Study on Anti-Icing Effect and Long-Term Maintenance Mechanism of Slow-Release Anti-Freezing Mixture Pavement
[Purposes]This paper aims address the traffic safety issues caused by bridge decks being prone to freezing during winter ice and snow weather,it is necessary to conduct research on slow-release anti freezing asphalt mixtures.[Methods]This article compares and evaluates the short-term ice melting and long-term anti icing effects of SMA-13 domestic and SMA-13-MFL through melting tests,tear tests,and conductivity tests.[Findings]The research results show that the melting test shows that the melting ability of imported MFL anti freezing agent is better than that of domestic anti freezing agent.The tear test shows that the melting performance of domestic anti freezing agents is better than that of im-ported MFL anti freezing agents.The salt thawing conductivity test shows that the precipitation rate of im-ported MFL antifreeze is higher than that of domestic antifreeze;the imported MFL anti freezing snow melting and deicing effect can last for 2～3 years,while the domestic anti freezing agent′s snow melting and deicing effect can last for 3～4 years.[Conclusions]The slow-release anti freezing mixture has good prospects for promotion and application in bridge deck pavement.
