Oxidized Bitumen 85/25 (Blown Bitumen 85/25) is a semi-solid and midrange grade of this category. Oxidized Bitumen R85/25 manufacturing is done by air blowing a soft type of bitumen, namely Penetration Bitumen 60/70.
This grade of penetration bitumen is the base and raw material for most bituminous products. The procedure under controlled conditions gives bitumen its more elastic properties compared to other types of bitumen.
The rubber-like property makes bitumen suitable to use in various industries and applications like construction, sealing, coating, road construction, etc.
