导电沥青混凝土是一种非常理想的道路融雪化冰铺装材料,对沥青、集料和矿粉等原材料进行性能试验后,计算出矿质混合料的合成级配。通过对沥青混合料的试验和计算,得到基准油石比,并对导电沥青混合料的拌和顺序加以调整,完善了导电沥青混凝土的制备工艺。而后采用四电极法测量以各导电相材料掺量及油石比制备的导电沥青混凝土试件的电阻率,分别分析碳纤维、石墨掺量及油石比对电阻率的影响,得出了最佳导电相材料掺量和油石比范围。
Conductive asphalt concrete is a very ideal road snow melt ice paving materials, asphalt, aggregates and slag and other raw materials for performance testing, calculate the composition of mineral aggregate gradation. Through the test and calculation of asphalt mixture, the reference ratio of stone is obtained, and the mixing order of conductive asphalt mixture is adjusted, and the preparation technology of conductive asphalt concrete is improved. After that, the resistivity of the conductive asphalt concrete specimens prepared by mixing the conductive phase materials and the ratio of the oil-to-gas phases was measured by a four-electrode method. The influence of the carbon fiber, the graphite content and the ratio of the oil to the stone on the resistivity was analyzed. Material dosage and oil to stone ratio range.
