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 20 is a designed bituminous asphalt which is mostly

 used in hot climate because the viscosity is high.

INTERNATIONAL BITUMEN SUPPLY guarantee to supply  the viscosity grade AC 20   in compliance to

the mentioned specification in table.
