Cutback Bitumen SC
The industry is sometimes in need of low viscosity bitumen. There manufacturers came to a solution to deliver cutback bitumen which is a low viscosity liquid dissolved in a solvent. The main advantage of this type of bitumen is that there is no need to heat it before using.
Cutback bitumen is made by the addition of controlled amounts of petroleum extracts such as kerosene, naphtha, diesel oil, and furnace oil to perform as a solvent.
Although these adhesive materials are added to lessen the need for heating before using, they will evaporate as the bitumen is applied. This process is done for a temporary reduction of the bitumen viscosity.
Cutback bitumen is more appropriate for cold regions than the others. Primer sealing and sprayed sealing are some items for which cutback bitumen is suitable.
