Coarse Washed Aggregates, Santa Rosa, California BoDean
Coarse washed aggregates are typically chosen when rock needs to be clean. Washing aggregates removes clay, dirt and debris from the rock. Once taken from the mountainside, the aggregate is taken to the BoDean Co. Wash Plant where it is cleaned with high powered jets and sorted into a variety of sizes for customers to select form.

Uses of Aggregates in Construction, Roads, Railway and Other
Aggregates are the most mined material in the world. Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as
