摘要
为了进一步推动沥青路面降温技术的发展与应用,系统地调查了国内外相关研究动态,明晰了沥青路面光热环境,梳理总结了现有沥青路面降温方式及其降温原理,综述了各降温技术研究现状,并结合降温效果、路用性能、环境效应等对各降温技术进行了评价.评价结果表明:沥青路面降温技术包括主动降温与被动降温2种类型,其中主动降温技术基于降温原理可分为热阻集料降温法、热反射涂层降温法、辐射粉体降温法和相变材料降温法,被动降温技术可分为人工洒水法、路面储水降温法和热管降温法.4种主动降温技术均可达到良好的降温效果,且采用复合式结构或材料,如热反射-热辐射-隔热层复合降温涂层等还可进一步提升降温效果.
Abstract
In order to further promote the development and application of asphalt pavement cooling technology,the relevant research trends were systematically investigated at home and abroad.The photothermal environment of as-phalt pavement was clarified.The existing asphalt pavement cooling technology and principles were sorted out and summarized.The research status of each cooling technology was reviewed.Each cooling technology was evaluated based on cooling effect,road performance and environmental effect.The evaluation results show that asphalt pave-ment cooling technology includes two types of active cooling and passive cooling.Among them,active cooling tech-nology can be divided into thermal resistance aggregate cooling method,thermal reflection coating cooling method,radiation powder cooling method,and phase change material cooling method based on the cooling principle.And passive cooling technology can be divided into artificial watering method,pavement water storage cooling method,and heat pipe cooling method.All four active cooling technology can achieve significant cooling effects.The use of composite structures or materials,such as the composite cooling coating of heat reflection-heat radiation-heat insu-lation layer,can further improve the cooling effect.
