摘要
分析导电沥青混凝土融雪化冰原理,利用导电沥青混凝土传导热量能力强且具有良好粘结性能的特点,将多相耦合作用下的导电沥青混凝土嵌入槽形普通混凝土中,形成一种新型桥面结构。通过实验研究,与单层导电沥青混凝土桥面对比,其热效率大幅提高,而散热损失显著降低,能即时融雪化冰,保证行车安全畅通,为桥梁冰冻灾害防治提供借鉴。
The analysis of conductive asphalt concrete melting snow and ice principle is based on the feature for excellent conduction heat capacity and adhesive property to embed conductive asphalt concrete of multiphase coupling effect into ordianry concrete then forming a new bridge deck structure.The experiment result shows that the heat-kept effect of conductive asphalt concrete bridge deck greatly increases while significantly reduces in heat loss,which can be used to melt snow and ice to guratee the driving safety and stability and provide reference to bridge freezing disaster preventation.
