What is Crushed Concrete Aggregate-Can I use it as Base

Rather than being discarded as waste, this concrete is broken down into small pieces, commonly ranging from 3/4 inch to fine powder, and then screened to remove any contaminants. Crushed concrete aggregate can be used in a variety of construction applications, such as a base material for new roads, pavements, and parking lots, as a

Grading curves of crushed stone fine aggregate and sand.

Granular A Gravel | 3/4 Minus Gravel | ASTM D2940

Granular A, A Gravel, or 3/4 inch minus is a mixture of sand and crushed gravel or rock. With mechanical compaction and reaching 98% standard Proctor Density, this material provides adequate stability and load support for paver bases. Through this compaction and with the loads that the base will bear, the coarse aggregate should not degrade.
