摘要
作者利用室内试槽铺筑的沥青路面结构进行了热反射涂层路面结构的温度场试验与检测,并结合获得的试验数据,对比分析了路表设与不设热反射涂层两种方案的路表温度、变温速率、温度梯度、变温幅度和相位随深度的变化规律。最后,建立了有限元模型,和应用数值分析方法反算了主要热辐射特性参数。研究成果在保护西部地区冻土上限值和解决城市热岛效应等问题上有重要参考价值和良好的应用前景。
By using the asphalt pavement structure that was built in indoor laboratory tank, a temperature field test and the detection of heat-reflective coating of a pavement structure were carried out. Combined with the obtained experiment data, the variation laws of road surface temperature, variable-temperature rate, temperature gradient, variable temperature amplitude and phases with depth for setting and not setting heat-reflective coatings were
