Description
Cutback Bitumen RC-70 is a CUTBACK BITUMEN Rapid Curing which containing 55% bitumen. This bitumen is black in color and is produced under the ASTM D 2028M standard. RC-70 is a widely used product in road construction and maintenance. It is a type of bitumen that has been dissolved in a petroleum solvent, making it easier to handle and apply.
Applications of CUTBACK BITUMEN RC-70
The use of quick-setting soluble bitumens is mostly in the field of protective asphalts:
- One-layer surface asphalt
- Multi-layer surface asphalt
- Sealing coating with stone materials
- Also, these bitumens are used in the area of pervious macadam asphalt with a lot of free space
