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。
路麵的抗滑性能是保證車輛安全行駛的關鍵因素，鹽化物融冰雪瀝青路麵的凍結抑製作用主要取決于路麵內凍結抑製成分的含量及路麵錶麵的鹽分析齣量。通過自然浸泡溶齣量法研究鹽分隨時間的溶析規律，結果錶明：鹽化物的溶析分為三箇階段，初期溶析速度較快，第二階段為勻速溶齣階段，後期溶液濃度趨于穩定，通過溶液濃度可間接評價融冰雪效果。

Anti-slip Performance of pavement is the key factor to ensure the safe driving of vehicles, anti-freezing effect of salt anti-freezing 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.
