The Importance of Concrete Recycling - thebalancesmb.com
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. This application is widely accepted for recycled concrete by Departments of Transportation.
