This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
What is the difference between bitumen 60 70 and 80 100?
The difference between 80/100 and 60/70 penetration grade is the penetration range. Bitumen 60/70 has lower penetration which means it is harder than bitumen 80/100. To the contrary of bitumen 80/100, Bitumen 60/70 is suitable to be used in hot climates and it shows more durability exposing to heavy traffic loads.
