Air blowing: The manufacturing process in which air is blown through an asphalt flux to make oxi-dized roofing asphalts. An exothermic oxidation reaction occurs, yielding an asphalt that is harder, more viscous, less volatile, and less temperature-susceptible than the asphalt flux used as the feedstock to the process.

Roofing 101 – Part Three Asphalt magazine

Air blowing is the process of passing air through heated asphalt to raise the softening point of the asphalt while maintaining much of its flexibility at lower temperatures. In a conventional batch oxidation process, the flux enters a pre-heater at approximately 121-149°C (250-300°F) and is heated to and maintained at 232-260°C (450-500°F) entering the oxidation still.

Although similar in many respects to the normal paving grades of asphalt cement previously discussed, the blowing process provides materials that soften at higher temperatures than asphalt cements. Because the higher softening point is a most important and desirable property of blown asphalts, they are usually classified in terms of the ring and ball softening point test, rather than viscosity ...
