    Crushed stone is one of the most accessible natural resources, and is a major basic raw material used by construction, agriculture, and other industries. Despite the low value of its basic products, the crushed stone industry is a major contributor to and an indicator of the economic well-being of a nation. The demand for crushed stone is determined mostly by the level of construction activity, and, therefore, the demand for construction materials.

Crushed stone is a commercial product made by mining rock and crushing it into angular pieces. Gravel is a natural material that consists of water-transported particles of rock that are larger than two millimeters in diameter and usually have a rounded shape as a result of their water transport. The shape of the grains and mans role in producing them are the differences that separate crushed stone from gravel.
