Crushed Aggregate Base Course Specifications for ...

Aggregates are materials such as gravel, sand and crushed stone that provide an important ingredient in concrete. An aggregate base course is the layer of soil installed between the surface pavement layer and the foundation soils of either asphalt or concrete pavement. (If two layers of aggregate base courses are installed above the subgrade, they ...
