General of Cutback Bitumen

Cutback bitumen is produced by adding petroleum distillates, such as kerosene. This action reduces the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successfully sprayed sealing with neat bitumen. The materials which added to bitumen will vaporize after application to leave the remaining material similar in hardness to the original bitumen.

Cutback Bitumen Uses

The process of prime coat involves using a low viscosity binder to a prepared. It is planned to be absorbed by the top layers of the base and provide a surface more easily wetted by a subsequent bitumen covering.
