Oxidized (Blown) Bitumen 85/25

Oxidized bitumen R85/25 has a softening point of 85 and its penetration grade is 25. Among all types of oxidized bitumen, this bitumen is widely used and very popular in the market.

How does this bitumen produce?

Bitumen of this type is derived from the blowing hot air with the temperature of 200 to 300 degrees Celsius to the penetration grade bitumen inside the BBU of the refinery.
