Bitumen Grade 60/70

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.Penetration value is the vertical distance traversed or penetrated by the point of a standard needle into the bituminous material under specific conditions of load, time and temperature. This distance is measured in one tenths of a millimeter.

Penetration value test on bitumen is a measure of hardness or consistency of bituminous material. a 60/70 grade bitumen indicates that its penetration value lies between 60 & 70.
