternative to the annual ADOT inspection of truck mixers, the trucks may be TABLE OF CONTENTS INDEX 1171 inspected in accordance with the requirements of the NRMCA and/or ARPA inspection programs. Such inspections shall be performed in accordance with NRMCA’s “Section 5 of Quality Control Manual, Section 3, Inspection & Certification of Delivery Vehicles” or ARPA’s “Certification of Ready Mixed Delivery Fleet” checklist and guideline. Upon satisfactory completion of inspection, an inspection sti cker shall be applied in a clearly visible location to the inside of the driver’s side door of the truck, or an NRMCA card shall be readily available. Truck mixers that do not have a valid NRMCA card, or ADOT or ARPA sticker indicating the date of inspecti on are not allowed to supply concrete to ADOT projects. Truck mixers shall be inspected annually at a minimum and may be inspected at any time. Each mixer shall meet the specified requirements for type and size and shall have attached in a prominent place a manufacturer's plate showing the gross volume of the mixer and the recommended speeds of the mixer for mixing and for agitating. Truck mixers shall be operated within a capacity not to exceed 63 percent of the gross volume of the drum and at speeds show n on the manufacturer's plate as mixing and agitating speeds. Truck mixers shall be equipped with an electrically or mechanically activated revolution counter by which the number of drum revolutions may be verified. The counter shall accurately register the number of revolutions. It shall be mounted on the truck mixer or inside the truck cab, so that it may be safely and conveniently read. The revolution counter shall be reset to zero after all materials have been loaded into the drum at the plant. Truck- mixed concrete shall be mixed entirely in the truck mixer. Mixing shall begin after the cement has been combined with either the aggregate or water. Each batch of concrete shall be mixed for not less than 70 nor more than 100 revolutions of the drum, at m ixing speed, after all materials have been loaded into the drum at the plant, except that when approved by the Engineer, the maximum of 100 revolutions may be increased. Any revolving of the drum beyond the maximum number of revolutions shall be at the agi tating speed. When fibers are incorporated into the concrete, it is recommended to add the fibers in a continuous manner. A mixing speed of 10 to 12 rpm is typically used for the rate of addition in trucks. A minimum of 40 revolutions (four to five minutes) after all the fibers are added is recommended for proper mixing and dispersion of fibers in trucks. Mixers shall be cleaned at suitable intervals. Water used for cleaning the mixer shall be discharged prior to further batching.
Concrete mixing in volumetric mixers for ClassS or Class B concrete shall be performed in accordance with the requirements of ASTM C685. TABLE OF CONTENTS INDEX 1172 1006- 4.05 Manufacturing Precast Items:

The rate of concrete placement and consolidation shall be such that the formation of cold joints within monolithic sections of any bridge member shall not occur, but at no time shall concrete placement be less than 25 cubic yards per hour. When consolidating concrete that includes epoxy coated reinforcement which requires vibration during placement, methods of vibration shall be equipped with neoprene or rubber boots or like material that protects the epoxy coatings from damage and/or abrasion. TABLE OF CONTENTS INDEX 1176 When concrete placement is interrupted by rain, the forms shall be covered with tarps or plastic. If it is determined that concrete placement can proceed during rain, tarps or plastic shall be used to cover the forms ahead of and behind the concrete placement.
Calibration reports for batch plant scales and measuring devices shall be supplied to the Structural Materials Testing Section when requested. Each precast plant shall submit a “Hot Weather” and/or a “Cold Weather” concrete batching and placement plan which addresses the steps that will be taken to ensure concrete temperature and curing meets the specifications. The plan shall specify procedures detailing how the concrete temperature will be monitored throughout each day’s production. The Structural Materials Testing Section may test concrete temperature at any time. Concrete failing to meet the specification will be rejected along with any precast products produced that day. The precast manufacturer shall supply annual test results for aggregate as required per ASTM C33, and also an annual absorption test on manufactured products. All concrete batched at the manufact urer’s plant, or purchased from a ready mix supplier, shall be batched with load cell indicating devices providing a digital readout and printed weights. Copies shall be available when requested by the Structural Materials Testing Section. The rate of concrete placement and consolidation shall be such that the formation of cold joints within monolithic sections will not occur. When consolidating concrete that includes epoxy coated reinforcement which requires vibration during placement, methods of vibratio n shall be equipped with neoprene or rubber boots or like material that protects the epoxy coatings from damage and/or abrasion. When a stripping strength is specified, the manufacturer may determine the concrete strength using Arizona Test Method 318, “Estimating the Development of Concrete Strength by Maturity Method.” When concrete placement is interrupted by rain, the forms shall be covered with tarps or plastic. If it is determined that concrete placement can proceed during rain, tarps or plastic shall be used to cover the forms ahead of and behind the concrete placement.
SCC shall be flowable under its own weight and completely fill the formwork, even in the presence of dense reinforcement, without the ne ed of any vibration, while maintaining homogeneity. Placement is to be accomplished in one lift, with the placement equipment within 25 feet of the rolling edge that the SCC creates. TABLE OF CONTENTS INDEX 1177 Trial mixes shall be observed by an ADOT representative. Trial mixes may include an inverted slump spread test in accordance with ASTM C1611, L- box, J- box, J- ring, Column Segregation Test, or other tests as deemed necessary by the Engineer for the concrete mix approval. In addition, the following is required:
for each precast concrete product being produced;
identified for the mixture; and
spread defined in the mix design. Concrete strength test cylinders shall be fabricated in accordance with ASTM C31, but filling the molds shall be done in accordance with ASTM C1758. Concrete unit weight and air content tests shall be performed in accordance with ASTM C138 and ASTM C231, respectively, but filling the cylinder molds shall be done in accordance with ASTM C1758. 1006- 5 Weather and Placement Limitations: 1006- 5.01 General Requirements: Concrete shall not be placed during adverse conditions, which may include but are not limited to rain, snow, freezing weather, unstable site conditions, excessively high ambient temperature, and high winds, unless approved by the Engineer. Under rainy conditions, placing of concrete shall be stopped before the quantity of surface water is sufficient to cause a flow or wash of the concrete surface or have a detrimental effect on the finished concrete and acceptance parameters. Placing of concrete shall immediately cease if the hauling vehicles or any equipment or pedestrian traffic tracks mud on the prepared base or changes the allowable subgrade dimensional tolerances for Class P concrete and slabs placed on subgrade for ClassS or Class B concrete. 1006- 5.02 Hot Weather Concreting: Forms, subgrade, and reinforcing steel shall be lightly sprinkled with cool water just prior to the placement of concrete. TABLE OF CONTENTS INDEX 1178 Chilled mix water or well crushed ice (substituted as a part of the mix water on a pound for pound basis) may be used to control the concrete temperature. Aggregate may be cooled by systematic sprinkling of aggregate stockpiles for evaporative cooling or by the use of liquid nitrogen systems. If required by the Engineer, windscreens shall be used to reduce the evaporation rate when curing methods alone are not sufficient to maintain the evaporation rate within acceptable limits. On bridge decks, windscreens shall project at least 6 feet above the prepared bridge deck surface. Windscreens may be made of any construction material that provides sufficient st rength to resist the force of the wind. If during finishing an unexpected environmental change or delay occurs, a monomolecular film product that aids in retarding the evaporation may be used prior to finishing with the Engineer’s approval. The monomolecular film shall be applied in accordance with the manufacturer’s recommendations. The evaporation retarder shall be applied in a fine mist using suitable sprayers; it shall not impact the plastic concrete surfaces in a stream. Concrete surfaces to which an evaporative retardant has been applied shall not be subjected to finishing which mixes the retardant into the plastic concrete. Application of an evaporation retardant shall not delay the placement of curing compound as described in Subsection 1006- 6.01( C) of the specifications. 1006- 5.03 Cold Weather Concreting: Concrete shall not be placed on or against ice- coated forms, reinforcing steel, structural steel, conduits, or construction joints; nor on or against snow, ice, or frozen earth materials. Immediately prior to placing concrete, the temperature of forms, reinforcing steel, earthen material, or any other material that will come in contact with the freshly placed concrete shall be a minimum temperature of 40 degrees F. If artificial heat is used to adjust the temperature of the items that will com e in contact with the freshly mixed concrete, the temperature of these items shall not exceed 10 degrees F greater than that of the concrete being placed. Concrete operations shall be discontinued when a descending ambient temperature in the shade and away from artificial heat falls below 40 degrees F. Concrete operations shall not be resumed until an ascending ambient temperature in the shade and away from artificial heat exceeds 35 degrees F unless otherwise approved by the Engi neer. Mixing and placing concrete shall continue no later than that time of day which allows sufficient time to place and protect the concrete already poured before the ambient temperature drops to 35 degrees F. TABLE OF CONTENTS INDEX 1179 Concrete shall be protected in a manner to maintain all concrete surface temperatures at not less than 50 degrees F for a period of 72 hours after placement and at not less than 40 degrees F for an additional 96 hours. The contractor may use equipment to heat the aggregates or water, or both, prior to mixing. If aggregates are heated, the minimum temperature of the heated aggregate shall be 60 degrees F and the aggregates shall have no chunks of ice or frozen aggregate present. Equipment used to heat the aggregates shall be such that consistent temperatures are obtained throughout the aggregate within each batch and from one batch to another. Water shall not be heated in excess of 150 degrees F unless the water is mixed with the aggregate prior to the addition of cement to the batch. During the heating or mixing process, cement shall not be added to water and aggregate combinations which exceed 100 degrees F. When weather forecasts indicate a probability that ambient temperatures are to fall below 35 degrees F during the placement or curing periods, the contractor shall submit a cold weather concreting plan to the Engineer for approval prior to concrete placement. The cold weather concreting plan shall detail methods and equipment which are to be used to ensure that the required concrete temperatures are maintained. The contractor shall provide adequate cold weather protection in the form of insulation and/or heated enclosures to protect the concrete after placement. For bridge decks and suspended structures, the cold weather concreting plan shall include protection measures for both the top and bottom surfaces of the concrete. This protection shall maintain concrete surface temperatures as specified above at all locations in the structure. When artif icial heating is required, the heating units shall not locally heat or dry the surface of the concrete. When a cold weather concreting plan is required, the Engineer may require concrete temperatures to be measured and continuously recorded by the use of t emperature sensing devices during the entire curing period. The contractor shall provide the temperature sensing devices, including its manufacturer’s certification which shall be in accordance with ASTM C1074, and recording instruments. The contractor shall install temperature sensing devices near the surface of the concrete at locations and depths designated by the Engineer. When concrete is placed on a bridge deck or suspended structure, both the bottom surface and the top surface shall be monitored with temperature sensing devices. Temperature sensing devices and recording instruments shall be approved by the Engineer. The contractor shall continuously monitor the concrete temperature and provide the recorded data to the Engineer upon request. If the surface concrete temperature at any location in the structure falls below 35 degrees F during the curing period, the Engineer may direct the contractor to core the areas in question at the locations indicated by the Engineer. The contractor shalls ubmit the cores to a petrographer for examination in accordance with ASTM C856. Concrete damaged by frost, as determined by the petrographer, shall be removed and replaced TABLE OF CONTENTS INDEX 1180 at no additional cost to the Department. All costs associated with coring, transmi ttal of cores, and petrographic examination shall be at no additional cost to the Department regardless of the outcome of the petrographic examination. The placing of concrete will not be permitted until the Engineer is satisfied that all the necessary protection equipment and materials are on hand at the site and in satisfactory working condition. Concrete requiring cold weather protection shall have such protection removed at the end of the required curing period in such a manner that will permit a gradual drop in the concrete temperatures . 1006- 6 Curing Concrete: 1006- 6.01 Curing Cast -in-Place Concrete:
All cast -in-place concrete shall be cured by one, or by a combination of more than one, of the methods specified herein and curing shall begin immediately after completion of machine or hand finishing of the fresh concrete. Curing shall be continued for a period of at least seven days after placing if ei ther Type II Portland cement or Portland pozzolan cement has been used, or for at least three days if Type III Portland cement has been used. Surfaces requiring a Class II finish shall not be cured by the Liquid- Membrane Forming Compound Method until after the finishing operations are completed. No traffic, hauling, storing of material or other work shall be allowed on any concrete surface during the required curing periods.
All surfaces not covered by reasonably waterproof forms shall be kept damp by applying water with a nozzle that so atomizes the flow of the water that a fog mist and not a spray is formed until the surface of the concrete is covered with a curing medium or sprinkling of the surface is permitted. The moisture from the nozzle shall not be applied under pressure directly upon the concrete and shall not be allowed to accumulate on the concrete in a quantity sufficient to cause a flow or wash the surface. If a curing medium is used, the concrete shall be kept continuously wet by sprinkling with water for the entire curing period. Burlap, rugs, carpets, or earth or sand blankets may be used as a curing medium to TABLE OF CONTENTS INDEX 1181 retain the moisture during the curing period. Application of the curing medium shall not begin until such time that placement can be made without marring the surfaces of the concrete. Application of a non- atomized spray of water, water by brushes, or any other non -approved method will not be permitted. Fogging equipment shall consist of a mechanically operated pressurized system using incrementally spaced triple headed nozzles or equivalents. The nozzles shall be pointing horizontally, parallel to the surface of the concrete and at a distance not to exceed 36 inches above the concrete surface. The fogging equipment shall be mounted such that it is stationary. Each nozzle shall be equipped with an easily accessible control capable of varying the volume of water flow and immediately shutting off the water when in the off position. Hand- held fogging equipment will not be allowed. If a curing medium is not used, the entire surface of the concrete shall be kept damp by the application of water with an atomizing nozzle as specified above until the concrete has set, after which the entire surface of the concrete shall be sprinkled continuously with water for the entire curing period. In no case shall curing be interrupted by more than one hour during the curing period.
Liquid membrane forming compound shall conform to the requirements of ASTM C309 and also meet the criteria in Table 1006- 8. Approval of curing compound will be based on a C ertificate of Analysis conforming to the requirements of Subsection 106.05 of the specifications submitted for each lot. Curing compound shall not be used on a project prior to approval. Any curing compounds not previously approved for use on a current or past ADOT project shall be tested for pre- approval by the Structural Materials Testing Section prior to the submittal of the Certificate of Analysis. The pre- approval testing shall be determined by the Engineer and in accordance with the requirements in T able 1006- 8. The approval of Type 2 (white pigmented) curing compounds shall be effective for a maximum of six months from the production date. The approval of Type 1- D (clear or translucent with fugitive dye) curing compounds shall be effective for a maxi mum of 12 months from the production date. TABLE OF CONTENTS INDEX 1182 TABLE 1006 -8 Testing Criteria for Liquid Membrane Forming Compound Procedure Criteria Color Clear (Type 1 -D) White (Type 2) Deleterious Reaction w/ Concrete No Reaction No Reaction Drying Time Test Less than 4 hours Less than 4 hours Moisture Loss (72 hours) Less than 0.55 kg/m² Less than 0.55 kg/m² Reflectance Test N/A 60% or greater Three -Day Settlement Test (MNDOT Procedure) Less than 2 ml after 3 days Less than 2 ml after 3 days Non -volatile Content Test (D2369 Method A) Minimum 25% Minimum 25%
The Engineer shall reserve the right to sample curing compound at the source to perform tests specified in ASTM C309 for verification purposes. Sampling frequency will be at the discreti on of the Engineer. Curing compound with failing verification test results shall not be used. All surfaces not covered by waterproof forms shall be cured by the liquid- membrane forming compound method. The curing compound shall be applied to t he concrete immediately following the surface finishing operation in one or more applications totaling a rate of at least 1 gallon per 100 square feet. The contractor shall not exceed the coverage rate specified in ASTM C309. The curing compound shall form a continuous unbroken surface. Type 2 compound with either a Class A or Class B vehicle shall be used for concrete pavement, bridge decks, and approach slabs. Type 1- D compound with either a Class A or Class B vehicle shall be used for other concrete items. If the membrane film is broken during the curing period, the broken area shall be given a new application of compound at a rate sufficient to ensure uniform coverage. In no case shall curing be interrupted by more than one hour during the curing period.
Formed surfaces of concrete may be cured by retaining the forms in place. The forms shall remain in place for the entire curing period. All joints in the forms and the joints between the end of forms and concrete shall be kept moisture- tight during the curing period. Cracks in the forms and cracks between the forms and the concrete shall be resealed by methods approved by the Engineer. TABLE OF CONTENTS INDEX 1183
Slabs: The top surface of bridge decks, approach slabs, and anchor slabs shall be cured by the liquid- membrane forming compound method and by the water curing method. The curing compound shall be applied progressively immediately following the surface finishing operation. Water curing shall be applied not later than four hours after the completion of the surface finishing operations and shall be applied as specified herein. The top surface of bridge decks, approach slabs, and anchor slabs that will be covered with a special riding surface or waterproofing membrane shall be cured by the water curing method only. Water curing shall be applied progressively immediately following the surface finishing operation as specified herein. 1006- 6.02 Curing Precast Concrete:
The contractor may cure precast concrete in accordance with the requirements specified above for curing cast -in-place concrete or the curing of precast concrete may be performed by external heating. This may be accomplished by the use of low -pressure steam or radiant heat with moisture. If curing of the concrete is accomplished by low -pressure steam or radiant heat with moisture, curing will be considered completed after termination of steam or radiant heat curing. Rapid t emperature changes in the concrete shall be avoided during the cooling period. If curing of the concrete is accomplished by the water curing method, the liquid -membrane forming compound method, or the forms- in-place method, such curing shall be continued f or a period of at least seven days after placement of the concrete. The curing time may be reduced to a minimum of three days when a Type III Portland cement has been used. For precast items, when a concrete mix contains silica fume, a curing plan accepta ble to the Engineer shall be submitted for approval. Concrete test cylinders shall be initially cured with, and in the same manner as the precast concrete products. Final curing will be per AASHTO T 23/ASTM C31. TABLE OF CONTENTS INDEX 1184
After placement of the concrete, precast items shall be held for a minimum two -hour presteaming period. If the ambient air temperature is below 50 degrees F, steam shall be applied during the presteaming period to hold the air surrounding the precast item at a temperature between 50 and 90 degrees F. When the ambient temperature falls below 50 degrees F, steam or radiant heat may be used to keep the enclosure at a temperature of not m ore than 90 degrees F until the accelerated curing period begins. Accelerated curing shall not commence until one hour after initial set or three hours after placement of concrete, whichever is longer. Initial set will be determined in accordance with AST M C403 and the results submitted with each mix design. To prevent moisture loss on exposed surfaces during the presteaming period, precast items shall be covered as soon as possible after casting or the exposed surfaces shall be kept wet by fog spray or wet blankets. Enclosures for steam curing shall allow free circulation of steam about the member and shall be constructed to contain the live steam with a minimum moisture loss. The use of tarpaulins or similar flexible covers will be permitted, provided they are kept in good repair and secured in such a manner to prevent the loss of steam and moisture. Steam at the jets shall be low pressure and in a saturated condition. Steam jets shall not impinge directly on the concrete, test cylinders or forms. During application of the steam, the ambient air temperature rise within the enclosure shall not exceed 40 degrees F per hour. The average curing temperature throughout the enclosure shall not exceed 160 degrees F and shall be maintained at a constant level for a sufficient length of time so as to ensure the development of the required compressive strength by the ag e of 28 days in concrete items which are not be prestressed. The concrete temperature during accelerated curing shall not exceed 170 degrees F. The manufacturer shall have a temperature measuring device(s) that allows the Department to monitor the concrete curing temperature at all times. For items which are to be prestressed, the constant temperature shall be maintained for sufficient time necessary to develop the concrete compressive strength required for prestressing. The ambient curing temperature shall not exceed 175 degrees F at any point. Control cylinders shall be covered to prevent moisture loss and shall be placed in a location where temperature is representative of the average temperature of the enclosure. Temperature recording devices that w ill provide an accurate continuous permanent record of the ambient curing temperature shall be provided. A minimum of two temperature recording devices or one for every 200 feet of continuous bed length are required for checking temperature. The location of each temperature measuring device will be chosen by the Engineer. The enclosure around each precast concrete item shall be TABLE OF CONTENTS INDEX 1185 adequate to ensure a consistent concrete curing temperature. Once the curing enclosure procedure is established, the concr ete curing temperature shall be monitored at one location for each precast item. A temperature measuring device shall be placed in each precast bridge member. The difference in the concrete curing temperature at the ends of each precast bridge member shall not exceed 20 degrees F. Forms shall not be considered a component of the enclosure during accelerated curing. A temperature measuring device shall be placed in at least two precast concrete products. The difference in the concrete curing temperature at any location within the enclosure for a precast concrete product shall not exceed 20 degrees F. When box girders or voided slab lengths are less than 60 feet, the concrete curing temperature shall be measured on every other bridge member. The manufacturer shall supply a report of the concrete curing temperatures for each concrete casting. In the event the side forms are removed before the precast unit has attained the required release compressive strength, the curing method shall be continuous in maintai ning the temperature and moisture level as described above, within the enclosure, as nearly as practical. There shall not be a delay in re- covering the girder or prestress member.
Radiant heat shall be applied by means of pipes circulating steam, hot oil or hot water, or by heating elements or electric blankets on the forms. Pipes, blankets or elements shall not be in contact with the concrete surfaces. Moisture shall be applied in such a manner as to keep the top surface of the precast unit continuously moist during the curing period by fogging or spraying. Moisture shall be maintained by a cover of burlap or cotton matting and further covered by a waterproof tarpaulin with an insulating cover. Temperature limits and the use of recording thermometers shall be the same as curing with low -pressure steam. Application of the heat cycle may be accelerated to meet climatic conditions upon the approval of the Engineer. A temperature sensing device shall be placed 2 ± 1/2 inches from the heated form. 1006- 7 Acceptance Sampling and Testing : 1006- 7.01 General: Sampling and testing of concrete will occur to determine the acceptability of the concrete in accordance with the test methods and criteria identified below. Concrete satisfying the criteria shown in the following sections is acceptable for use in the work. Rejection of concrete delivered to the site may occur due to failure to satisfy or achieve the specified criteria including, but not limited to: improper temperature, slump, air content, or batch quantities that excessively TABLE OF CONTENTS INDEX 1186 deviate from the mix design. The Engineer may allow deficient concrete mixtures already placed to remain in place subject to final acceptance by the 28 day compressive strength testing provided there is confirmation that the placement had adequate consolidation throughout the pour. Deficient concrete mixtures due to insufficient air content, or improper slump which exhibit the appearance of segregation or lack of adequate consolidation, will not be accepted and shall be removed at no additional cost to the Department . For the mixture deli vered to the site, the weights and volumes shall be within the tolerances described in Subsection 1006- 4.02 of the specifications for each component. Acceptance and penalties for placed concrete which meets the specified mixture requir ements or is allowed to remain in place shall be determined by the results of the 28- day compressive strength as specified in Subsection 1006- 7.03 of the specifications, and additionally in the case of Class P concrete, on the measured thickness of concret e pavement in place as specified in Section 401 of the specifications . Sampling and testing for compressive strength will be performed on all classes of concrete furnished, including each strength specified on the project plans for ClassS concrete. 1006- 7.02 Field Sampling and Testing :
A sample of concrete for determination of temperature, slump, un it weight (when required), and air content (when required) as well as for fabrication of test cylinders for compressive strength determination at 28 days will be taken at random at the specified sampling frequency for each type of concrete. When “Self Consolidating Concrete” (SCC) is used, the concrete t est cylinders shall be fabricated, and unit weight and air content tests shall be performed as described in Subsection 1006- 4.05(E) of the specifications. All sampling and testing shall be done by a certified technician meeting the requirements of the ACI Concrete Field Testing Technician, Grade I or equivalent. Required testing of concrete will be performed in accordance with the methods shown in Table 1006- 9. TABLE OF CONTENTS INDEX 1187 TABLE 1006 -9 Sampling and Testing Test Procedures Temperature ASTM C1064 Slump ASTM C143 Air Content ASTM C231 or C173 Sampling ASTM C172 Making and Curing Cylinders ASTM C31 Compressive Strength ASTM C39 Unit Weight and Yield ASTM C138
Concrete shall be sampled in accordance with ASTM C172 for acceptance testing of temperature, slump, unit weight and yield (when required) and air content (when required) as well as for fabrication of test cylinders for compressive strength determination at 28 days except that the concrete shall be sampled once during discharge at the middle portion of the batch. Sufficient care shall be taken to obtain a representative sample by diverting the entire stream of the concrete to prevent segregation. Samples shall be of sufficient size to perform all the required tests and fabricate the necessary test cylinders but in no case less than 1 cubic foot. If the properties of the concrete do not appear to be within the specification mix design limits for slump, or ai r content, a preliminary sample may be obtained after discharge of 1/4 cubic yards for initial check testing. If the preliminary measurement falls outside the specified limits, concrete placement shall be discontinued and addressed as follows:
greater than the specified mix design upper limit, another check test shall be made immediately on a new test sample. In the event the second check test fails, the concrete shall be considered to have failed the requi rements of 1006- 7.03(A) and shall be rejected;
accordance with the requirements of 1006 -7.03(A). In place of the addition of water to adjust the slump, an approved water reducing admixture may be added to increase workability. After any additions, the drum shall be turned at least 30 revolutions at mixing speed and a check test shall be made on a new sample of the adjusted concrete to verify compliance wi th 1006- 7.03(A) ; and
specified limit, an approved air entrainment admixture may be added to increase the air content by an authorized representative of the ready mix supplier that has been approved b y the Engineer. After any additions, the drum shall be turned at least 30 revolutions at mixing speed and a check test shall be made on a new sample TABLE OF CONTENTS INDEX 1188 of the adjusted concrete to verify compliance with the mix 1006- 7.03(A). Preliminary samples for check testing do not take the place of acceptance samples. Once any additions, adjustments, and associated mixing are complete, another sample from the middle portion of the batch shall be taken for acceptance testing. All compressive strength test specimens shall be made, cured, handled, protected, and transported in accordance with the requirements of ASTM C31. A safe storage location(s)/facilities shall be secured for the use of the testing laboratory(ies)/technician(s) to ensure proper curing of concrete test cyl inders on the project site, including sufficient access on weekends and holidays to allow the timely pick- up of cylinders specimens. Upon arrival at the testing laboratory, all compressive test specimens shall be handled, cured, and tested in accordance wi th the requirements of ASTM C39. Any and all deviations from the standard procedure of any test method shall be promptly identified and corrected. Any deviations shall be clearly noted by the testing technician on reports. Should an individual cylinder show evidence of improper sampling, molding, curing, or testing, the results shall be discarded and the compressive strength shall be the result of the average of the remaining cylinder(s).Testing results obtained from non- standard testing procedures shall be considered invalid and discarded by the Engineer. If approved by the Engineer, and unless otherwise specified, Arizona Test Method 318 may be used to estimate concrete strength by the maturity method. The maturity method shall not substitute for compressive strength acceptance testing (28- day cylinders). The contractor shall submit a written request to the Engineer prior to using the maturity method. If its use is approved by the Engineer, the contractor shall develop a strength- maturity relationship an d shall also provide the maturity meter(s) and digital data loggers necessary, as well as performing all required testing, all at no additional cost to the Department.
Concrete pumped to facilitate placement shall be sampled for acceptance at the final point of placement. Samples shall be taken during continuous discharge of concrete without interruption at the normal production rate. In accordance with Subsection 601- 3.03 (C) of the specifications, where freeze- thaw durability is of concern (such as in bridge decks, overlays, approach slabs, and barrier walls), the concrete shall also be sampled at the truck to determine air loss through the pump. If the loss of air as measured between the supply truck and the point of placement exceeds 2 percent, the contract or shall employ measures acceptable to the Engineer to reduce the loss of air to less than 2 percent. If sampling at the point of placement is not practical, as determined by the Engineer, or creates a safety concern, the concrete shall be sampled for acceptance at the truck. When acceptance sampling can only be performed at the truck, the acceptable range of air TABLE OF CONTENTS INDEX 1189 content of the supplied mix will be adjusted to not less than 5 percent but no more than 8 percent in accordance with Table 1006- 10. For ClassS concrete with a compressive strength requirement less than 4000 pounds per square inch, or Class B concrete, a strength test will consist of the average strength of two test cylinders. However, if the compressive strengths of the two test cylinders differ by more than 10 percent from the average of the two, the strength test result shall be the cylinder with the highest compressive strength. For ClassS concrete with a compressive strength requirement equal to or greater than 4000 pounds per square inch, or Class P concrete, the compressive stre ngth of each sample shall be determined by averaging the results of the three test cylinders. However, if the compressive strength of any one of the three test cylinders differs by more than 10 percent from the average of the three, its result shall be di scarded and the compressive strength shall be the average of the remaining two cylinders. Should the individual compressive strength of any two of the three remaining cylinders differ by more than 10 percent from the average of the three, the results will be discarded and the compressive strength shall be the strength of the remaining cylinder.
Samples of concrete shall be taken in accordance with the requirements of ASTM C17 2, except concrete for Class P shall be sampled immediately before going into the paver or forms, or as otherwise directed by the Engineer.
The concrete will be field sampled and compressive strength tested by the Engineer in accordance with the requirements in 1006- 7.02 for Class S with the addition of the following: Fabrication of test cylinders for compressive strength determination shall be done for one day (for release breaks), seven days, and 28 days. The acceptance samples shall represent one member, one day’s production, or as determined by the Engineer.
A strength test on each precast unit produced wi ll consist of the average rebound number as determined from readings taken on the precast unit with a rebound hammer. The average rebound number will be determined in accordance with the requirements of ASTM C805. The compressive strength of the concrete will be determined from the average rebound number and the calibration chart established for the TABLE OF CONTENTS INDEX 1190 specific rebound hammer being used. The calibration chart will be established from rebound readings taken on concrete test cylinders fabricated at the precast plant and the actual compressive strength of the cylinders. 1006- 7.03 Acceptance Criteria: Concrete acceptance test results and verifications shall be evaluated for acceptance using the criteria established in this section.
Plastic concrete is concrete which has been delivered to the project, is still in a workable state, and has not yet achieved initial set. The criteria used for accepting plastic concrete are as follows:
The batch time is defined as the time at which cementitious material is combined with water or aggregate. Discharge from the truck mixer or truck agitator shall be completed within 90 minutes from batching. The Engineer may allow concrete placement to continue in excess of the 90 minutes if the concrete is of such slump, workability, and/or temperature that it can be placed without the addition of water to the batch. Additional discharge time shall also be allowed provided a hydration stabilizing admixture is shown on the approved mix design and has been included in the batch, subject to the following:
workability to facilitate adequate consolidation during placement, and;
requirements of subsection 1006 -2.04 of the specifications and retards hydration by a hydration stabilizing mechanism, and;
design, and the additional amount of batch to discharge time exceeding the 90 minute limit has been requested by the contractor for approval by the Engineer and acknowledged on the mix design by the Engineer, or;
the approved mix design and the application- specific dosage and additional time has been requested by the contractor and approved by the Engineer. TABLE OF CONTENTS INDEX 1191
The temperature of the concrete mixture immediately before placement shall not be less than 50 degrees F nor greater than 90 degrees F. The Engineer may allow concrete placement to continue in excess of the maximum temperature if the concrete is of such slump or workability that it can be placed without the addition of water to the batch. The Engineer may also approve concrete mixtures with a temperature less than 50 degrees F or greater than 90 degrees F if otherwise specified or pre- approved by a mix design that accounts for the temperature deviation. Otherwise, concrete that fails to conform to this temperature requirement will be rejected prior to placement.
The contractor shall furnish Class P Concrete having a slump within the range specified in Table 1006- 5. The contractor shall furnish ClassS and Class B concrete having the slump shown on the approved mix design, with a permissible variation of ± 1 inch when the slump shown on the approved mix design is 4 inches or less, and a permissible variation of ±1½ inches when the slump shown on the approved mix design is greater than 4 inches. However, when an approved high range water reducing chemical admixture (ASTM C494, Type F or T ype G) conforming to the requirements of Subsection 1006- 2.04 is used, the permissible variation will be ± 2 inches, unless otherwise required by the Special Provisions. Concrete that fails to conform to the consistency requirements will be rejected. When concrete is pumped, samples for consistency will be taken both as the concrete leaves the mixer and at the pump hose discharge. If the Engineer determines that there is a favorable correlation between the results of consistency tests on samples obtained f rom the mixer and from the pump hose, the Engineer may discontinue sampling from one of the sources. If a favorable correlation is not maintained, the contractor shall employ corrective measures acceptable to the Engineer and sampling will continue from both sources to verify the correlation of test results. If the workability of the concrete needs to be adjusted (or if additional mixing water is required to maintain the mix design water -cementitious material ratio), additional mixing water may be added as long as it does not exceed the amount of permissible water to meet the approved mix design maximum water tolerance, as noted on the delivery ticket. The concrete shall be mixed by a minimum of 30 revolutions of the drum at mixing speed after the water has been added, prior to discharge of any concrete for placement. The contractor shall ensure that any additional mixing water and required mixing revolutions shall be recorded on the delivery ticket as specified in Subsection 1006- 4.03(D) of the specifications. This additional mixing may be in excess of the maximum revolutions at mixing speed previously specified. TABLE OF CONTENTS INDEX 1192

*In accordance with Subsection 1006- 7.02 (A) of the specifications, when the concrete is pumped and acceptable sampling can only be performed at the truck.
Concrete that falls below the minimum may be adjusted with the addition of an approved air entrainment admixture in accordance with 1006- 7.02(A). Concrete that fails to conform to the maximum air content requirements listed above for the respective elevation as determined by the Engineer, shall be rejected prior to placement.
Class P concrete will be accepted for compressive strength in accordance w ith the provisions of Section 401 of the specifications. All concrete failing to meet the compressive strength requirement or otherwise rejected in accordance with Section 401 or Subsection 1006- 7.01 of the specifications , shall be replaced with concrete meeting the requirements of these specifications. If the contractor chooses to contest the compressive strength results of any sample for purposes of acceptability or improving a negative pay factor, the contractor may elect to rely on the results of compr essive strengths of cores. Three cores shall be obtained at no additional cost to the Department, at the approximate location where the contested test cylinders were obtained. Such cores shall be obtained and tested in accordance with the requirements of ASTM C42. Cores must be obtained under the observation of an ADOT representative and delivered to the Engineer in time to allow complete testing within 48 days of placement. Testing shall be performed by the Department. The contractor may elect to have a representative present during testing. Compressive strength shall be the average of the results of the three cores. However, if the compressive strength of any one of the three cores differs by more than TABLE OF CONTENTS INDEX 1193 10 percent from the average of the three, its r esult shall be discarded and the compressive strength shall be the average of the remaining two cores. Should the individual compressive strength of any two of the three cores differ by more than 10 percent from the average of the three, the results of both shall be discarded and the compressive strength shall be the result of the remaining core. Results of the core testing will be binding on both the contractor and the Department, and will replace the results of the test cylinders for that sample.
ClassS and Class B concrete will be accepted for compressive strength and paid for in accordance with the following table. Concrete will be paid for by the linear foot or by the cubic yard, complete in place, except that an adjustment in the contract unit price, to the nearest cent, will be made for the quantity of concrete represented by 28- day compressive strength test results less than the specified requirement. Concrete failing to meet at least 85 percent of the 28- day compressive strength for specified strengths of 3,000 pounds per square inch and below, 90 percent for a specified strength of 3,500 pounds per square inch, or 95 percent for specified strengths of 4,000 pounds per square inch and above, or any concrete failing to meet the other r equirements of Subsection 1006- 7.01 of the specifications, will be rejected and removed at no additional cost to the Department and replaced with concrete which meets the specified requirements, unless the contractor can submit evidence that will indicate to the Engineer that the strength Adjustment in Contract Unit Price for Compressive Strength of ClassS and Class B Concrete 3000 psi and Below 3500 psi 4000 psi and Above Percent of Specified 28- Day Compressive Strength Attained, to the Nearest 1 Percent Percent Reduction in Contract Unit Price (See Note 1) Percent of Specified 28- Day Compressive Strength Attained, to the Nearest 1 Percent Percent Reduction in Contract Unit Price (See Note 1) Percent of Specified 28- Day Compressive Strength Attained, to the Nearest 1 Percent Percent Reduction in Contract Unit Price (See Note 1) 100 or More 0 100 or More 0 100 or More 0 97 – 99 3 98 – 99 2 99 1 94 – 96 6 96 – 97 4 98 2 91 – 93 9 94 – 95 6 97 3 88 – 90 12 92 – 93 8 96 4 85 – 87 15 90 – 91 10 95 5 Less than 85 30 (See Note 2) Less than 90 30 (See Note 2) Less than 95 30 (See Note 2) Notes:

TABLE OF CONTENTS INDEX 1194 and quality of the concrete is such that the concrete should be considered acceptable and be allowed to remain in place. If such evidence consists of cores, the contractor shall obtain three cores from the concrete represe nted by the failing cylinder strength test. The cores shall be obtained at no additional cost to the Department, under the observation of an ADOT representative, and delivered to the Engineer in time to allow complete testing of such cores within 48 days after the placement of the concrete. All cores shall be obtained and tested in accordance with the requirements of ASTM C42. Testing shall be performed by the Department. The contractor may elect to have a representative present during testing. The concrete represented by the cores will be considered for acceptance, in accordance with the requirements of the table above. If the average compressive strength does not meet the specified requirement, all concrete so represented shall be removed at no additi onal cost to the Department unless permitted to remain in place by the Engineer. Results of the core testing will be binding on both the contractor and the Department, and will replace the results of the test cylinders for that sample. 1006- 7.04 Sampling Frequency for Cast -In-place Concrete:
For ClassS concrete with a compressive strength requirement less than 4000 pounds per square inch, a sample of concrete for the required tests, as specified in Subsection 1006- 7.02 of the specifications, will be taken on a daily basis for each 100 cubic yards, or fraction thereof, of continuously placed concrete from each batch plant. For ClassS concrete with a compressive strength requirement equal to or greater than 4000 pounds per square inch, a sample of concrete for the required tests, as specified in Subsection 1006- 7.02 of the specifications, will be taken on a daily basis for each 50 cubic yards, or fraction thereof, of continuously placed concrete from each batch plant. For Class B concrete, a sample of concrete for the required tests, as specified in Subsection 1006- 7.02 of the specifications, will be taken for each 100 cubic yards placed from each batch plant. For ClassS or Class B concrete placed at elevations of 3,000 feet or above, air content testing shall be performed for each 50 cubic yards placed, regardless of the compressive strength requirement. An additional sample or samples for any of the required tests may be taken at an interval of less than the sampling frequency specified above, at the discretion of the Engineer, on any batch or load of concrete. A sample for the required tests on daily placements of 10 cubic yards or less may be taken at the discretion of the Engineer.
Class P co ncrete shall be sampled and tested for compressive strength by the lot. A lot shall be considered to be one shift’s production; however, a new lot shall begin when the mix design is changed. For partial shifts due to weather or other reasons, more than one day’s TABLE OF CONTENTS INDEX 1195 production may be included in a lot. When such partial shifts occur, the contractor and the Engineer will jointly determine the lot limits. Five samples shall be obtained from each lot at random locations as directed by the Engineer. The Engineer may exclude certain locations from random sampling if the Engineer determines that the location of the work precludes normal construction operations. Three test cylinders shall be fabricated from each sample and tested for 28 -day compressive strength in accordance with Subsection 1006- 7.02 of the specifications. Class P concrete shall be sampled and tested for temperature, slump, and air content (if applicable) a minimum of five times per lot. The frequency may be reduced for partial shifts with the approval of the Engineer. Additional samples for any of the req uired tests may be taken at the discretion of the Engineer.
A sample of concrete for the required tests as specified in Subsection 1006- 7.02 of the specifications will be taken for either each precast concrete member or for each day's production at the discretion of the Engineer. An additional sample or samples for any of the required tests may be taken at the discretion of the Engineer. The Engineer will determine the quantity of concrete represented by each sample of concrete for any test performed. When a sample of concrete for the required compressive strength test is taken to represent a single day's production and not each precast member, the degree of acceptance for all precast concrete members in that day's production will be established by the results of such compressive strength test.

Pay adjustments for the virgin binder will be applied in accordance with Table 1005- 1. Should the asphalt -rubber or the virgin binder be deficient on more than one property from this table or Table 1005- 1, the pay adjustment will be the greatest r eduction to the contract price specified considering individual test results. The penalty will be applied to the total amount of asphalt -rubber. 1009- 2.04 Asphalt -Rubber Design: At least two weeks prior to the use of asphalt -rubber, the contractor shall submit an asphalt -rubber design prepared by an approved laboratory. The design shall be formulated using asphalt cement and crumb rubber that are representative of the materials to be utilized in production, and shall meet the requirements specified herein. The design shall show the values obtained from the required tests, along with the following information: percent, grade and source of the asphalt cement used; and percent, gradation and source(s) of crumb rubber used. In addition, the asphalt -rubber design shall include verification of the PG binder grade of the base asphalt; however, in lieu of the design including this information, a Certificate of Analysis conforming to Subsection 106.05 of the specifications from an accredited laboratory or the supplier of the PG base asphalt will be acceptable. If changes are made in the type or source of asphalt cement or in the type or source of crumb rubber, a new asphalt -rubber design will be required. TABLE OF CONTENTS INDEX 1206 The contractor may propose the use of an asphalt -rubber design that has been developed for a previous project. The proposed design shall meet the requirements of the specifications. The contractor shall provide evidence that the type and source of asphalt cement and the type and source of crumb rubber have not changed since the formulation of the previous design. The Engineer will determine if the previously used design is suitable for the intended use and if the previous use of the asphalt -rubber design was satisfactory to the Department. The Engineer will either approve or disapprove the proposed design. Should the Engineer disapprove the use of the previously used design, the contractor shall prepare and submit a new asphalt -rubber design proposal in accordance with t he requirements of the specifications. A previously used asphalt -rubber design more than two years old shall not be allowed for use. Once approved for use on a project, an asphalt -rubber design may be used for the duration of the project. 1009- 3 Construction Requirements: During production of asphalt -rubber, the contractor shall combine materials in conformance with the asphalt -rubber design unless otherwise approved by the Engineer. 1009- 3.01 Mixing of Asphalt -Rubber: The temperature of the asphalt cement shall be between 350 and 400 degrees F at the time of addition of the crumb rubber. No agglomerations of crumb rubber particles in excess of 2 inches shall be allowed in the mixing chamber. The contractor shall document that the amount of crumb rubber used does not deviate more than plus or minus 1.0 percent from the percentage specified in the accepted asphalt - rubber mix design. The temperature of the asphalt -rubber immediately after the initial dispersion of the crumb rubber into the asphalt cement shall be between 325 and 375 degrees F. The contractor shall ensure that the crumb rubber and asphalt cement for a particular batch have been thoroughly mixed and placed in the reaction tank prior to the beginning of the r eaction period. The reaction period shall be a minimum of sixty minutes, during which time the asphalt -rubber is continuously agitated while a temperature between 325 and 375 degrees F is maintained. At any time, if the temper ature falls below 325 degrees F, the reaction period shall begin anew when the temperature reaches 325 degrees F. The reaction period shall be completed before the asphalt - rubber is used. The contractor shall demonstrate that the crumb rubber particles have been uniformly incorporated into the mixture and that they have been “wetted”. The occurrence of crumb rubber floating on the surface or agglomerations of crumb rubber particles shall be evidence of insufficient mixing. The contractor shall test the viscosity of the asphalt -rubber in each batch by the use of a rotational viscometer, i n accordance with ASTM D7741. The rotational viscometer shall be furnished by the contractor or supplier. Prior to the use of each batch of asphalt -rubber, the results of TABLE OF CONTENTS INDEX 1207 the rotational viscosity testing shall meet the requirements given in Table 1009- 2. 1009- 3.02 Handling of Asphalt -Rubber: Once the asphalt -rubber has been mixed, it shall be kept thoroughly agitated to prevent settling of the crumb rubber particles. The temperature of the asphalt -rubber shall be maintained between 325 and 375 degrees F.

The additional information may include surface preparation requirements; mixing, placing and curing instructions; maximum amount of water to be used or maximum recommended consistency; unit weight and yield at maximum recommended water content or maximum consistency; recommended maximum usable working time, also called "pot -life," and approximate consistency at the end of that time; and the allowable temperature range for preparation and placement of the material. Nonshrink grout materials shall be stored in accordance with the manufacturer's recommendations at all times. Attention is directed to the characteristic of hydraulic cement materials to hydrate in the presence of moisture. Any material which shows evidence of hydration or does not appear suitable shall not be used. TABLE OF CONTENTS INDEX 1257 1017- 3 Directions for Use: Use of nonshrink grout materials shall be in accordance with the manufacturer's recommendations unless otherwise specified or limited by the Engineer. Use of nonshrink grout materials shall be allowed for only those uses as shown on the ADOT Approved Products List. At the time of mixing, the nonshrink grout materials shall be at a temperature within the range allowed according to the manufacturer's recommendations unless otherwise specified or approved by the Engineer. Any heating of the dry materials shall be done by application of indirect heat. The manufacturer may permit, in the package instructions, adjusting the mixing water temperature to achieve temperature limitations imposed for use of the grout materials. Immediately prior to use, the grout mixing apparatus shall be clean, prewetted, and drained, and essentially free of hardened grout and other foreign material that can be removed with a trowel or with a hammer, using reasonable effort. Water shall be added to the grout materials and the grout shall be thoroughly mixed to the desired consistency according to the manufacturer's recommendations. When thoroughly mixed, the nonshrink grout mixture shall have a uniform color. The amount of mixing water may be varied to achieve the desired consistency for the proposed use; however, the maximum recommended amount of mixing water shall not be exceeded. Surfaces on which the nonshrink grout material is to be placed shall be free of rust, paint, oil, grease, asphalt and loose or otherwise deleterious materials. The surface of existing concrete shall be roughened to ensure a good bond and shall be cleaned thoroughly with water, leaving existing concrete saturated, but free of standing water. Any overlay or inserted material which is to be bonded to the underlying surface shall be placed before the nonshrink grout material has begun to set. The nonshrink grout materials may be drypacked, troweled, flowed, pumped or vibrated into place unless otherwise recommended by the manufacturer. The method of placement depends on the application, but shall be in accordance with the manufacturer's recommendations. 1017- 4 Nonshrink Grout Material Requirements: Nonshrink grout materials placed against existing concrete shall be tested in accordance with the slant shear requirements of ASTM C882 by placing nonshrink grout against a dummy section of hardened Portland cement mortar. The slant shear test samples prepared in this manner shall provide a slant shear compressive strength of 1,000 pounds per square inch at seven days and 1,500 pounds per square inch at 28 days. TABLE OF CONTENTS INDEX 1258 The Vicat time of set for the material shall be determined in accordance with AASHTO T 131. The time of set shall be within 25 percent or 10 minutes of the time of set specified by the manufacturer, whichever is greater. The time of final setting shall be a maximum of eight hours. The compressive strength shall be determined in accordance with the requirem ents of ASTM C1107 . The minimum compressive strength at seven days shall be 2,500 pounds per square inch and the minimum compressive strength at 28 days shall be 5,000 pounds per square inch. Nonshrink grouts with high early strength development as stated by the manufacturer will be tested for conformance to the manufacturer's claims. The compressive strength of nonshrink grout material at 28 days shall be equal to or greater than the 28 day compressive strength requirement of the concrete to be patched. The expansion percent for the nonshrink grout material shall be determined in accordance with the requirements of ASTM C1107. The maximum expansion shall be 0.4 percent when measured at 3, 14, and 28 days. The percent shrinkage at 28 days shall be zero.
