Abstract

Asphalt is a kind of endothermic material. In summer, under continuous solar radiation, the working temperature of asphalt pavement is 25-30 degrees higher than the air temperature. On one hand it makes the urban heat island effect worse; on the other hand, it is also the main factor in rutting in freeways. Currently the main method of solving rutting problems of asphalt pavements is to increase high temperature stability of asphalt mixtures, but lowering the work temperature of asphalt pavement effectively is a new method of reducing the urban heat island effect and controlling the rut of asphalt pavement. This paper analyses systematically the feasibility of the technique of applying solar heat reflecting coatings. (a) For the covering entry of this conference, please see ITRD abstract no. E214938.
