Bitumen 40-50
Bitumen Penetration Grade 40/50 is a high-quality, semi-hard paving bitumen obtained from the vacuum distillation of crude oil. With a lower penetration range compared to softer grades, PG 40/50 offers high durability, excellent resistance to deformation, and superior performance under heavy traffic loads.
This bitumen grade is widely used in hot climates and regions with high axle load conditions due to its high stiffness and outstanding adhesive properties with mineral aggregates.
