Abstract

In general, air-blown asphalt can be made by several methods, which employ high temperature and pressure conditions. A new method, which not only can overcome this high temperature and pressure problem, but also can effectively produce air-blown asphalt within a short time, is to increase asphaltene content rapidly by adding a surfactant into an asphalt emulsion system under ultrasound. This method can produce different types of asphalt for various usages such as sol-gel type asphalt for the encapsulation of hazardous material and gel type asphalt for metal surface coating.
