Oxidized Bitumen:
Oxidized Bitumen or Blown Asphalt or Blown Bitumen is produced by either Continuous or Staggered Blowing Process. ... Oxidized Bitumen or Blown Asphalt is produced by blowing hot air into the penetration bitumen. This action makes the bitumen rubberier than its original formula and it becomes harder bitumen.is used in the roofing and other (canals and tunnels, pipe coating)
Oxidized Bitumen is predominantly used in the piling industry as an anti-slip compound for the manufacture of under carriage sealants in the automobile industry. It is also used as a sealant compound, as a joint filling compound apart from being used in the manufacture of roofing felts and sound dampening felts
