Definition of bitumen penetration grade 80/100

 

Bitumen Penetration Grade 80/100 is a standard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. 

Bitumen penetration grade 80/100 is one of the most used bitumen grades and it’s a basic material for all other bituminous products.

 

Application of bitumen penetration grade 80/100

The main usage of bitumen penetration grade 80/100 is in road making at cold regions. Since the penetration grade bitumen 80/100 is a soft bitumen, it is more suitable for soils with high particle density such as clay. Because they have a smaller size and the bitumen 80/100, as a soft bitumen, can easily penetrate them.

On the other hand, high penetration graded bitumen works better for soils with low particle density.
