Aggregates Sodium Chloride
803
803.12.4
310.3EQUIPMENT
1 Unless otherwise approved by the engineer, use a pugmill capable of thorough and
consistent blending to mix water and aggregate or sodium chloride and aggregate.
310.4CONSTRUCTION
310.4.1 General 1 Furnish, deliver, and place aggregate in stockpiles at designated sites.
Ensure that the sites are firm, smooth, and well drained. When required, clear and grub sites in accordance with Section 201, Clearing and Grubbing. Remove and stockpile topsoil in accordance with Section 207, Topsoil. 2 To prevent the intrusion of soil or foreign material, place a bed of the same aggregate
being stockpiled under the stockpile. Make the bed at least 6 in [150 mm] deep, and extend it at least 10 ft [3 m] beyond the edge of the stockpile. 3 To prevent mixing, separate stockpiles of different types or sizes of aggregates by spacing
them at least 30 ft [10 m] apart or by using suitable walls or partitions. 4 Do not use stockpiling methods that allow contamination or excessive degradation of the
aggregate. The engineer will use gradation tests to evaluate degradation. If samples fail to meet gradation requirements, the engineer will reject stockpiled aggregates. Change stockpiling procedures to provide the specified gradation. 5 When specified, blend sodium chloride uniformly with the aggregate.
