303Stockpiled Surfacing Aggregate

303.01 Description

This is stockpiling surfacing aggregates at the specified location.

303.02 Materials

Furnish materials in accordance with Subsection 301.02 and the contract requirements.

303.03 Aggregate Stockpiling Methods

Clear stockpile sites of weeds, roots, stumps, rocks, and other contaminating matter. Dispose of this material in accordance with Subsection 201.03.5 or level as directed. Make the stockpile floor firm, smooth, well drained, uniform in cross-section, and able to support the stockpile. Place an aggregate bed on the floor to prevent stockpile contamination. Construct stockpiles in at least 3 layers. Place each layer approximately 4 feet (1.2 m) high before starting the next layer. Prevent each layer from spilling down over the next lower tier. Do not drop material stockpiled by conveyor more than 12 feet (3.7 m). Deposit the material in succeeding merging cone piles. Do not permit the piles to exceed 12 feet (3.7 m) in height. Level each completed layer to 4 feet (1.2 m) thick. Operate stockpiling trucks to produce a stockpile width that exceeds the single dump trucks width. Do not dump over the stockpile sides. Maintain separation between different gradation stockpiles to prevent aggregates from intermingling. Use equipment and methods to prevent segregation, degradation, or contamination of the aggregate when constructing stockpiles or delivering materials. Department sieve test samples are taken from the stockpile to determine degradation. Re-mix and re-stockpile segregated stockpiles. Bring stockpiled material failing specifications back within specifications at Contractor expense.
