AC General designation for Asphalt Concrete. Asphalt Concrete is a continuously graded or gap-graded bituminous mixture in which the aggregates form an interlocking structure. The designation of AC is followed by an indication of D, the upper sieve size of the aggregate in the mixture, in millimetres (mm) and the binder designation.

For instance, AC-5 means the bituminous asphalt cement has viscosity of 500 poises at 60°C. The number after AR indicated viscosity in poises at 60 °C. Common viscosity grades asphalt cement are AC-2.5,AC-5,AC-10,AC-20, AC-30,AC-40. AC 20 is a designed bituminous asphalt which is mostly used in hot climate because the viscosity is high.
