Description
Definition of bitumen penetration grade 10/20
It 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. RABIT exporting bitumen 10/20 its penetration hard grade and softening between 10 to 20. RABIT bitumen 10/20 is hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with the below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
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.
