This paper reviews the current status of permeable pavement research and limitations of its applicability. This discusses the influence of design factors such as permeable pavement type, mix design of porous concrete/asphalt, aggregate materials, particle size and distribution, sub-base depth, and layer setting on hydraulic, structural, and environmental performances of the pavement. Findings of this review demonstrate that the uptake of permeable pavement systems as a stormwater best management practice is relatively limited and slow due to lack of in-depth scientific understanding and economic uncertainties. It confirms the necessity of undertaking further research to fill the knowledge gap by providing practical solutions supported by new knowledge and innovations on permeable pavemen systerms. Followings have been identified as challengers and needs for future research on permeable pavement systems: (a) unavailability of cost data and difficulties of estimation of intangible benefits; (b) co-optimising environmental, hydraulic, and structural performances by modifying design; (c) difficulties of simulating actual field condition to investigate the clogging phenomena via laboratory experiments; (d) modelling the relationship of design variations with structural, hydraulic, and environmental performance; (e) developing a standard maintenance procedure to restore infiltration capacity; and (f) improving the bearing capacity of the structure to withstand higher vehicular loads and speeds.

In the future, permeable pavements including the full depth permeable pavement (FDPP) will be part of an integrated sustainable transportation program. When designed properly, FDPP can be used as an alternative best management practice (BMP) for stormwater runoff management. From a practical point of view, FDPP must maintain specific characteristics throughout the life of the pavements : (1) have adequate subgrade reservoir capacity to capture runoff volume, (2) surface pavement remain highly permeable and unclogged, (3) allowing minimum permeability of subgrade soil to infiltrate the captured runoff, and (4) assuring no adverse impact on underground water. During the past ten years the University of California Pavement Research Center (UCPRC) conducted numerous research studies to address some of the above critical questions related to the application of permeable pavement with respect to the highway stormwater runoff management. The focus of this paper is to discuss and summarize the major findings of these collective studies related to: (1) hydraulic performance evaluation of permeable pavement, (2) permeability measurement of porous asphalt and pervious concrete paved surfaces, (3) clogging evaluation of permeable pavement surfaces, and (4) water quality and pollution control issues.

Permeable pavements have been gaining popularity throughout North America. Permeable pavements typically consist of pervious concrete, porous asphalt or permeable interlocking concrete block paving units over an open grade base/subbase layer(s). Permeable pavements are designed to infiltrate stormwater, reduce peak flows, filter and clean contaminants in the water stream and promote groundwater recharge. They have become an integral part of low impact design and best management practices for stormwater management. In order to be effective, permeable pavements must be designed to provide sufficient structural capacity to accommodate the anticipated vehicle loadings as well as deal with stormwater flowing into and out of the permeable pavement. While there have been many well designed and constructed permeable pavements, this is a relatively new technology and there have been some "issues" with their performance. This paper describes some of the basics of best practices, design, construction and maintenance considerations for permeable pavement design and construction and focuses on best practices of permeable pavement design and construction in North America.

Accumulation of storm water on road surfaces and the associated runoff result in environmental pollution problems, negative impact on durability of pavement and safety problems for the travelling public. Permeable pavement has been used to reduce imperviousness of paved surfaces and storm water runoff due to the presence of pores through which water passes into underneath layer of the pavement where the water is collected for treatment prior to discharge into the environment. As a result, permeable pavement is seen as an environmentally sustainable system. Although permeable pavement was initially developed for foot and bicycle traffic, because of sustainability benefits it provides, there is growing interest in advancing the use of permeable pavement in highway storm water management. This article presents trends in the application of permeable pavement in highway storm water management and some associated highway safety benefits.

Permeable pavements typically consist of pervious concrete, porous asphalt, permeable interlocking concrete paving units or grid type systems over an open-graded base/subbase layer(s). Permeable pavements infiltrate stormwater, reduce peak flows, filter and clean contaminants and promote groundwater recharge. They have gained substantial popularity in North America and have become an integral part of low impact design and best management practices for stormwater management. In order to be effective, permeable pavement must be designed to provide sufficient structural capacity to accommodate the anticipated vehicle loadings, manage stormwater flowing into the surface and soil subgrade, as well water draining out of the base/subbase. While there are many well-designed and constructed permeable pavements, they are a relatively new technology with some projects performing below design expectations. This paper describes some essential best practices for permeable pavement design and construction, and focuses on lessons learned from case studies of permeable pavement construction in North America. Included are driveways, parking areas, roadways, roadways shoulders, walkways and unusual uses of permeable pavements subjected to heavy loadings including buses and even military tanks.
Pervious Pavements System (PPS) have been shown to possess a wide range of properties to effectively manage stormwater at source. The most popular PPS structure used in the UK and Spain consists of a permeable surface made of different materials such as interlocking concrete blocks, porous concrete, porous asphalt and reinforced grass, a base layer of aggregates, a sub-base layer of gravel, and an intermediate layer of geotextile between the base and the sub-base layer. This paper reports on an investigation of the properties of a novel structure called OASIS® which was designed at Coventry University as an enhancement of the commercially available geotextiles when incorporated in the PPS. The impact of OASIS® on the hydraulic behaviour of a PPS was analyzed through the study of infiltration rate, throughout the PPS and time required to reach the steady-state stage behaviour of the water within the PPS, under extreme rainfall intensities of 100 mm/hr, 200 mm/hr and 400 mm/hr, corres...
Permeable Pavement provides the structural support of conventional pavement, but allows stormwater to drain directly through the surface into the underlying stone base and soils, thereby reducing storm water runoff. There are permeable varieties of asphalt, concrete, and interlocking pavers. Permeable pavements are designed with an open graded stone sub-base that allows water to pass through to the native soil and/or provides temporary storage. Some of the benefits to using permeable pavements include: a reduction in the amount of storm pipes and inlet structures required; the ability to have more parking areas built to accessible slopes (due to flatter grades achievable with porous surfaces); improved growing conditions of plant material in landscape islands due to air and water available through porous surface; pedestrian safety due to improved winter and wet weather pavement conditions.

Permeable pavement (PP) systems provide opportunities to mitigate the impacts of urbanization on receiving water systems by providing at source treatment and management of stormwater. However, they do not receive mainstream use throughout much of Canada and the USA because of a lack of local guidance documents, demonstration projects and performance data. Studies have repeatedly shown that PPs attenuate stormwater flows by reducing volume and frequency of stormwater flows, reducing and delaying peak flow rates, and increasing flow durations. PP systems have been shown to improve stormwater quality by reducing stormwater temperature, pollutant concentrations and pollutant loadings of suspended solids, heavy metals, polyaromatic hydrocarbons, and some nutrients. This review is intended as a comprehensive summary of the current state of knowledge of the environmental performance of PP systems. Published research is synthesized to examine the hydrologic performance, impacts to water qua...

Uncontrolled stormwater runoff not only creates drainage problems and flash floods but also presents a considerable threat to water quality and the environment. These problems can, to a large extent, be reduced by a type of stormwater management approach employing permeable pavement systems (PPS) in urban, industrial and commercial areas, where frequent problems are caused by intense undrained stormwater. PPS could be an efficient solution for sustainable drainage systems, and control water security as well as renewable energy in certain cases. Considerable research has been conducted on the function of PPS and their improvement to ensure sustainable drainage systems and water quality. This paper presents a review of the use of permeable pavement for different purposes. The paper focuses on drainage systems and stormwater runoff quality from roads, driveways, rooftops and parking lots. PPS are very effective for stormwater management and water reuse. Moreover, geotextiles provide additional facilities to reduce the pollutants from infiltrate runoff into the ground, creating a suitable environment for the biodegradation process. Furthermore, recently, ground source heat pumps and PPS have been found to be an excellent combination for sustainable renewable energy. In addition, this study has identified several gaps in the present state of knowledge on PPS and indicates some research needs for future consideration. © 2013 Taylor & Francis. http://www.tandfonline.com/doi/abs/10.1080/09593330.2013.782573#.UrDsvSeA_5M

Due to urbanization, large portions of vegetated territory have been replaced by waterproof surfaces. The consequences are greater outflows, lower infiltration, and lower evapotranspiration. Pavement systems made with permeable surfaces allow the infiltration of water, ensuring reduction of runoff volume. In this paper, the methods of analysis of the hydrological and environmental performance of the pavement systems are reviewed in the context of urban drainage and regarding their durability. The purpose is to present an overview of the studies published during the last decade in the field. The Pubmed and Web Science Core Collection electronic databases were used to conduct the scientific literature survey. This generated 1238 papers, of which only 17 met the criteria and were included and discussed in this review. The evidence drawn from the knowledge on which the document is based provides useful critical interpretations of existing studies to progress the current understanding on...

Urban stormwater runoff is a transport medium for many contaminants from anthropogenic sources. There are many alternative management strategies available to treat these contaminants. One of the technologies suggested for this purpose is the use of permeable pavements to minimise the quantity of surface runoff generated by impervious surfaces within an urban catchment. Reported herein are the results of a monitoring program undertaken to assess the effectiveness of permeable road surface for managing the quantity and quality of stormwater runoff. It was found that the catchment, where the permeable road surface was installed, had the effective imperviousness reduced from 45% prior to reconstruction of the road surface to less than 5% after reconstruction of the road. Furthermore, it was found that the generation of surface runoff from the permeable road surface required a rainfall intensity in excess of 20 mm/h. Finally, the quality of the surface runoff was found to be at the lower levels of runoff from road surfaces.
