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 RDR Energy is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by RDR Energy is produced from vacuum residue (short residue) feedstock. Penetration Grade bitumen are specified by the penetration and softening point test. The penetration grade bitumen have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/viscosity relationship is essential when determining the performance parameters such as the a
