crushed rock screening technics

Crushed stone driveways: Besides limestone, granite, gneiss, dolomite and trap rock are popular for driveways. The stone is screened and sorted for size; the angled rather than round edges cause the stones to support one another to create a stable base. The color of crushed stone for driveways varies widely, and they can be dusty like limestone.
