沥青路面因降水或冬季雨雪结冰变得湿滑,会严重威胁车辆行驶的动力性及安全性。研究提高路面冬季防冻及抗滑性能的关键技术势在必行。采用以SMA沥青混合料作路面磨耗层、发热管加热系统融雪化冰、温控介质调控温度的研究思路和技术途径,有望制备出能够自动加热融雪除冰,防冻抗滑功能兼备的沥青路面。
pavements will be wet and sliding under the situation of rain or ice, which will seriously threat the power and security of vehicle driving. It is imperative to study the key techniques of improving the anti-sliding property of pavements in winter. Within the study ideas and technical methods of adopting SMA asphalt mixture as wearing course, introducing a heating system consists of heating pipes to melt snow and ice, and using a kind of temperature controlling media to control temperature, we are promising to produce a kind of pavement which can auto-heating to melt snow and ice and has both properties of freeze resistance and anti-sliding.
