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.
