Viscosity Grade Bitumen is mostly used as a Paving Grade and it’s suitable for Road Construction and for the Asphalt pavements producing with premier attributes. Viscosity Grade Bitumen is usually used in the production of Hot Mix Asphalt.

Viscosity Grade Bitumen has a thermoplastic feature which causes the material to Soften at High temperatures and to Harden at Lower temperatures. This temperature viscosity relevance is significant when specifying the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen. In the Viscosity Grade Bitumen Specifications, the most important emphasizes is based on the Bitumen ductility.
