Definition Of Cutback Bitumen RC-250
Cutback Bitumen RC-250 is Rapid curing (RC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of rapid volatility. Our Cutback Bitumen RC-250 complies with cutback petroleum asphalts of the rapid-curing type for use in the construction and treatment of pavements.
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. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function. RC–250 bitumen viscosity is between 250-500 CST.
Cutback Bitumen RC-250 is dissolved of bitumen in solvents of gasoline. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen.
The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long term softening effect may result.
Applications Of Cutback Bitumen RC-250
Current common uses are in penetrating prime coats and in producing patching or stockpile mixtures. Cutback asphalt used in mixing with aggregate will usually contain an adhesion agent to assist in the coating of the aggregate surface.
Packing Of Cutback Bitumen RC-250
This cutback bitumen bulk in the tanker and also in new steel and thick drum on the pallet to prevent all leak inside of the container.
