Aggregates may be produced by processing sand and gravel or by blasting and crushing bedrock materials or select by-product materials, including recycled/reclaimed materials, such as concrete, asphalt, blast furnace slag, glass and ceramics, etc. Crushed stone and processed sand and gravel are interchangeable for many applications, but not all.

Asphalt density ranges from 2,200 to 2,400 kg/m³ (or approximately 138 to 150 lb/cu. ft). The higher the density of the asphalt, the more durable it is. In our asphalt calculator, we used 2,400 kg/m³ as the default density to give a conservative estimation. You can, however, change this value if you know the density of the asphalt mix you'll use.
