Aggregate Pavement InteractiveAggregate is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium such as water, bitumen, portland cement, lime, etc. to form compound materials such as asphalt concrete and portland cement concrete. By volume, aggregate generally accounts for 92 to 96 percent of HMA and about 70 to 80 percent of portland cement concrete.
