What Is Oxidized Bitumen?
Oxidized Bitumen or Blown bitumen grades are produced by passing air through the penetration grades. This process results in more rubbery property of the bitumen than its original formula and they are simply harder bitumen. When tempered by controlled temperature, hard bitumen is widely used as an anti-slip layer compound in the piling industry, production of roofing felts, roofing and waterproofing industries, sound dampening felts and carriage sealant in the automotive industry, electric cable joint protection, joint filling compound, sealant compound and many others. It is also used in sealing saw cuts and joints where expected movements are minimum. It is also used in the manufacturing of bituminous marine mastic for the oil & gas pipeline joints.
