Oxidized (Blown) Bitumen 85/25
Oxidized Bitumen 85/25 is a premium-grade, thermally modified bitumen engineered through a controlled air-blowing process. This advanced oxidative treatment transforms standard bitumen into a robust material with enhanced adhesion, thermal stability, and longevity. The designation “85/25” indicates a high softening point of approximately 85°C along with a balanced penetration value of 25 dmm. Together, these properties yield a product that excels in environments subject to extreme temperature variations and mechanical stresses.
