【摘要】 针对传统城市广场的非透水性铺装的生态性缺陷,探讨透水性沥青混合料在城市广场铺装中的设计及应用。基于减小地表径流、土基渗透能力及铺装溢流量等方面因素,设计透水性沥青混合料的目标孔隙率及铺装厚度;针对透水性沥青混合料铺装在使用中出现的问题,提出养护与管理措施。通过对透水性沥青混合料渗透性等方面的研究,为城市广场透水性铺装设计及其推广应用提供借鉴。更多还原

【Abstract】 The design and application of permeable asphalt mixture in the pavement of city square aiming at the ecological deficiencies of the traditional non-penetrating pavement. The target porosity and thickness of pavement of the permeable asphalt mixture on the basis of the factors such as reducing the runoff, the filter ability of soil base and pavement overflow. The maintenance and management measures are put forward aiming at the possible problems in the using of the permeable asphalt mixture pavement. The study of permeable asphalt mixture can provide reference for the design, popularization and application of the permeable pavement of city square.更多还原
