Blown Asphalt is a bituminous product with excellent elasticity, which is made from of bitumen as its main material by injecting air at high temperature, 220~250 to cause polymerizing and condensing reaction. It has more Asphaltic and less Petroleous than Straight Asphalt; therefore, it has excellent heat-proofing, strong crash-proofing and lower thermo-sensitivity
