Puma Bitumen supplies a full range of paving-grade bitumen products that comply with the Australian Standard AS 2008, commonly referred to as Class Bitumen. This system grades bitumen based on its viscosity at 60°C, providing predictable handling, application, and long-term pavement performance.

Whether used in hot mix asphalt or sprayed sealing, our AS Class binders deliver consistency across Australia’s diverse climates and traffic conditions.

Penetration Grade Bitumen is one of the most widely used bitumen types globally, particularly across Europe, the Middle East, Africa, and parts of Asia. It is classified based on the depth a standard needle penetrates the bitumen sample under specific conditions — an indicator of hardness or softness.

Typical grades include 40/50, 60/70, 80/100, with the numbers representing the penetration range in tenths of a millimetre.

Performance Grade Bitumen, often referred to as PG bitumen, is used extensively in North America and parts of the Middle East. This grading system classifies bitumen based on its performance under a range of climatic and loading conditions, with designations such as PG 64-10, PG 70-22, and PG 76-22.

The numbers reflect the high and low pavement temperatures (in °C) the binder is designed to withstand without failure.

Viscosity Grade Bitumen is commonly used in India and Southeast Asia. This classification measures the viscosity (thickness) of the bitumen at specified temperatures, providing a more accurate indication of how it behaves during mixing and laying compared to older penetration methods.

Typical grades include VG10, VG20, VG30, VG40, where higher numbers indicate higher viscosity and stiffness.
