摘要
路面的抗滑性能是保证车辆安全行驶的关键因素,盐化物融冰雪沥青路面的冻结抑制作用主要取决于路面内冻结抑制成分的含量及路面表面的盐分析出量。通过自然浸泡溶出量法研究盐分随时间的溶析规律,结果表明:盐化物的溶析分为三个阶段,初期溶析速度较快,第二阶段为匀速溶出阶段,后期溶液浓度趋于稳定,通过溶液浓度可间接评价融冰雪效果。
Anti-slip Performance of pavement is the key factor to ensure the safe driving of vehicles, anti-freezing effect of salt antifreezing asphalt pavement depends on the content of anti-freezing element in pavement and surface salt output. Through the natural immersion dissolved amount method to study the solventing-outlaw of salt with time, the results show that：dissolving salt can be divided into three stages, the initial dilution rate is fast, the second stage stripping stage is uniform, the late solution concentration tends to be stable, melting ice and snow effect is evaluated indirectly by the concentration of the solution.
