VG 20 bitumen

Viscosity 20 bitumen VG-20 is commonly used in areas with cold climates or high elevations. Road construction with this grade of bitumen is appropriate for regions whose average temperature is between 30 and 37 °C. Hot mix asphalt is typically made from VG20 in North India. Viscosity grade VG-20 penetration is 60mm at 25 °C as a standard. A viscosity of VG-20 bitumen at 60 degrees Celsius ranges between 1600 and 2400 poise.

Bitumen VG 20 formulation

This Bitumen VG 20 formulation is widely used for spraying applications, including surface-dressing and paver applications for cold climates and high-altitude regions. In addition, it is used in asphalt emulsions and modified asphalt. As a hot mix asphalt base course and wear course, this grade of bitumen is most commonly used.
