Develop pit in accordance with Section 651.

Submit a written quality control plan and perform the Contractor quality control and inspections according to Section 153.

No quality requirements or no gradation other than maximum size will be required for pit run and grid-rolled material. For grid rolling, use all suitable material that can be reduced to maximum size.

After processing on the road, remove all oversize material from the road and dispose of it as directed by the CO.

Provide additives or binder, if required, at the proportions specified.

If the aggregate is produced and stockpiled before placement, handle and stockpiled according to

Section 320. Establish stockpile sites at approved locations.

321.04 Mixing and Spreading. Mix the aggregate and adjust the moisture content to obtain a uniform mixture with a moisture content suitable for the specified compaction method. Spread and shape the mixture on the prepared surface in a uniform layer with no segregation of size, and to a loose depth that will provide the required compacted thickness.

Do not place in layers exceeding 6 inches in compacted thickness for aggregate base and surface courses or twice the maximum particle size for screened aggregate. When more than one layer is necessary, compact each layer according to Subsection 321.05 before placing the next layer.

Route hauling and leveling equipment uniformly over the full width.

When placing aggregate over geotextile, place aggregate in a single lift to the full depth specified.

When additives are specified ensure that aggregate, additives, and any required water, mineral filler, and binder are mixed by the specified method. Control additive proportions to 0.5 percent dry weight.

Additive Mixing Methods:

(a) Stationary Plant Method. Mix the aggregate with other required materials in an approved mixer. Add water during the mixing operation in the amount necessary to provide the moisture content for compacting to the specified density. After mixing, transport the aggregate to the jobsite while it contains the proper moisture content, and place it on the roadbed or base course using an aggregate spreader.

(b) Travel Plant Method. After placing the aggregate for each layer with an aggregate spreader or windrow-sizing device, uniformly mix it with other required materials using a traveling mixing plant or rotary mixer. During mixing, add water to provide the necessary moisture content for compacting to the specified density.

(c) Road Mix Method. After placing the aggregate for each layer, mix it with other required materials at the required moisture content for compacting to the specified density until a uniform distribution is obtained.

321.05 Compacting. Compact each layer full width. Roll from the sides to the center, parallel to the centerline of the road. Along curbs, headers, walls, and all places not accessible to the roller, compact the material with approved tampers or compactors.

Compact the aggregate using one of the following methods as specified:

Compaction A. Adjust the moisture content to a level suitable for compaction. Operate spreading and hauling equipment over the full width of each layer of the aggregate.

Compaction B. Operate rollers and compact as specified in Subsection 204.11.

Compaction C. Moisten or dry the aggregate to a uniform moisture content between 5 and 7 percent based on total dry weight of the mixture. Operate rollers and compact as specified in

Subsection 204.11(a).

Compaction D. Compact each layer of aggregate to a density of at least 95 per-cent of the maximum density, as determined by AASHTO T 99, method C or D.

Compaction E. Compact each layer of aggregate to a density of at least 96 percent of the maximum density, as determined by the Modified Marshall Hammer Compaction Method

(available upon request from USDA Forest Service, Regional Materials Engineering Center, P.O.

Box 7669, Missoula, MT 59807).

Compaction F. Compact each layer of aggregate to a density of at least 95 per-cent of the maximum density, as determined by AASHTO T 180, method C or D.

Compaction G. Compact each layer of aggregate to a density of at least 100 percent of the maximum density as determined by the Modified Marshall Hammer Compaction Method

(available upon request from USDA Forest Service, Regional Materials Engineering Center, P.O.

Box 7669, Missoula, MT 59807).

Compaction H. Compact the aggregate by operating compaction equipment over the total width until visible deformation ceases. A minimum of five complete passes shall be made at a moisture content suitable for compaction.

Compaction I. Adjust the moisture content to a level suitable for compaction. Operate rollers over the full width of each layer until visual displacement ceases, but not fewer than three complete passes. Use rollers that meet the following requirements:

(1) Steel wheeled rollers, other than vibratory, capable of exerting a force of not less than 250 pounds per inch of width of the compression roll or rolls.

(2) Vibratory steel wheeled rollers equipped with amplitude and frequency controls with a minimum weight of 6 tons, specifically designed to compact the material on which it is used.

(3) Pneumatic-tired rollers with smooth tread tires of equal size that will provide a uniform compacting pressure for the full width of the roller and capable of exerting a ground pressure of at least 80 psi.

For all compaction methods, blade the surface of each layer during the compaction operations to remove irregularities and produce a smooth, even surface. When a density requirement is specified, determine the in place density and moisture content according to AASHTO T 310 or other approved test procedures.

321.06 Construction Tolerance. If grade finishing stakes are required, finish the surface to within ±0.05 feet from staked line and grade elevation.

If grade finishing stakes are not required, shape the surface to the required template and check the surface with a 10-foot straightedge. Defective areas are surface deviations in excess of 1/2 inch in 10 feet between any two contacts of the straightedge with the surface.

Correct all defective areas by loosening the material, adding or removing material, reshaping, and compacting.

Ensure that the compacted thickness is not consistently above or below the specified thickness.

The allowable average thickness of four random measurements for any ½ mile of road segment is within + ¼ inch of the specified thickness. The maximum variation from the compacted specified thickness is ½ inch.

Ensure that the compacted width is not consistently above the specified width. The allowable average width of any four random measurements along any ½ mile of road segment is within +4 inches of the specified width. The maximum variation from the specified width will not exceed

+12 inches at any point.

321.07 Maintenance. Maintain the aggregate course to the correct line, grade, and cross-section by blading, watering, rolling, or any combination thereof until placement of the next course. Correct all defects according to Subsection 321.06.

321.08 Acceptance. See Table 321-1 or Table 321-2 as applicable, for sampling and testing with the exception of that the point of sampling will be from the windrow after processing or from the roadbed.

Aggregate gradation and surface course plasticity index will be evaluated under Subsection

106.05. If the aggregate is obtained from a Government stockpile then the above characteristics will be evaluated under Subsection 106.02. Other aggregate quality properties will be evaluated under Subsections 106.02 and 106.04. Placement of aggregate courses will be evaluated under

Subsections 106.02 and 106.05.

The allowable upper and lower aggregate gradation limits are the Target Value plus or minus the allowable deviations shown in Tables 703-2 and 703-3.

The allowable upper and lower Plasticity index limits for surface courses are stated in 703.05(b).

Preparation of the surface on which the aggregate course is placed will be evaluated under

Section 204 or 303 as applicable.

Measurement

321.09 Measure the Section 321 items listed in the bid schedule according to Subsection 109.02 and the following as applicable.

Measure square yard width horizontally to include the top of aggregate width including designed widening. Measure the square yard length horizontally along the centerline of the roadway.

If the measurement for aggregate is by cubic yard using contract quantities then measure aggregate by the cubic yard in-place once compacted, otherwise measurement for aggregate by the cubic yard is measured by the cubic yard in the hauling vehicle.

Measure thickness perpendicular to the grade of the travelway.

Measure width perpendicular to the centerline.

Payment

321.10 The accepted quantities will be paid at the contract price per unit of measurement adjusted according to Subsection 106.05 for the Section 321 pay items listed in the bid schedule.
