EVALUATION OF NATURAL AND ARTIFICIAL AGGREGATES IN HOT MIX
River gravel is one out of such materials which is alternate materials used in road and asphalt production over the crushed stone due to its low cost effectiveness compared to crushed stone. The following are layers of flexible pavement which the river gravel can be used; the road sub-base, the road base and the wearing surface.

ARKANSAS RESOURCES FOR CRUSHED-STONE CONSTRUCTION AGGREGATE
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

Crushed Stone Aggregates
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

Production and Uses of Crushed Rock Aggregate from Intrusive
Aggregates are the most mined materials in the world. Commonly used aggregates include sand, crushed or broken stone, gravel (pebbles), broken blast-furnace slag, boiler ashes (clinkers), burned shale, and burned clay. Crushed aggregate in its own class, refers to a crushed stone product in quarries.

The use of crushed stone aggregate and marine sand is increasingly replacing natural aggregate, but these materials also cause various problems, such as ecosystem destruction and transportation-distance challenges [2]. Recycled aggregates are alternative resources to river or forest aggregates.
