Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing

The crushed stone industry is important in the economy of Arkansas. In spite of a comparatively low population, Arkansas ranked 19th in the nation in production of crushed stone in 1996 (U.S. Geological Survey, 1997a). In the same year, crushed stone accounted for nearly 40% of Arkansas’ non-fuel mineral production value, with a total raw
