为了确定碳纤维导电沥青混合料的合理碳纤维掺量,选用短切聚丙烯腈（PAN）基碳纤维作为导电相材料,通过大量室内试验分析了碳纤维掺量对导电沥青混合料AC-13C的马歇尔性能和导电性能的影响,并验证了其路用性能。结果显示,相同油石比下,随着碳纤维掺量的增加,导电沥青混合料的毛体积密度、沥青饱和度和马歇尔稳定度呈先增后减的变化趋势,空隙率和矿料间隙率呈先减后增的变化关系,而流值一直增大。通过对碳纤维掺量不同范围的沥青混合料分别采用AC、调整和SMA的技术标准,确定了合理的最佳油石比,且最佳油石比与碳纤维掺量之间呈良好的半对数相关关系。同时,在最佳油石比下,导电沥青混合料电阻率的...

In order to determine a reasonable carbon fiber contents for the conductive asphalt mixture with carbon fiber, the chopped polyacrylonitrile (PAN) based carbon fiber was selected as a conductive phase material. Many laboratory experiments were conducted to analyze the effect of the carbon fiber contents on the Marshall performances and the conductive performances for the AC-13C of conductive asphalt mixture and then verify its pavement performances. The results show that, under the same asphalt-aggregate ratio, with the increases of the carbon fiber contents, the bulk volume density, the voids...
