Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the secondmostused substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined.

The aggregates are used for the surface course of the highway pavements and they are subjected to wearing due to movement of traffic. (L os Angeles abrasion test ASTM c131). When vehicles travel on the road, the soil particles present between the pneumatic tyres of vehicle and road surface creates the abrasion effect on aggregates.
