Penetration Grade Bitumen is a standard bitumen commonly used as a Paving Grade Bitumen in road surfacing, 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.
All Penetration Grade Bitumen supplied by Buoyancy Impex Pvt Ltd are petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil produced from vacuum residue (short residue) feedstock. Penetration Grade bitumen are specified by the penetration and softening point test.
Uses:
Bitumen 60/70 is also used to Manufacture Bitumen mix, hot asphalt mix for bases and wearing courses, cutbacks, Emulsions and Modified Bitumen.
