Understanding Oxidised Bitumen

What is Oxidized Bitumen

Oxidized Bitumen producing process

Oxidized bitumen is blown from blowing hot air to pure bitumen at the final stage of the purification operation In this process, hot air with a temperature of 200 to 300 degrees Celsius is blown through a perforated tube into a compartment containing bitumen.

As a result of this process, the hydrogen atoms in the bituminous hydrocarbon molecules are combined with air oxygen and the polymerization takes place with the formation of water

Oxidized bitumen penetration is lower than that of pure bitumen

Oxidized bitumen  has a higher degree of softness and a lower sensitivity to temperature variations This type of bitumen is used to make roofing sheets, car tires and lining.

Oxidized Bitumen grades like 80/25 bitumen means blown bitumen with degree of softness 80  and a degree of penetration is 25

Oxidized Bitumen uses
