现代城市的地表逐步被建筑物和硬化路面覆盖,由于这些硬化路面缺乏透水性和透气性,雨水不能渗入地下,很难与空气进行热量、水分的交换,缺乏对城市地表温度、湿度的调节能力,产生所谓的“热岛现象”。给城市的生态环境带来诸多负面影响。因此采用既能涵养地下水又能改善生态系统的透水性路面,增加城市的透水,透气空间,改善城市的生态环境,已引起社会各方的重视。 透水路面在欧洲、日本、台湾早有采用,分成两个方向,其一是:仅面层
The surface of modern cities is gradually covered by buildings and hardened pavements. Due to the lack of water permeability and permeability of these hardened pavements, rainwater can not penetrate into the ground and it is difficult to exchange heat and air with the air and lack the ability to adjust the surface temperature and humidity of cities , Resulting in the so-called “heat island phenomenon.” To the city’s ecological environment has brought many negative effects. Therefore, adopting the permeable pavement which can conserve groundwater and improve the ecological system, increasing the pervious and breathable space of the city and improving the urban ecological environment have drawn the attention of all sectors of society. Permeable pavement in Europe, Japan, Taiwan has long been used, divided into two directions, one is: only the surface layer
