Bitumen EN
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.
This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
Penetration Grade Bitumen supplied by Voptasch is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by Voptasch is produced from vacuum residue (short residue) feedstock.
Penetration Grade bitumen is specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumen has a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen.
