  • Penetration Grade

Penetration Grade Bitumen or Paving Grade Bitumen is a standard bitumen known as a crucial element for road construction and for the production of asphalt with superior qualities, which is very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix. This grade of Bitumen is mainly used in the production of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen supplied by Gayatram Pte Ltd  is petroleum-grade bitumen, manufactured from fractional / vacuum distillation of crude oil.
