Cutback bitumen RC800 is dissolved of bitumen in solvents of Naphtha. Petroleum solvents such as naphtha, kerosene, etc. are cutback agents which can reduce the viscosity of bitumen. As well as improving the ability to coat aggregates.
Typical amount of solvent or distillate in a cutback bitumen is from 12% to 40%.
gasoline or naphtha is used as the solvent in order to manufacture rapid curing bitumen cutback. RC-800 is one of the examples of a rapid curing cutback bitumen.
Cutback asphalt is an asphalt cement that has a solvent or distillate such as gasoline, diesel fuel, kerosene, or naphtha added to make the asphalt liquid at ambient temperatures and improve its ability to coat aggregates.
The main applications of RC-800 are in road pavement, tack coat and prime coat.
naphtha is used as a bitumen cutback agent at different concentrations according to local conditions and
requirements.
Cut back bitumen are easy to use because it is cold applied. Cut back grade bitumen is normally used in spraying. Rapid curing cutback petroleum asphalt supplied by bitumen supply manufacturing from vacuum distillation of crude oil blended with a petroleum solvent.
INTERNATIONAL BITUMEN SUPPLY guarantee to supply the cut back asphalt RC-800 in compliance to the mentioned
specification in table.
