Study on Properties of Modified Asphalt by the Thermoplastic Elastomer (TPE) Compound

Abstract:

In this study, the thermoplastic elastomer (TPE) material was prepared for modifing asphalt by premixing the water rubber powder and SBS. Effects of the raw material mass ratio on the properties of TPE modified asphalt were investigated. The experimental results indicated that the mass ratio of water rubber powder and SBS have more important effects on the penetration,softening point,and ductility, viscosity, high-temperature storage properties, elastic recovery and dynamic rheological properties of TPE modified asphalt.
