Penetration Grade
Performance Grade (PG) Bitumen is bitumen which is graded based on its performance at different temperatures. The LTPP has given the certain algorithm to calculate the temperature of the pavement based on the temperature of the air above. From this, the highest and the lowest temperatures of the pavement is calculated and the bitumen that performs well in that temperature range is selected.

Viscosity Grade Bitumen (Asphalt) is a Bitumen grade mostly used as a Paving Grade and it’s suitable for road construction and for the asphalt pavements producing with premier attributes. VG Bitumen is usually used in the production of hot mix asphalt.
Viscosity Grade Bitumen is petroleum grade bitumen, which produced from fractional vacuum bottom which comes from distillation of crude oil, which feasible appliance and behavior changes according to its temperature.
Australian Grade
Australian Grade
Bitumen Classification Paving grade Bitumens are categorized 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 exceptional waterproofing and adhesive properties.
Bitumens used in road construction and maintenance are refined and blended to meet strict road engineering requirements and industry specifications.

Asphalt Cement Grade of bitumen is one of the main categories of viscosity grade bitumen.
With AC grading, asphalt binder is specified by properties it possesses before it undergoes HMA making process. Asphalt binder samples Viscosity of standard bitumen measured at 60 ºC (the maximum pavement temperature).
