25kg bag 40mm-dust Crusher run
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.
