Penetration Grade Bitumen

Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it’s very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.

Definition of bitumen penetration grade 60/70 Bitumen penetration grade 60/70 means the penetration value is in the range 60 to 70 at standard test conditions which commonly used as a Paving Grade. Bitumen is applicable for the production of hot mix asphalt for bases and pavements and for road construction.
