Crushed Stone. Crushed stone is used as aggregate in construction material uses. The most common types of rock processed into crushed stone include limestone, dolomite, granite, and traprock. Smaller amounts of marble, slate, sandstone, quartzite, and volcanic cinder are also used as construction aggregates.
How is crushed stone mainly used?
Most crushed stone is used for construction purposes, mainly as aggregate with or without a binder. Road base or road surfacing material, macadam, riprap, and railroad ballast are the major uses without a binder.
What are the characteristics of a stone?
Most types of stone in the earth's crust have similar densities. A dense stone like granite will offer superior durability and strength. Other examples of dense stones include basalt, dolomite, and slate. Porosity is the amount of open space between mineral grains in a stone (and generally dictates permeability).
