AT Cutback Bitumen is made up of penetration grade bitumen dissolved in a petroleum solvent to reduce viscosity for ease of handling and application. Upon exposure to atmospheric condition, the solvent evaporates and leaves the bitumen film to perform its function as a binder for aggregates. In applications where the aggregates are damp, AT Cutback Bitumen can be also customised with adhesion agents added to suit the condition.

AT Crack Sealant is a cold-poured, polymer-modified emulsion specially made for crack treatments on bitumen surfaces, in particular roads. The purpose: to create a water tight barrier in order to extend surface life by preventing or substantially reducing the infiltration of water into the surface structure.
AT Penetration Grade Bitumen (AT Pen 60/70 & AT Pen 80/100) is widely used in road and airport constructions and other similar applications. It is obtained from the vacuum distillation of an atmospheric residue derived from crude oil.
