grade bitumen asphalt can be applied on original asphalt which is AC (asphalt cement)grades or aged residue
AR(aged residue) grades.
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 AR viscosity grades asphalt cement are AR
1000, AR 2000, AR 4000, AR 8000. AR grades undergo processes in order to
simulated the natural conditions.
