Research on Application Technology of TLA Modified Asphalt Mixture

Abstract:

Marshall test design methods are used to design TLA modified asphalt mixture and base asphalt mixture respectively, and their pavement performance is tested. The results showed that there is a transforming coefficient of 1.10 between optimum asphalt content (OAC) of 25% TLA modified asphalt mixture and that of base asphalt mixture, and TLA modified asphalt mixture has excellent high temperature stability, capacity of moisture-resistance damage and impermeability. Construction technology of TLA modified asphalt mixture is similar to that of ordinary asphalt mixture, but the key for it is to control construction temperature, uniformity and compactness of TLA modified mixture.
