Bitumen RC-250 is Rapid curing (RC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of rapid volatility. Cutback Bitumen RC-250 is a rapid curing cutback bitumen that contains 65% bitumen, is black in color, and is manufactured strictly as per ASTM D 2028M standard.
Application of Bitumen Cutback RC250
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.
Cutback bitumen RC250 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction.
