摘要
沥青路面高温会带来车辙等病害,并增加城市热岛效应,这对路面的使用质量、使用寿命和人类的生活环境产生不利影响,所以急需开发行之有效的沥青路面降温技术,以减少车辙等病害和缓解城市热岛效应。现有的沥青路面降温技术分为被动降温技术和主动降温技术,而主动降温技术能够更为有效地降低沥青路面温度,且具有智能性、自发性等特点。主动降温技术对应的降温沥青路面主要有热反射路面、相变调温路面、热阻路面、透水路面、能量收集路面、高导热路面。针对上述沥青路面主动降温技术,总结了沥青路面主动降温技术的原理特点、应用方式、运用于沥青路面的实际降温及路用效果,以及降温技术的新方法、新思路,探讨了沥青路面主动降温技术的缺陷和局限性,并对未来沥青路面降温技术发展趋势进行展望。
High temperature asphalt pavement will bring rutting and other diseases and increase the urban heat island effect,which adversely affects the quality of pavement,service life and human living environment,therefore it is urgent to develop effective asphalt pavement cooling technology to reduce rutting and other diseases and alleviate the urban heat island effect.The existing asphalt pavement cooling technology is divided into passive cooling technology and active cooling technology,while active cooling technology can reduce asphalt pavement temperature more effectively and has the characteristics of intelligence and spontaneity.The cooling asphalt pavement corresponding to active cooling technology mainly includes heat reflection pavement,phase change temperature regulation pavement,thermal resistance pavement,permeable pavement,energy harvesting pavement,and high thermal conductivity pavement.Regarding the above-mentioned asphalt pavement active cooling technology,this paper summarizes the principle characteristics,application methods,actual cooling and road effects applied to asphalt pavement,as well as the new methods and ideas of asphalt pavement active cooling technology,discusses the defects and limitations of asphalt pavement active cooling technology,and provides an outlook on the development trend of asphalt pavement cooling technology in the future.
