Penetration Grade Bitumen
Bitumen penetration grade is a commonly used standard grade of bitumen for pavement across the world. It is classified based on its penetration number, which determines its hardness. Known as paving grade bitumen, PEN grades are categorized based on the depth that a laboratory needle penetrates them, including 40/50, 60/70, 80/100, and 85/100. Bitumen 85/100 is the softest, while 40/50 is the hardest on the PEN grading scale

Viscosity grade bitumen
The VG grading system was developed by the Bureau of Indian Standards (BIS) and is widely used in India. It is classified based on its viscosity, measured in centistokes at 60°C.
The VG grading system includes VG 10, VG 30, VG 40, and VG 50. The higher the VG number, the more viscous and stiffer the bitumen. Viscosity is an important factor in determining the performance characteristics of VG bitumen, including its resistance to deformation, fatigue, and cracking under traffic and environmental loads.
