Analysis on the Application of Phase Change Materials in Winter Asphalt Pavement
The asphalt pavement is prone to frost and icing in the cold rain and snow climate in winter,resulting in a decrease in the anti-skid performance of the pavement and an increase in the accident rate,which has a serious impact on driving safety and pavement performance.Traditional passive snow removal methods are inefficient and require traffic lanes to affect the normal operation of roads,and chemical snow melting agents can cause soil and water pollution.Through literature research,this paper summarizes the common types of active snow melting ice pavement,analyzes the application research focus of phase change materials in asphalt pavement,and proposes to incorporate phase change materials into asphalt pavement in order to prevent or reduce the freezing disease of asphalt pavement in winter.
