AC 30 Grade

Viscosity grade bitumen asphalt can be applied on original asphalt which is  AC (asphalt cement)grades or aged residue AR(aged residue) grades.

AC grades indicated viscosity at 60 °C actually the number after AC showed 0.01 absolute viscosity in poises at 60 °C. 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 30 is a designed bituminous asphalt which is mostly used in hot climate because the viscosity is high.
