Cutback Bitumen

Ratings
(0)

Cutback bitumen is a form of bitumen that has been thinned with solvents to reduce its viscosity, making it easier to apply at lower temperatures.

 

- Types:

  - Rapid-Curing (RC): Contains volatile solvents like naphtha, evaporating quickly. Used in tack coats and surface treatments.

  - Medium-Curing (MC): Contains less volatile solvents, ideal for prime coats.

  - Slow-Curing (SC): Contains non-volatile solvents, used in road construction and repair.

- Benefits: Cutback bitumen is particularly useful in cold climates where standard bitumen would be too viscous to apply. It’s also suitable for quick-setting applications.
