摘要

为研究工程实际中融雪剂对道路抗滑性能的影响,对低温条件下撒布融雪剂路面的摩擦系数衰减率进行了试验与分析。首先提出了通过测定低温环境中撒布融雪剂前后路面抗滑值,进而计算路面抗滑衰减率的试验方法;然后测定了不同环境温度、使用浓度、融雪剂种类、试块类型条件下的融雪剂路面抗滑衰减率;最后分析了不同因素对路面抗滑性能的影响规律与显著程度。结果表明:随着环境温度的降低、融雪剂使用浓度的不断增加,融雪剂会使路面抗滑衰减率不断增大;不同种类的融雪剂对路面抗滑性能的影响有着显著差异。
        In order to study the effect of deicers on the anti-slip performance of road,the friction coefficient of pavement under low temperature conditions is tested and analyzed.Firstly,the test method that the attenuation rate of pavement friction coefficient under low temperature conditions is calculated by measuring pavement friction coefficient before and after spraying deicers is proposed.Then,the attenuation rate of pavement friction coefficient is measured for deicers under different ambient temperature,concentrations,types of deiciers and asphalt concrete test block.Finally,the influence rules and impact degree of different factors on skid resistance of pavement are analyzed.The results show that,with decreasing of the ambient temperature and increasing concentration of deicer,the attenuation rate of pavement friction coefficient is increased.The effect of different types of deicer on the anti-slide performance of pavement is significantly different.
