In winter and spring, asphalt pavement of highway in cold areas is exposed to snow and ice, which frequently causes traffic accidents. The hydrocarbon-based phase change energy storage particles developed in this project can keep the temperature of asphalt pavement above freezing point for an extended period of time, preventing the formation of snow or ice and ensuring road safety. It is a green and energy-saving technology with advantages of high energy utilization rate and less capital investment. In the future, this product can be widely applied on large-scale projects in highways in cold regions.
