The Importance of Concrete Recycling

Aggregate base course (road base) The largest application of recycled concrete aggregate (RCA) is for the aggregate base course in road construction.This term refers to the center layer of the roadbed. A cross-section of pavement would show dirt, or subgrade, as the lowest of three levels, layered on top by aggregate base course, and finally capped on top by pavement, either concrete or asphalt.
