Bitumen 50-70
Bitumen Penetration Grade 50/70 is a premium paving bitumen derived from the vacuum distillation of crude oil. With medium hardness and excellent viscosity balance, this grade offers reliable performance in a wide range of pavement designs. It is one of the most widely used grades in road construction due to its optimal flexibility, resistance to deformation, and strong adhesion to mineral aggregates.
This grade is ideal for moderate climates and road surfaces exposed to regular traffic loading, ensuring long service life and enhanced durability.
