Cutback Bitumen Exporters

Slow Curing – Medium Curing – Rapid Curing

Cutback Bitumen dissolved in a solvent. Typical solvents include Naptha, Gasoline and Kerosene, White Spirit etc. The type of solvent controls the Curing time while the amount determines the Viscosity of the Cutback Asphalt. This is done to reduce the Viscosity of the Bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat bitumen. The materials used to cutback bitumen will evaporate after application to leave the remaining material similar in hardness to the original bitumen.

Difference between Bitumen Cutback and Bitumen Emulsion
The advantage of Cutbacks over Emulsions is a much higher residual Bitumen percent, typically over 80% compares with over 40-65% for Bitumen Emulsions. The result, more Bitumen left on the roadway after curing, for the same volume of binder applied.

Cutback Asphalt Bitumen Classifications
Cutback Bitumen divided into three classifications, Slow-Curing (SC), Rapid-Curing (RC) and Medium-Curing (MC) depending on the solvent used. They are further defined by Grades which indicates the minimum kinematic viscosity (fluidity) of the cutback.

Tiger Cement Limited has the capability to Export and Supply the different Grades of Cutback Bitumen in compliance with National and International standards.
