Abstract：Adding photocatalyst into asphalt mixture can produce a new pavement material with the function of degrading automobile exhaust pollution. In order to study the effect of TiO2 content of photocatalyst on the performance of the mixture of drainage asphalt wear layer, a new type of pavement material was prepared by adding different dosage (0%, 30%, 50%, 70%) to the asphalt mixture instead of the mineral powder. The influence of TiO2 photocatalyst on pavement performance and surface function of asphalt mixture was studied through experiments.
