| 摘 要： | 主要研究融雪盐对路面材料的影响。首先进行普通沥青、SBS改性沥青、胶粉改性沥青材料室内冻融循环试验,对冻融循环后的各种沥青进行改进的黏附性试验,分析沥青与粗骨料黏附量随冰冻温度、融雪剂浓度和冻融循环次数等因素的变化规律。结果表明：融雪盐环境对沥青的黏附性会产生较大影响,其中冻融循环次数是最大影响因素。

| Abstract: | After salt freezing circulation test was completed, temperature reacting performance, high and low temperature performance and the adhesive influence of coarse aggregate with matrix asphalt, SBS modified asphalt and rubber powder modified asphalt was respectively analyzed according to the prin- ciple of the orthogonal experiment. The effect and tendency of different freezing temperatures, the presence of snowmeh agent and its concentration and freezing-thawing circulations was concluded. The results show that the greater the number of freezing-thawing cycles is the largest factor. |
