On Porous Materials From The Landscape Pavement Design

Nowadays, cities are facing deteriorating ecological and living environment as well as water shortage problems. Besides giving us a basic landscape function, porous pavement provides us with a ecological and economic solutions to those issues. Impermeable pavements lead to substantial flooding. This creates danger to drivers due to the wet condition. Whenever there is heavy downpour, rain water can only be diverted to rivers through the underground drainage system .This, not only increases the burden of the existing drainage system, but also wash down surface pollutants down the drainage system. Without a permeable or semi-permeable road surface, there are only 2 types of road conditions: being flooded in wet weather or drought on a sunny day. If we want to increase the air/water permeable surfaces in a city, we have to use porous materials to construct roads, pavements etc. This can effectively reduce the negative impact of impermeable ground surfaces to the cities. In this way, we can balance economy growth with environmental growth. Porous pavement has become one of the important landscape elements in our urban transformation and building.This thesis attempts to explain in detail the feasibility of using permeable materials in conjunction to a number of case studies worldwide. Hopefully, the result can form the basis of the feasibility of porous materials usage in our country.
