Bitumen 80/100

Bitumen 80/100

Bitumen 80/100 is a softer penetration-grade bitumen with a penetration value of 80–100 (measured in 0.1 mm). It is widely used in colder climates for road construction, asphalt production, and maintenance. Its flexibility and adhesive properties make it suitable for areas where lower temperatures demand a softer binder.

Bitumen 80/100 is a penetration-grade bitumen widely used as a binder in asphalt mixes for road construction, especially in areas with colder climates. Its softer consistency makes it more adaptable to low-temperature conditions, reducing the risk of cracking and enhancing road durability.
