ABSTRACT
with the global warming and the frequent occurrence of extreme weather, many roads and urban roads are often damaged by ice and snow under the low temperature, rain, snow and freezing climate. The problem of ice and snow pavement has been puzzling the road maintenance department. In this paper, from the point of view of active control of the temperature of asphalt concrete pavement, the mix design and mix-ture performance of phase change self regulating asphalt mixture are briefly described, and the effect of engi-neering application is tracked and monitored. The results show that the phase change material can improve the ability of asphalt mixture to deal with the change of environment temperature, keep the asphalt mixture in a good temperature range for a long time, not only play the role of snow melting and ice melting, but also avoid the early diseases such as low temperature cracks, effectively improve the safety of highway driving, and ex-tend the service life of pavement.
