基于融雪效果的导电沥青路面电极优化设计

Optimal design of conductive asphalt pavement electrode based on snow melting effect

导电沥青混凝土结构设计过程中,电极的设计与优化是关键工作,决定着导电沥青路面的导电效率,影响路面融冰雪的效果。在前期试验研究的基础上,选择两种最具代表性的电极形式进行影响因素分析及优化方案设计,分别改变电极的间距、长度、材质进行实验,对比导电沥青试件的融雪效果。优化结果显示,选择铜作为电极材料,并综合考虑成本及后期对路面使用性能的影响,推荐最佳电极形式为单束铜电极,且间距为4 cm时沥青路面性价比及升温效果最佳。

The design and optimization of electrode is the key work in the design of conductive asphalt concrete structure.On the basis of preliminary experimental research,two most representative electrode forms were selected for influencing factor analysis and optimization scheme design.Then the distance,length and material of electrodes were changed respectively to compare the snowmelt effect of conductive asphalt specimens.The optimization results demonstrate that copper is selected as the electrode material,considering the cost and the influence of the later stage on the pavement performance,and single beam copper electrode is recommended as the best electrode form,with spacing of 4cm and the heating effect of asphalt pavement is the best.
