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.

Gravel material that has not been processed through a crusher or screened. Consists of rounded stones, sand, and silt. Sizing depends upon where in the gravel deposit the material was dug from and the rocks in it can range from small stones to large boulders. Typically used as a fill material. √HQ √WL.
