The Importance of Concrete Recycling - thebalancesmb

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.Sustainability Case Study Review of Using Recycled,,mechanistic properties of the recycled materials relative to the conventional materials, the lifecycle costs of the recycled pavement structure are expected to be the same or lower than the conventional structure.
