摘要

为制备电热性能良好的导电沥青混凝土,以石墨烯-碳纤维作为导电相材料,对沥青混凝土的电热性能进行研究。分析了导电沥青混凝土融雪化冰的传热原理及融雪化冰过程中热量产生和传递的计算方法,对导电沥青混凝土的马歇尔试件进行了升温实验,根据成本及发热效率确定了石墨烯最优掺量为0.5%(wt,质量分数),碳纤维的掺量为集料质量的0.3%,在此掺量下对导电沥青混凝土试件进行了升温实验和融雪化冰实验。并对导电沥青混凝土进行了结构设计,并分析了其可行性。

Abstract

In order to prepare conductive asphalt concrete with good electrothermal performance,graphene-carbon fiber(rGO-CF) was used as the conductive phase material.The heat transfer principle of melting snow and ice of the concrete,and analyzed the calculation method of the heat generation and transfer during the snow melting and ice melting process.The Marshall test piece of the concrete was subjected to a temperature increase test,and the optimal rGO was determined according to the cost and the heating efficiency.The dosage was 0.5wt%,and the CF dosage was 0.3% of the aggregate mass.Under this dosage,the heating test and the snow-melting and ice-melting test were conducted on the concrete specimens.And the structure of the concrete was designed and analyzed its feasibility.
