VG-20 bitumen is a viscosity grade of bitumen used in cold climates and high altitudes. This grade of bitumen is suitable for road construction in regions where the average temperature is 30 to 37 °C.
In North India, VG20 is used for road construction in hot mix asphalt. The standard penetration value of VG-20 bitumen viscosity grade is 60 mm at 25 °C. The absolute viscosity of VG-20 bitumen is 1600 to 2400 poise at 60 °C.
