Bitumen VG20 is a Viscosity Grade bitumen which is specified by ASTM Standard D3381-09 and AASHTO M226-80 (2008). VG Bitumen specifications cover by Viscosity at 60 ̊C (140 °F).
Application of Bitumen Viscosity grade VG 20
VG-20 is used for paving in cold climate & high altitude regions. Viscosity Grade Bitumen (Asphalt) VG20 is a Bitumen grade mostly used as a Paving Grade and it’s suitable for road construction and for the asphalt pavements producing with premier attributes. VG Bitumen is usually used in the production of hot mix asphalt.
