AC 5 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 5 is a designed bituminous asphalt which is mostly

used in cold climate because the viscosity is low.

 

INTERNATIONAL BITUMEN SUPPLY guarantee to supply  the viscosity grade AC 5   in compliance to

 the mentioned specification in table.

 

Packing: Bitumen supply is able to provide every packaging according to customers enquiry.
