The use of ultra-thin salinity from the snow melting asphalt as a road cover can not only effectively remove the road snow and reduce road maintenance costs, but also effectively extend the use of asphalt pavement life. Based on current researches in China and abroad, the mechanism of snow melting by TSSAM was explained in this paper, and the effects of mechanism of porosity, temperature, water and salt substitution and other factors on the snowmelt performance of TSSAM were analyzed. Then, the key factors influencing the snow melting per- formance and snow melting life were obtained by using the gray correlation entropy analysis. Finally, the regres- sion equation was used to obtain the prediction equation of snow melting performance and snow melting life. This paper provides reference for the research of salinized snow surface.
