摘　　要：北京市延庆区松闫路作为2022年冬奥会保障道路,举办期间正值寒冬,要求能够快速,高效地清除冰雪,保证道路交通畅通。因此,在大修中需要在沥青表面层掺加道路用相变材料,从本质上改变沥青路面性能。道路用相变材料利用存储的太阳能和机械能,在低温时释放相变潜热,使道路表面温度升高,主动融化冰雪。因此阐述了相变材料的作用机理和在道路工程建设中的应用意义,并进行了经济、社会和环境效益的分析。Songyan road in Yanqing,which is guarantee for the 2022 Winter Olympic,is required to clear ice and snow quickly and efficiently to ensure the traffic smooth.During the process,road phase change material was added to the asphalt surface so that the asphalt property was changed essentially.By utilizing the stored solar energy and mechanical energy,the latent heat was released at low temperature,the temperature of road surface was increased to melt ice and snow actively.The mechanism of the phase change material and its application significance in road construction are expounded and its economic,society and environmental benefits are analyzed.

关 键 词：冬奥保障道路 道路用相变材料 主动融冰雪路面 安全 环保.
