摘　　要：防冰沥青混合料是一种具有主动防冰效果的沥青混合料,为研究防冰沥青混合料的路用性能及防冰效果,采用常规的试验方法研究防冰沥青混合料的路用性能,采用研发的防冰冻试验、拉拔试验和除雪试验对比评价普通沥青混合料和防冰沥青混合料的防冰效果,分析防冰沥青路面的耐久性。室内研究结果表明防冰沥青混合料在原材料和级配符合使用条件下,具有较好的实际路用性能和防冰效果。在室内研究的基础上,铺筑了试验路,通过试验路使用性能的观测,验证了防冰沥青混合料具有较好的防冰效果。Anti-icing asphalt mixture is an asphalt mixture with active anti-icing effect. In order to study its pavement performance and anti-icing effect, conventional test method is used to study its pavement performance, the developed anti-freezing test, pull-out test and snow removal test are used to comparative evaluate the anti-icing effects of ordinary asphalt mixture and anti-icing asphalt mixture as well as analyze the durability of anti-icing asphalt pavement. The indoor research results show that the anti-icing asphalt mixture of appropriate materials and gradation has good pavement performance and anti-icing effect. On the basis of the indoor study, the experiment road sections are paved, and the good anti-icing effect are proved by performance observation of experiment sections.
