Bitumen 75/25
Oxidized bitumen 75/25 has a softening point of about 75°C and a penetration of about 25 dmm. It balances heat resistance with enough flexibility for waterproofing and sealing work.
Where Bitumen 75/25 is used
Oxidized (air-blown) bitumen is made by blowing air through hot bitumen, which raises its softening point and makes it far less sensitive to temperature. Grades are named softening point / penetration, so 90/15 means a softening point around 90°C and a penetration around 15 dmm.
