掺盐化物沥青混合料路面抗凝冰性能试验研究
|
摘要
基于室内试验研究,分析了V-260盐化物抗凝冰沥青混合料的路用性能。结果表明:盐化物沥青混合料对金属无腐蚀性(盐化物主要成分为氯化钙),可用于桥梁结构表面铺装;试验段路面,在降雪天积雪能够很快融化且不产生冰冻,具有良好的抑冰雪效果。
The pavement performance of anti-freezing asphalt mixed with V-260 salt was analyzed by indoor tests. The result shows that,salt asphalt mixture is not corrosive against metal( the main composition of salt is calcium chloride),thus can be applied to surface paving for bridge structure. In the test section,the snow covered on the road in snowy days may melt soon without frost,presenting good ice suppression effect.
