Penetration Bitumen 50/70
Penetration Bitumen 50/70 (Asphalt 50/70) , is a standard penetration grade Bitumen typically utilized as a Paving Grade Bitumen suitable for road construction and for the production of
Penetration Grade Bitumen 50/70
Product Overview
Penetration Bitumen 50/70 is a grade of paving bitumen with a penetration range of 50–70 dmm at 25 °C. It exhibits a balanced hardness and flexibility, making it suitable for a wide range of road construction and asphalt applications.
Because it performs well in both hot mix asphalt and pavement surfacing, this grade is widely used in highways, urban roads, industrial surfaces, and general infrastructure projects.
The Bitumen supplied by Peak Universal Business is petroleum grade bitumen, manufactured from fractional/vacuum distillation of crude oil. It is produced from vacuum residue (short residue) feedstock.
