摘要
使用超薄盐化物自融雪沥青材料作为道路罩面不仅能够有效地清除路面积雪,降低路面维护成本,而且有效地延长了沥青路面的使用寿命。基于国内外研究现状,通过冰点降低机理解释了超薄盐化物自融雪沥青混合料(TSSAM)的融雪机理,分析了空隙率、温度、加水量与盐化物替代量等因素对TSSAM融雪性能与寿命的影响。运用灰关联熵分析法得出影响融雪性能与寿命的关键因素。采用回归分析得到融雪性能与融雪寿命的预估方程,为盐化物自融雪路面的研究提供了参考依据。
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 performance and snow melting life were obtained by using the gray correlation entropy analysis. Finally, the regression 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.
