透水沥青路面结构与材料技术要求

Permeable Asphalt Pavement Structure and Material Technical Requirements

传统的非透水路面易造成地下水位降低、水量分配不均衡、水质恶化、热岛效应等生态和环境问题。为了缓解这一系列问题,"海绵城市"的概念因此产生,即通过"渗、滞、蓄、净、用、排"等多种技术途径,实现城市良性水文循环,而这一概念的实现是采用透水路面。透水路面作为一种新型路面铺装技术,该研究对其路面结构和材料进行介绍,如能成功引用,将积极支撑起海绵城市的建设与发展,取得显著的环境和生态效益。

The conventional non-permeable pavement is liable to cause the ecological and environmental problems such as the reduction of underground water level,unbalance distribution of water flow,deterioration of water quality and effect of heat island.In order to alleviate a series of problems,the concept of"sponge city"comes in.This concept realizes the good hydrologic cycle of city through various technological approaches of penetration,lagging,storage,purification,application and drainage.And the realization of this concept is relied on the permeable pavement.The permeable pavement is a new pavement paving technique.This paper introduces the pavement structure and materials.The successful application will positively support the construction and development of sponge city,and will achieve the remarkable environmental and ecological benefits.
