导电沥青混凝土融雪化冰热输出功率计算方法

Calculating Method for Heat Output Power Based on Removing Snow and Ice of Conductive Asphalt Concrete

通过分析导电沥青混凝土融雪化冰时的传热机理,采用传热学基础研究不同外部环境时热交换的具体计算方法,建立热输出功率与降雪量、气温、空气湿度、风速等参数的关系,为基于融雪化冰的导电沥青混凝土的材料和结构设计奠定基础。理论计算证实具有良好电学性能的沥青混凝土(体积电阻率为1—100Ω/m)可用于路面除雪化冰。

Based on thermal conduction mechanism of removing snow and ice of conductive asphalt concrete, heat transfer theory was employed to study relevant calculating methods under different external environmental conditions. The relationships between heat output power and the related parameters such as snowfall, air temperature, humidity, and wind speed were built up. This proposed approach is expected to provide a fundamental understanding for material and structural design of conductive asphalt concrete based on removing snow and ice. Theoretic calculation demonstrated asphalt concrete with excellent electrical property of volume resistivity 1--100Ω/m could be applied for removing snow and ice.
