Bitumen 80/100

Hiwa Oil Co, bitumen penetration grade 80/100 is used mainly as a paving grade, which is suitable for road construction, and maintenance. This grade of bitumen is normally used in the manufacturing of hot mix asphalt for pavement bases and wearing courses. Bitumen 80/100 is one of the other most used bitumen grades among all other bituminous products.

Penetration bitumen grade 80/100 is produce by process of vacuum Bottom (VB) and air in the reactor. And due to the control of the process conditions, we reaching to pure quality of penetration grade bitumen 80/100 which has a penetration between 80 to 100. The penetration grade bitumen 80/100 has a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This grade of bitumen 80/100 has strong viscosity and it’s widely used.

Guaranty and safety of penetration grade bitumen 80/100
