为研究超薄盐化物自融雪沥青混合料的融雪性能，以溶液电导率作为评价指标来表征溶液中盐分浓度大小，间接评价自融雪沥青混合料的融雪化冰效果。采用灰熵法分析不同影响因素对融雪性能的显著性，并对其融雪机理进行探讨。结果表明：盐化物替代量越大，融雪性能越好；随着溶析时间的延长，沥青混合料空隙率对融雪性能影响程度减小；随着加水量的增大，沥青混合料融雪性能逐渐衰减；盐化物替代量是影响沥青混合料融雪性能的最主要因素。研究成果为超薄盐化物自融雪沥青混合料的材料组成设计提供了有益参考。
In order to investigate on the snowmelt performance of ultra-thin saline and self-melted asphalt mixture,the solution conductivity as evaluation index to represent salt concentration in the solution size, since the snowmelt asphalt mixture indirect evaluation effect of snow melting of the ice. Grey entropy method was used to analyze the effect of different factors on the properties of snow melt significantly,and its snowmelt mechanism was discussed. The results show that the greater the amount of saline content alternative,the better the performance of melting snow. As the extension of dissolving analysis time,air void of asphalt mixture performance of snowmelt influence degree decreases. With the increase of water added,asphalt mixture snowmelt performance attenuation gradually. Saline content replacement is the main factors influencing the performances of asphalt mixture of snowmelt. The research results for the ultra-thin saline and self-melted asphalt mixture composition design provides a useful reference.
