800.01 General.
All materials used in th e work shall be new, unused material that will meet the requirements described in this Division unless the same are altered by specific requirements of any Section of these Specifications, Special Provisions , or by modifying notes on the plans. All materia ls shall also meet the requirements of applicable portions of Section 106 which will supplement the requirements of this Section. All tests shall be in accordance with the current Departmental testing schedule.
800.02 Inspection Arrangements.
a.Contractors' Notification . It shall be the duty of the Contractor to notify the Engineer of the source of the various materials required for each project. This notice shall be received sufficiently in advance of any shipment of materials so that inspection may be arranged at the producing plant if the Engineer so elects.
b.Plant Inspection . Whenever the quantity of materials warrants such an arrangement and/or it is economically advantageous to the Department, the inspection of materials at the original o r immediate source of supply will be made. However, the Department is under no obligation to the Contractor to inspect materials until it arrives at the site of the work. In general, all aggregates, soil, brick, reinforcing and structural steel, bituminous materials, timber, lumber, piling, and posts which are to become a part of the completed work will be inspected at the point of production. For timber, lumber, piling, and posts which are to be given preservation treatment, this inspection will be perform ed at the treating plant in conjunction with inspection of the treating process.
1.For lumber and timber products, the producer shall have sorted his stock and shall have separated a sufficient quantity of material to insure that all of each item for inspection is available before the Inspector is called. In the event that part of the shipment is rejected because of failure to meet the specification requirements, the producer shall furnish other stock to replace the rejected items.
2.Should the quantity of any material rejected for failure to meet specification requirements amount to 20 percent or more of the material inspected and tested at that time, the inspection operation will be suspended until the producer shall have regraded hi s stock or revised his production methods to produce material uniformly conforming with the specifications. When sampling stockpiles of aggregates, base materials, etc., the average of all samples must be within the gradation band required for the size ag gregate specified. In no case will stockpiles be acceptable if more than 20% of the total samples fall outside the gradation band. In addition, any failing sample must be within 20% of the range specified for any designated sieve.
3.In case the stock has not been properly prepared or separated before calling an Inspector, or in case of delay in replacement of rejected material, the extra inspection cost occasioned by such delay will be charged against the Contractor for whom the material is being produced and will be deducted from any sums due or which may become due the Contractor.
4.Where a Contractor's producer or jobber requests inspection of material for warehouse stock or for use in plants where stocks of materials inspected and accepted for use in h ighway construction or maintenance cannot be kept separated from materials which are to be used on other work, the cost of inspection of those materials which have been approved for highway work, but are later diverted to other uses not connected with the Department's highway construction or maintenance, will be charged to the Contractor who requested such inspections.
800.03 Testing, General.
Where maximum and minimum specification limits are given, it is intended and expected that materials having approxi mately mean values will be furnished under the respective specifications. The established allowances for variations in the determination of these values are considered in establishing the limits and no tolerances in excess of the established variation allowances will be permitted unless so specifically stated in the proposal or on the plans. Unless otherwise specified in the test procedure or material specification, all test results will be rounded off in accordance with ASTM E 29 and reported to the same n umber of places as the specification. Where material is fabricated of or treated with another material or any combination of materials is assembled to form a product, any or all of which are covered by these specifications, the failure of any of the compon ents of the product to comply with the designated specifications shall be deemed sufficient cause for the rejection of the whole. The sieves used for testing materials shall be woven wire cloth conforming to ASTM E 11 .
800.04 Tests for Concrete Materials.
Preliminary samples of fine aggregate, water, and cement shall be subject to both 7 and 28 day tests or their equivalent and acceptance based thereon. During the progress of the work, these materials may be accepted on the basis of the 7 day test, except t hat Type III cement may be accepted on the basis of the 3 day test.
800.06 Measurement of Liquid Bituminous Materials.
a.Measurement . Actual measurement shall be in accordance with the provisions of Subarticle 109.02(a) and/or (b).
b.Procedure . Unless otherwise provided in the proposal form, the procedure in conjunction wi th all shipments in tank cars or trucks shall be as follows:
1.The producer or supplier shall furnish to the Engineer in charge of the project a shipping notice (Form BMT -146) for each shipment, containing the following information: • Tank number and initia ls, if any. • Type, grade, and weight {mass} of bituminous material contained. • Date of Shipment. • Shipping Point. • Destination. • Consignee. • Project Number. • Temperature of bituminous materials, degrees Fahrenheit {Celsius}, at time truck tank was measured. Failure to furnish data will be cause for rejecting the shipment.
2.Before each shipment of bituminous material is unloaded, the Engineer shall be given opportunity to make such measurement as necessary to determine the net quantity of materials delivered.
3.Conversion of verified weight to gallons {mass to liters} may be used for measurement purposes provided prior written approval is obtained from the Engineer.
800.08 Field Performance Test.
In addition to specifications and tests specified, it may be necessary to have certain materials undergo field performanc e testing for a prescribed period. The materials involved and the specified field performance testing will be determined by the Department's Product Evaluation Board (PEB). The PEB will determine which type of material will require this field performance t esting and the duration thereof. In general, this will include materials such as Pavement Markers, Concrete Joint Fillers and Sealants, Concrete Patching Materials, Epoxies, Reflective Material for Object Safety Markings, Membranes for Waterproofing Joints , and certain pavement marking materials. SECTION 801 COARSE AGGREGATE
801.01 Description.
a.General . Coarse aggregate shall consist of crushed or uncrushed gravel, crushed stone, or crushed slag, having hard, strong, durable pieces, free from adherent coatings and conforming to the requirements provided in this Section. Gravel aggregate for use in bituminous plant mixes and bridge superstructure concrete (except prestressed concrete) shall have a bulk specific gravity greater than 2.550 (AASHTO T 85).
b.Acceptance . The Department has established a list of qualified producers of coarse aggregates. Refer to Subarticle 106.01(f) and ALDOT -355 concerning this list. All coarse aggregates furnished shall come from an approved producer who is participating in and meeting the requirements of ALDOT -249, "Quality Control Program for Acceptance of Fine and Coarse Aggregates". The producer's name shall be listed in the Department's "Materials, Sources and Devices With Specia l Acceptance Requirements" manual, List I -1.
801.02 Deleterious Substances.
Material suspected of containing deleterious substances will be examined in the laboratory and will be rejected if the amount is considered objectionable. Coarse aggregate for Port land cement concrete and cover aggregate for bituminous treatment shall be washed and shall be free from adherent coatings. Coating on crushed stone shall be dust of fracture as determined by washing the material passing the No. 200 {75 µm} sieve in accordance with AASHTO T 11 or visual inspection using a petrographic microscope. Adherent coating will be checked by washing in a large container without scrubbing or applying water pressure. The aggregate will then be checked for adherent coating by visual ins pection. Aggregate that has an adherent coating will not be acceptable. The amount of deleterious substances shall not exceed the limits shown in the following table.
