What is Oxidized BitumenOxidized Bitumen producing processOxidized 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 waterOxi …
