摘要
本研究的目的是对氯化物基沥青混合料的长期融冰雪性能进行评价。通过自然浸泡法和加速浸泡法,采用比重计测量盐溶液的密度,从而计算盐分溶出量。结果表明,两种方法都有类似的趋势,满足对数关系式;与自然浸泡试验相比,加速浸泡试验更有效、更省时,在60℃时析出最快;提出了氯化物基沥青混合料长期融冰雪性能的预估模型。
The purpose of this study is to evaluate the long-term anti-icing performance and moisture susceptibility of chloride based asphalt mixture. By natural soak method and accelerated soak method,the density of salt solution was measured by the hydrometer, then the amount of salt dissolved was calculated,The results showed that the two methods had similar trend and met logarithmic relation. Compared with natural soak test, accelerated soak test was more effective and time-saving, and it precipitated most rapidly at 60 ℃ .A prediction model for long-term anti-icing performance and susceptibility of chloride based asphalt mixture is proposed.
