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.

Khaloo (1995) investigated the use of crushed tile as a source of coarse aggregate in concrete. The crushed tile had a lower density and a much higher water absorption value compared to those of natural crushed stones. The resulting concrete made with 100% crushed tile as the coarse aggregate had a lower density and higher compressive (+2%
Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
