Section 311. — STOCKPILED AGGREGATE

(ADDED SECTION)

Description

311.01 This work consists of crushing material from a Government-provided material source and constructing stockpiles of the processed select borrow and aggregate surface course at designated sites prepared by the Contractor.

This work also consists of providing riprap material from a Contractor-located material source and constructing a stockpile of the material at a Contractor-prepared designated site within the Toklat Pit.

Material

311.02 Definitions.

(a) Waste. Unsuitable aggregate surface course and select borrow material.

311.03 Conform to the following Subsections:

Surface Course Aggregate 703.05 (a) and (d) Select Borrow 704.07 Riprap Rock 705.02 Bentonite 725.23

Construction Requirements

311.04 Production. Produce aggregate surface course as specified under Section 703. Produce select borrow as specified in Section 704. Produce class 5 riprap as specified in Section 705.

After a representative quantity of aggregate is produced, determine the amount (percent by mass) of bentonite to be added to the crushed surface course aggregate to meet the plasticity index requirement in Subsection 703.05.

311.04A Mixing. Incorporate the amount of bentonite required to meet the plasticity index requirement in Subsection 703.05 into the surface course aggregate as follows:

Use a stationary pugmill with weighing or metering equipment capable of accurately controlling the material entering the mixer. Interlock the metering controls for the aggregate feed with those of the bentonite to ensure uniform introduction of material into the mixer.

Maintain the accuracy of the amount of bentonite added to within 0.5 percent by mass of the target rate determined under Subsection 311.04.

311.05 Stockpiling. Prepare existing sites as necessary to accommodate the quantity of select borrow, aggregate surface course, and riprap to be stockpiled and provide a uniform cross-section that drains.

Revised by Amendment A001

F-17

Obtain site approval before stockpiling aggregates, select borrow, or riprap. Construct the stockpiles neat and regular in shape, with sideslopes no flatter than 1.5:1. Build the stockpiles in layers not to exceed 4 feet in thickness. Construct stockpile layers by spreading materials with trucks or other approved pneumatic-tired equipment. Complete each layer before beginning subsequent layers.

Do not push aggregates into piles. Do not dump the aggregate so any part of it runs down and over the lower layers in the stockpile. Do not drop aggregates from a bucket or spout in one location to form a cone-shaped pile.

Do not stockpile aggregate where traffic runs through the piles. When operating trucks on stockpiles, use plank runways, where required, to avoid tracking dirt or other foreign matter onto the stockpiled material.

Space stockpiles far enough apart or separate stockpiles by suitable walls or partitions to prevent the mixing of the different aggregate gradations.

After completion of the project, process the remainder of the Government furnished stockpile at Toklat Pit to consist of 70 percent aggregate surface course and 30 percent select borrow.

311.06 Waste Material. Dispose of processing waste material according to Section 105 and as directed by the CO. Aggregate surface course waste material may be combined with select borrow waste material.

311.07 Acceptance. See Table 311-1 for sampling and testing requirements.

Aggregate will be evaluated under Subsections 106.02, 106.04, and Table 311-1.

Select borrow will be evaluated under Subsections 106.02, 106.04, and Table 311-1.

Riprap rock will be evaluated under Subsections 106.02, 106.04, and Table 311-1.

Bentonite will be evaluated under Subsection 106.03.

Measurement

311.08. Measure the Section 311 items listed in the bid schedule according to Subsection 109.02 and this Subsection.

Measure stockpiled aggregate designated to remain in place at Toklat Pit upon completion of the project by the cubic yard in its final stockpiled position.

Measure stockpiled select borrow designated to remain in place at Toklat Pit by the cubic yard in its final stockpiled position.

Measure bentonite by the ton.

Inform the CO one day prior to measurement of a stockpile.

Do not add to a stockpile that has been measured. Start subsequent stockpile(s) if needed.

F-18

Payment

311.09 The accepted quantities, measured as provided in Subsection 109.02 and above, will be paid at the contract price per unit of measurement for the Section 311 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05.
