Crushed Stone. Crushed stone or angular rock is a form of construction aggregate typically produced by mining a suitable rock deposit and breaking the rock down to the desired size using crushers. It can be made from marble, limestone, dolomite, granite or other rock that has been crushed and graded by screens to certain size classes.

· Crushed stone’s varying sizes and angular shapes make it an excellent base material for driveways and roads. It locks together under compaction, providing a stable surface. Conversely, #57 stone, with its uniform size and shape, is also used in these applications, particularly when consistent drainage and aesthetics are primary concerns.
