The Complete Guide to Crushed Stone and Gravel

Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
