Overview – VG20 Viscosity Grade Bitumen
VG20 Bitumen is a medium-viscosity paving grade, ideal for road construction projects in moderate to hot climates. The “VG20” designation indicates its viscosity characteristics at 60°C, making it suitable for bituminous mixes, hot mix asphalt production, and surface dressing in regions that experience significant temperature variations. Compared to VG10, VG20 offers better stiffness and strength, making it a preferred choice for more heavily loaded roads and infrastructure projects.
Technical Classification and Viscosity Testing
Viscosity Grade Bitumen is classified based on its resistance to flow at specific temperatures. VG20 is tested using instruments like the Brookfield and Saybolt viscometer, following national and international standards such as IS:73 and ASTM D2171. With greater resistance to deformation under high traffic loads, VG20 ensures long-lasting pavement performance and reduces susceptibility to rutting, especially in warmer climates.
Applications and Key Advantages
VG20 is widely used in manufacturing hot mix asphalt for highways, urban roads, and airports. It is particularly effective in mechanized paving and applications where durability, cohesion, and controlled viscosity are critical.
