Oxidized Bitumen is a type of Bitumen that obtains from blowing air to the Pure VB (vacuum bottom) Bitumen. Oxidized Bitumen has a lower penetration point and more softening point in comparison to VB. Based on its softening point and penetration points, it classifies into three types of low, medium and hard Oxidized Bitumen.
Oxidized Bitumen is well known by other names also as Blown Bitumen, Hard Bitumen, Blown Asphalt, and Oxidized Asphalt.
