摘　　要：针对盐化物对防冰沥青混合料的性能影响进行研究。通过马歇尔试验、飞散试验以及贝雷法评价等确定临界盐化物用量;通过车辙试验与冻融劈裂试验等评价盐化物混合料的基本性能;通过多个浸水时段下的劈裂试验与冻结试验分析混合料的耐久性。结果表明:盐化物防冰沥青混合料无法持续保持短时段的防冻性能。The influence of salt on the performance of antifreezing asphalt mixture was studied. Through Marshall tests, scattering loss tests and Bailey method evaluation, the critical ratio of salt to aggregates was determined. Through rutting tests and freeze-thaw split tests, the basic performance of antifreezing mixture was also evaluated. Finally the durability of antifreezing mixture was analyzed through split tests and freezing tests under several soaking periods. The results show that the salt antifreezing mixture can not maintain performance of short-term antifreezing.
