Cutback Bitumen RC-70

Cutback Bitumen Rapid Curing 70 (RC-70) is a type of cutback bitumen that is blended with a fast-evaporating petroleum solvent to lower its viscosity, making it easier to apply at lower temperatures. The "70" indicates its viscosity grade, suggesting it has a relatively low viscosity compared to other grades of cutback bitumen.

Main Applications Of Cutback Bitumen RC-70

The main applications of Cutback Bitumen Rapid Curing 70 (RC-70) are in road construction and maintenance, particularly where quick setting and effective bonding are essential. Key applications include:

Prime Coating: Cutback Bitumen RC-70 is often used as a prime coat on granular or unbound surfaces to prepare them for asphalt layers, promoting strong adhesion.
Surface Dressing: It is applied in surface dressing, where it is sprayed onto road surfaces and then covered with aggregate to create a durable, protective layer.
Cold Mix Asphalt: Cutback Bitumen RC-70 is utilized in cold mix asphalt for repairing potholes and other surface defects, allowing for quick repairs without the need for heating.
Dust Control: It can be used to control dust on unpaved roads by binding loose particles together, enhancing road surface stability.
Crack Sealing: Cutback Bitumen RC-70 is effective for sealing cracks in pavements, preventing moisture infiltration and extending the lifespan of the road.
Chip Sealing: It is used in chip sealing applications to provide a quick-setting binder for the aggregate, improving road surface texture and durability.

Cutback Bitumen RC-70's rapid curing and easy application make it ideal for projects requiring fast results and strong bonding, especially in varying weather conditions.
