Cutback Bitumen RC30 is Rapid curing (RC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of rapid volatility. Cutback RC-30 containing minimum 50% Bitumen, is commonly used for Prime Coating.
Application of Bitumen Cutback RC30
Cutback agents are used to lower the viscosity of bitumen when it is applied as a primer to the surface of a road pavement aggregate base course or substrate. Kerosene is used as a bitumen cutback agent at different concentrations according to local conditions and requirements.
The cutback bitumen is ideal for prime coat and cold applied because of easy uses and no need to thinning and heating.
Bitumen RC30 Specification
Kiapetro guarantees that the Bitumen Cutback RC30 is produced in compliance and conformity to International of Standard ASTM/EN15322:2009, also meets the requirements of the following specification.
