Permeable Pavements

Over the past few years cities and suburbs have become larger and densely populated, areas to be covered by vegetation has now been replaced by the Infrastructure, parking lots and walkways the absence of these natural surfaces has greatly disrupted the cycle of water the excessive use of impervious coverings has left cities with the challenge of managing increased run of volumes Bank erosion, Flooding and water clogging. Today these problems post consider of the risks to the sustainable development of cities and suburbs areas its a serious matter that require immediate attention and reliable solution. Permeable Pavements is a simple and lasting solution that imitates the original hydrological characteristic of soil its primary function allows runoff water pass through it directly into the ground being filtered by different layers of aggregate prior to returning it into the soil this helps reduce the volume of runoff rainwater that reduces the strain on the rainwater management system the reduced amount of volume helps to avoid overloads and flooding. It improves water quality and helps ground water recharge and also reduces the heat island effect and can be used where vegetation is not suitable. Permeable Pavements is a comprehensive resource for the proper design, construction and maintenance of permeable pavement systems that provide a transportation surface and a best management practice for storm water and urban runoff. A cornerstone for low impact development (LID) and sustainable site design, permeable pavements are considered a green infrastructure practice. They offer many environmental benefits, from reduced storm water runoff and improved water quality to better site design and enhanced safety of paved surfaces. Commonly used for walkways, driveways, patios, and low-volume roadways as well as recreational areas, parking lots, and plazas, permeable pavements are appropriate for many different land uses, particularly in highly urbanized locations. This volume synthesizes todays knowledge of the technology, drawing from academia, industry, and the engineering and science communities. It presents an overview of typical permeable pavement systems and reviews the design considerations. Detailed design, construction, use, and performance information is provided for porous asphalt, pervious concrete, permeable interlocking concrete pavement, and grid pavements. Fact sheets and checklists help to successfully incorporate permeable pavement systems into design projects. Additional chapters summarize emerging technologies, maintenance considerations, hydrologic design approaches, key components for specification writing, and key areas for additional research. Appendixes include a fact sheet clarifying information on common concerns, as well as data tables summarizing water quality treatment performance and costs. Permeable pavements is an essential reference for engineers, planners, landscape architects, municipalities, transportation agencies, regulatory agencies, and property owners planning to implement this best management practice for stormwater and urban runoff.
