Asphalt produced by blowing air via molten asphalt held at an elevated temperature. This process is used to modify properties of the asphalt. The physical properties of asphalts may further be modified by 'air blowing'. This is an oxidation procedure which entails the blowing of air through the asphalts, either on a batch or a continuous basis, with the short residue at a temperature of 240°C to 320°C.
