Oxidized bitumen is extensively utilized across various industrial applications, including roofing insulation, flooring materials, industrial mastics, pipe coatings, and paints. It is classified based on softening points and penetration rates. For example, oxidized bitumen designated as 85/40 features a softening point of 85 degrees Celsius and a penetration rate of 40 dmm.

This material is specifically engineered to mitigate weight loss when exposed to elevated temperatures. Its softening point is considerably higher than that of conventional bitumen, resulting in reduced thermal sensitivity. Additionally, the penetration index (PI) of oxidized bitumen surpasses that of bitumen typically employed in road construction, where the PI ranges from 2 to 8 due to the gel-like structure formed by asphalt accumulation. Hence, oxidized bitumen remains an essential component in various applications requiring enhanced durability and thermal stability.
