石墨钢纤维碳纤维导电沥青混合料配合比优化

The mix design of graphite steel and carbon fiber modified conductive asphalt mixture

寒冷地区路面积雪结冰为公路安全运营构成极大威胁。研究以最佳方式快速、高效、无污染的方式清除路面冰雪,在沥青混合料中以一定比例掺入石墨、钢纤维及碳纤维等导电材料,通过室内对比试验确定各材料的最佳掺入量,实现提升沥青混合料导电性能,通过导电路面升温清除路表冰雪,在我国北方公路绿色环保清冰除雪、延长路面使用寿命方面具有一定参考意义。

Snow and ice on roads in cold region presents a great threat to road safety.The best,fast,efficient and pollution-free way to clear the road ice and snow is studied.The main method is that graphite,steel fiber and carbon fiber conductive material are doped into the asphalt mixture with a certain proportion.Then by the experiments the optimum adding amount of each material is determined.The research result can improve asphalt mixture conductivity,by raising the temperature of pavement surface to clear road snow and ice,and the result can present the reference to prolong the service life of pavement on the highway in the north of China.
