Crusher stone is generally limestone that has been crushed and graded by screens to certain size classes. Crushed stone may also be made from granite and other rocks. A special type of limestone crushed stone is dense grade aggregate, or DGA, also known as crusher run, or colloquially as ''crush and run''. This is a mixed grade of mostly small crushed stone in a matrix of crushed limestone powder. It is widely used in concrete and as a surfacing for roads and driveways, sometimes with tar applied over it.
