Bitumen Classification Bitumen classification is according to viscosity (degree of fluidity) gradings. The higher the grade, the stiffer the bitumen. Most high performing roads in Australia are built and maintained using bitumen because it is durable and has...

Polymer Modified Bitumen Description Bitumen has been used for thousands of years and its importance as a valued engineering material continues to increase. The interest in the modification of bitumen using polymers, whether virgin, scrap, or polymer blends, is...

Performance Grade Bitumen Description The performance grade bitumen is based on the evaluation of the material performance when in use, unlike being rational as in the viscosity grading system. The viscosity grading system is more into the experience-based...

Viscosity Grade Bitumen Description Traditionally, paving bitumen have been specified in terms of their penetration, but the measurement of viscosity provides a more accurate method of specifying binder consistency and a more effective method of determining the...

Penetration Grade Bitumen Description Pentration / Paving Grade Bitumen is Bitumen classified using the penetration property. Penetration grading’s basic assumption is that the less viscous the asphalt, the deeper the needle will penetrate. Bitumen which is...
