SC 250

Cutback bitumen is a kind of bitumen which is made by mixing penetration grade with petroleum solvents. The curing time of the cutback bitumen determined whether it is rapid caring, medium caring or slow caring. Slow caring bitumen are obtained by mixing with heavy solvents. These category of bitumen are called road oil which often use in road mixing. Slow caring cutback bitumen are often use for penetrating prime coat, coating, surface primer, road pavement. The viscosity of bitumen reduces remarkably facilitates construction of seal coats in road pavements as softened.

 

Cutback bituminous asphalt SC-250 applied to waterproofing surfaces. The SC-250 bitumen can be obtained by mixing an asphalt cement with a heavy solvent such as gas oil.

Slow curing cutback petroleum asphalt supplied by bitumen supply manufacturing from vacuum distillation of crude oil blended with a petroleum solvent.
