Description
Crushed stone is used as aggregate in construction material uses. The most common types of rock processed into crushed stone include limestone, dolomite, granite, and traprock. Smaller amounts of marble, slate, sandstone, quartzite, and volcanic cinder are also used as construction aggregates.
Relation to Mining
Crushed stone is produced in every state in the U.S. except Delaware. The type of crushed stone mined from any particular state depends on the general geology and rocks of the state. For instance, crushed limestone and dolomite are typical in Indiana, Illinois and Ohio, whereas marble and granite come from Vermont.
Texas, Pennsylvania, Florida, Georgia, Illinois, Missouri, Ohio, North Carolina, Virginia and Kentucky account for more than half of the total U.S. crushed stone production. Most states recycle asphalt, concrete and construction and demolition debris for alternative construction materials to virgin aggregate sources.
The United States does import small amounts of crushed stone from Canada, Mexico and the Bahamas. Crushed stone is a heavy commodity of relatively low value. Therefore, it is more economical to use the product in a construction setting close to a population center that is also close to the mining source in order to limit the cost of transportation.
Uses
Crushed stone is used mostly as aggregate for road construction and maintenance. It is also used for making cement and lime and other chemical applications, and in agriculture. There are other uses for crushed stone, many of which are not accurately or completely reported.
