摘　　要：设计导电沥青混凝土导电性测试方案,分别对石墨、碳纤维、铜纤维等导电相材料进行室内对比试验研究,材料含量不同对导电性影响也不相同。试验结果显示,随着石墨含量的增加,可明显降低混凝土电阻率,但超过15%后,电阻率改善效果趋缓;随着碳纤维、铜纤维含量及长度的增加,混凝土导电性得到改善。研究成果可为我国北方地区导电沥青混凝土路面的材料组成设计提供参考借鉴。The electric conductivity test of conductive asphalt concrete was designed.By comparing the conductive materials such as graphite,carbon fiber and copper fiber,the test of the influence of different contents on the conductivity was carried out.The result shows that the electrical resistivity of concrete can be reduced obviously with the increase of graphite content,but the resistivity improvement effect slows down when the content of graphite exceeds 15%.With the content and length increase of carbon fiber and copper fiber,the conductivity of concrete is improved.The result of the experiment can provide reference for the material composition design of conductive asphalt concrete pavement in northern China.
