The USGS is studying the economics and practical aspects of recycling aggregate that has been used in cement concrete and asphalt.  Recycling cement concrete and asphalt can reduce the amount of material placed in landfills.

Recycling can take place on the demolition site or materials can be transported to an aggregate recycling facility. Recycled material can supplement the supply of natural aggregate.
