RC70 cut back bitumen
RC70 rapid curing bitumen is one of the types of cutback bitumen, which is black in color and contains 55% pure bitumen. RC70 cutback bitumen has a low viscosity among rapid curing cutback bitumens. The kinematic viscosity of bitumen solution is RC70.
After distilling the solvent in RC70 cutback bitumen, 55% pure bitumen remains. This bitumen has 0.2% water in its composition. In fact, cutback bitumens are classified according to their evaporation time.
The abbreviation RC stands for Rapid Curing Bitumen, which is produced by mixing pure bitumen with a light solvent such as gasoline or kerosene. From the combination of pure bitumen with industrial solvents, there are three types of rapid curing cutback bitumen.
The difference between rapid curing cutback bitumen depends on the quality of pure bitumen and the type of solvent. The higher the amount of light solvent in the production of soluble bitumen, the earlier and faster its fluidity and evaporation. As a result, the speed of sticking pure bitumen to asphalt is increased and the work goes faster.
Application of RC70 rapid curing cutback bitumen
RC70 rapid curing cutback bitumen is mainly used in cases such as making protective asphalts, making single-layer and multi-layer asphalts, bitumen spraying and surface coating. Also, this bitumen can be used for permeating macadam asphalt with a lot of empty space and sealing coating with stone materials.
Buy RC70 cutback bitumen
The price of RC70 cutback bitumen depends on various factors. Among the factors influencing the price of bitumens, we can mention the production company, exchange rate, physical and chemical characteristics, as well as the materials used to produce cutback bitumen.
