Bitumen Penetration grade 10/20


Bitumen Penetration grade 10/20 is a kind of hard penetration grade bitumen which is provided during the process of oxidation of vacuum bottom the bitumen production that drives from distillation tower residue in vacuum oil refineries at bitumen production unit.
Bitumen penetration grade 10/20 ensures long-term savings because it allows for a thinner pavement design, which uses up to 30% less asphalt than traditional designs while ensuring extended pavement life.
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.

Application of bitumen penetration grade 10/20:

Bitumen 10/20 is suitable for road construction and repair for the asphalt pavements with superior properties.
This type of bitumen used in the manufacture of hot mix asphalt for bases and wearing courses and the bitumen 10/20 is also for production of pavements.
