RC 250

Cutback bitumen RC 250 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.

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 application of RC-250 is in road pavement aggregate, 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-250   in compliance to the mentioned

specification in table.

 

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