Bitumen penetration grade 10/20 means the penetration value is in the range 10 to 20 at standard test, Bitumen 10/20 is hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.

This Penetration Grade of 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.
