Section 314 — Stockpiled Aggregates

Description

314.01This work consists of providing and placing aggregate in a stockpile for future use by the Government.

Material

314.02Conform to the following Section: Aggregate 703

Construction Requirements

314.03General. Conform to the gradation and q uality requirements specified in the Section identified for the material. After a representative quantity of aggregate is produced, submit proposed target values for the appropriate sieve sizes along with a representative sample size as specified in the Section identified for the material. Set target values within the gradation ranges shown in the applicable table for the required grading.

314.04Stockpile Site. Prepare a plan of operation. Perform work within a Government -furnished source only after a plan of operation for the development of the source is approved. Obtain CO approval before preparing sites. Prepare sites to prevent contamination of the stockpiles. Prepare sites as follows:

(a)For new sites, clear and grub according to Section 201;

(b)Grade, shape, and compact the site to a uniform cross- section that drains; and

(c)Place, compact, and maintain at least a 6 -inch lift of crushed aggregate over the stockpile site and access roads for stabilization. Obtain CO approval before stockpiling aggregates. 314.05 Stockpile. Build aggregate stockpiles in layers no more than 36 inches in thickness. Make the side slopes of each layer no flatter than 1V:1.5H. Spread aggregates with trucks or other approved pneumatic - tire equipment. Complete each layer before depositing aggregates on the next layer. Do not allow aggregates from the layer being built to run down over lower layers. Do not drop aggregates from a bucket or spout in one location to form a cone -shaped pile. Do not push aggregates into piles. Make the stockpiles neat and regular in shape. Do not track dirt or other foreign matter onto the stockpile material. Space stockpiles far enough apart or install partitions to prevent the mixing of aggregate gradations. Prote ct stockpiles with an approved cover.

314.06Acceptance. Aggregate for stockpiling will be evaluated under the Section identified for the material. See the table for sampling, testing, and acceptance requirements in the applicable Section, except the poin t of sampling for aggregate is from the stockpile. Subbase, base, surface course, and chip seal aggregate gradation, and surface course plasticity index will be evaluated under Subsection 106.05. Other aggregate quality properties will be evaluated under Subsections 106.02 and 106.04. Construction of stockpiles will be evaluated under Subsections 106.02 and 106.04. Clearing and grubbing will be evaluated under Section 201.

Measurement

314.07Measure the Section 314 pay items listed in the bid schedule according t o Subsection 109.02 and the following as applicable: When measuring aggregate by the cubic yard, measure in place.

Payment

314.08The accepted quantities will be paid at the contract price per unit of measurement adjusted according to Subsection 106.05 for the Section 314 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05.
