Section 311 Section 311 provided for jobsite slaked lime slurry in Subsection 307.04. Aggregate will be measured by the ton or cubic yard (LVM). When measurement is by weight, the weight of moisture, surf ace and hygroscopic, will be deducted. Processing will be measured by the square yard and shall include preparation of the roadbed, scarifying, pulverizing, drying of the material, mixing of the various materials, compaction of the mixture, finishing, protection and curing, and maintenance of the completed course. Bituminous curing seal will be measured by the gallon as prescribed in Subsection
109.01 Unless otherwise specified, distributor tank measurements will be used. The
volume of material over five percent above the allowed range for each shot will be deducted from measured quantities, except that 15 percent will be allowed for irregular areas where hand spraying is necessary. The volume of all bituminous material lost, wasted, damaged, or rejected, or applied outside of designated areas, or in excess of the Engineer's directions and tolerances allowed, or contrary to the specifications, will be deducted from measured quantities. Water will not be measured for separate payment.
311.05 Basis of Payment . The accepted quantities of lime and fly ash treated material
will be paid for at the contract price per ton for lime and fly ash, per ton or cubic yard (LVM) for aggregate, and per square yard for processing lime and fly ash treated material complete in place. The prices thus paid shall be full compensation for completing the work. Bituminous curing seal, measured as prescribed above, will be paid for at the contract unit price per gallon, which price shall be full compensation for furnishing, applying and reapplying if needed, protecting, maintaining; and all tools, equipment, labor and incidentals necessary to complete the work. Payment will be made under: 311-A: ___” Processing Lime and Fly Ash Treated Course - per square yard 311-B: Lime - per ton 311-C: Fly Ash, Class____ - per ton 311-D: Aggregate - per cubic yard or ton 311-S: Bituminous Curing Seal - per gallon SECTION 320 - SHOULDERS
320.01 Description . This work consists of constructing the shoulder portion of courses
specified to be constructed; the shaping, comp acting, finishing, and surfacing, if required, of the shoulder portion of the work in reasonably close conformity with the required lines, grades, and cross sections; and the construction and establishment of erosion control items specified for the shoulder portion of the work. All work shall conform to the sequence and timing indicated herein and to the other applicable requirements of the contract. This work shall also include preservation from injury or damage to and repair and reconstruction of, if necessary, underlying courses and other elements of the pavement structure. Except as otherwise specified, c onstruction of shoulders shall also include reshaping, finishing, and mowing of cut ditches, foreslopes, and upper embankment slopes adjacent to shoulders. Areas to receive this work shall include the areas between the finished shoulder line and the same elevati on at the back of the ditch in cut sections and the areas on fill slopes between the finished shoulder line and a line 12 feet horizontally outside the finished shoulder lin e. Similar areas in the median portion of divided highways shall also be reshaped and finished.
320.02 Materials . Materials used in constructing shoulders shall meet the applicable
requirements of Division 700.
320.03 Construction Requirements .
320.03.1 Preparation of Grade . Before beginning each course of shoulder
construction, the foundation shall be pr epared in accordance with Section 321.
320.03.2 Construction Details . Except as otherwise specified, the construction of each
course of the shoulders shall be in accorda nce with controlling requirements for bases constructed of like material. Shoulder construction shall begin at the earliest practicable time and proceed in the proper sequence with contiguous base or pavement construction. Each designated course for shoulders shall be constructed to the es tablished lines, grades, and cross sections within tolerances allowable under Section 321 and shall be firm and stable; reference is made to Subsection 321.03. Determination of acceptance of compaction of shoulders for required density will be performed on a lot to lot basis. Each lot will consist of each day's operation per layer placed, with a maximum lot le ngth of 10,000 linear feet. The lot will be divided into five approximately equal sublots with one density test taken at random in each sublot. The lot average and each single density test shall conform to the required density. The required density for the shoulder portion of any layer or course shall be the same as for the adjacent (internal) portion of the layer or course when constructed of the same material. The required density for the shoulder portion of any layer or course where the adjacent (internal) portion is of unlike material shall be as follows: Granular Material Lot Individual Class Average Test 10 94.0 90.0 7,8 or 9 95.0 91.0 5 or 6 96.0 92.0 3 or 4 97.0 93.0 1 or 2 98.0 94.0 except,
a.When the finished shoulder is required to be paved, the required density for such shoulder course shall be that required for the same material for bases, and
b.Where an existing pavement is to be overlaid, or widened and overlaid, without shoulder widening, and the existing shoulder is to be raised to match the new pavement, satisfactory density of each layer of new shoulder material shall be that which can be obtained from six coverages of a pneumatic roller with an operating weight of approximately six tons while the shoulder material is at the proper moisture content. In cases of base or pavement in which cement is used as a material of construction, shoulder construction shall follow immediately upon expiration of the curing period, unless it has been otherwise provided that the shoulder course be constructed in advance of the contiguous course. The rate of progress for each phase of shoulder construction shall be consistent with the rate of progress of the controlling construction. When the Engineer deems that other operations are being carried on to the unnecessary neglect of shoulder construction, the Engineer may suspend the operations in progress and order that shoulder construction be brought up to and then continued, without prejudice to other work, in the proper sequence.
320.04 Blank .
320.05 Basis of Payment . Unless otherwise specified in the contract, no separate
payment will be made for shoulder construction. Payment will be made for the materials and their processing when set up in the contract as pay items. All additional work involved in shoulder construction is considered an obligation of the Contractor subsidiary to the placement of the materials required a nd work performed for which provisions for payment are contained in the contract. SECTION 321 - IN-GRADE PREPARATION
321.01 Description . The term "in-grade preparation" is defined as the work required to
prepare, blade, shape, scarify, disk, mi x, compact, etc. the existing material to specification requirements prior to placement of a subsequent course of material. Figure 1, Section 101, graphically defines the limits of the roadway, the design soil and the components of the pavement structure. In-grade preparation shall be in reasonable close conformity with the lines, grades, and
