Definition of Bitumen Penetration Grade 10/20?

Bitumen 10/20 is a premium brand that is dark brown or black color similar to cement-shape semi-solid or viscous liquid form produced by the non-destructive refining of crude oil during petroleum refining. Penetration grade bitumen 10/20 has penetration between 10~20 desi-millimetre and the softening point between 58 ~ 66°C. The bitumen penetration grade 10/20 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. 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

 

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.
