Oxidized bitumen is mainly used for industrial purposes, such as roof insulation, flooring, industrial mastics, pipe coating, and paints. Oxidized bitumen is categorized based on softening points and penetration rate. For example, oxidized bitumen 85/40 is a type of bitumen whose softening point is 85±5 degrees Centigrade and its penetration rate is 40±5 dmm.
Oxidized bitumen is a specially treated form of bitumen, a byproduct of crude oil refinement. It undergoes an oxidation process that increases its viscosity, making it thicker and more resistant to temperature changes. This alteration enhances its adhesive properties and makes it ideal for various road construction applications.
As concerns about environmental sustainability grow, it's important to note that oxidized bitumen is recyclable. It can be reclaimed from old road surfaces and reused in new asphalt mixtures, reducing the demand for new bitumen and lessening the environmental impact of road construction.
