PENETRATION BITUMEN 40/50
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. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
Grades of penetration bitumen:
The most popular grades are; grades 40/50, 60/70, 80/100, 85/100 and 100/120. We are also capable of producing other grades of Penetration Bitumen upon request by our customers
