通过导电沥青混凝土路面施工工艺的研究,得出了导电沥青混凝土材料制备及施工过程中的技术措施。研究主要结论有:(1)研究提出了导电沥青混凝土材料制备技术。在普通沥青混凝土中加入导电材料,使得原本不导电的沥青混凝土层变成了导电的沥青混凝层,从而实现导电加热融冰化雪的目的。(2)分析提出了导电沥青混凝土均匀导电控制措施。在充分搅拌的基础上,确定合适的电极网尺寸和电极模块的分布尺寸,使得导电沥青混凝土并联工作并实现均匀加热,同时方便后期的维护和更换。(3)研究提出了导电沥青混凝土铺装技术。在实际铺装导电沥青混凝土时,应考虑摊铺和碾压机械对电极网和导电线的影响,确定了电极网的固定方式和导电线的合理位置。(4)研究提出了导电沥青混凝土的绝缘措施。分析了普通沥青混凝土、乳化沥青及环氧树脂粘结剂作为绝缘材料的可能性,指出普通沥青混凝土本身就是良好的绝缘材料,采用普通沥青混凝土作为绝缘材料即方便又经济。
Through the research of construction process of conductive asphalt concrete pavement, the technical measures of preparation and construction of conductive asphalt concrete material are obtained. The main conclusions of the research are as follows: (1) The preparation technology of conductive asphalt concrete is proposed. Addition of conductive materials into ordinary asphalt concrete makes the original non-conductive asphalt concrete layer become a conductive asphalt concrete layer, so as to achieve the purpose of conducting electric melting and snow melting. (2) Analyze and put forward the conductive control measures of conductive asphalt concrete uniform. On the basis of full mixing, determine the appropriate size of the electrode network and electrode module size distribution, making the conductive asphalt concrete work in parallel and achieve uniform heating, while facilitating the maintenance and replacement. (3) Research and put forward conductive asphalt concrete paving technology. In the actual laying of conductive asphalt concrete, paving and rolling machinery should be considered on the impact of the electrode network and conductive lines to determine the fixed manner of the electrode network and the conductive wire reasonable position. (4) The research proposes the insulation measures of conductive asphalt concrete. The possibility of ordinary asphalt concrete, emulsified asphalt and epoxy resin binder as insulation materials is analyzed. It is pointed out that common asphalt concrete is a good insulation material in itself, and it is convenient and economical to use ordinary asphalt concrete as an insulating material.
