Many types of crushed stone: Crushed stone is not a "standardized commodity." It is made by mining one of several types of rock such as limestone, granite, trap rock, scoria, basalt, dolomite, or sandstone; crushing the rock; and then screening the crushed rock to sizes that are suitable for the intended end use.
