Asphalt concrete (AC) is a composite material composed of mineral aggregates adhered with a bitumen binder. Asphalt concrete is commonly called as asphalt, blacktop, bituminous concrete or DBM (Dense Bitumen Macadam). It is used to surface roads, parking lots, airports etc. The viscous nature of the bitumen binder allows asphalt concrete to sustain significant plastic deformations. Asphalt is usually mixed, spread and compacted while it’s hot, and is therefore classified as a Hot Mix Asphalt. It has a continuous distribution of aggregate particle size and filler, and low design air void content, ranging from 3to5% .Rutting due to excessive permanent deformation, cracking due to fatigue, and hardening of the binder are common modes of failure for Asphalt Concrete. Therefore, attempts to improve the performance of asphalt concrete are constantly being investigated.
