Softening point / penetration

Oxidized Bitumen

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.
