Petroleum asphalt is oxidized and then converted into oxidized bitumen 95 25 without adding catalysts. The material obtained from such processes has a much higher penetration index because it is done at high temperatures. It is used to bond roofing membranes.
The petroleum bitumen 95 25 is produced by blowing bitumen 60/70 with high temperatures and is composed of petroleum bitumen. 95 25 is the designation of the semi-softening point acceptance criteria for oxidized bitumen.
Bitumen oxidized undergoes a chemical reaction such that it turns from a solid to liquid after heating. In contrast, oxidized bitumen grades are created by passing a controlled amount of air through soft bitumen while under temperature control. Compared to penetration and hard grade bitumens, this bitumen has more rubbery properties, and it is utilized for a variety of industrial applications.

Bitumen 95 25 oxidized is widely used in a wide variety of industries as a slip-resistant layer compound, such as in the piling industry, in the roofing and waterproofing industries, in sound dampening felts, undercarriage sealants, and for electric cable joints. Among them are adhesives, carpet backing, corrosion protection, acoustic panels, chemicals, fuel, paint products, and sealant compounds. This compound is also used to seal saw cuts and joints where movement is expected to be minimal. Bituminous marine mastic is also manufactured for pipeline joints in the oil and gas industry.
