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
PENETRATION BITUMEN 60/70
The bitumen is provided during the process of oxidation of vacuum bottom in bitumen production units. Due to its medium air blowing and penetration, it is used in mild areas.
Bitumen penetration grade 60/70 is semi hard penetration grade bitumen used as a paving grade bitumen which is suitable for road construction and repair. It is also used for the production of asphalt pavements with the below technical specification. This grade of bitumen is mainly used in the manufacturing of hot mix asphalt for bases and wearing courses. Bitumen 60/70 is one of the most used bitumen grades and it’s a basic material for all other bituminous products.
