ABSTRACT

The stormwater runoff and infiltration performance of permeable pavements has been systematically evaluated within an intensive monitoring program. The primary objective of the investigation was to generate a broad database, which enables the development of an advanced simulation module for urban drainage modelling. Over 160 field and lab scale experiments have been completed and analyzed for surface runoff and infiltration characteristics. The test series include several pavement types under various boundary conditions such as diverse precipitation impacts, varying surface slope and layer construction as well as different stages of surface clogging and several base and subgrade layer characteristics. The results represent a reliable and comprehensive database that allows profound conclusions and substantial recommendations.

    • "The surface runoff contained TSS in the Young (2008) research was applied continuously and from top of the pavement [7]. Illgen et al. (2007) conducted a study on permeable pavement clogging phenomenon. The TSS used in this survey were silica stones [8]. "

    ABSTRACT: Urbanization expansion increases impermeable surfaces and ultimately produces more runoff from urban surfaces. The runoff in the urban streets moves the pollution with high levels from the city and then collects into channels where they are transported into the water courses. The most important factor in runoff polluting is sediments. If the sediments are removed from runoff, their quality will be improved. One of the effective systems to reduce sediments from the surface runoff is permeable pavement. In this study, a simulator system is used. The sample of permeable pavement analyzed consisted of two layers of geotextile bedding, filter granular layer (2.36 to 4.75mm), sub-base granular layer (4.75 to 20 mm) and concrete blocks. The area and slope is 2m2 and 2%, respectively. This study evaluates the life efficiency of permeable pavement subject to sediment loading and also evaluates it in removing pollution from the artificial surface runoff. Over a simulated 7 years of sediment loading conducted in the laboratory, the results showed 100% sediment retention, with runoff coefficient 0.35 at the end of the seventh year of simulations. An analysis indicated that the ammonia-nitrogen removal efficiencies were 56%.

    • "Clogging, the loss of surface permeability, in PP systems has been documented by numerous researchers in both field (Bean et al., 2007; Henderson and Tighe, 2011) and laboratory based studies (Illgen et al., 2007; Pezzaniti et al., 2009; Haselbach, 2010; Tan et al., 2003). Clogging materials are deposited onto the surface of a PP from vehicular traffic, vegetative litter, atmospheric deposition and regular maintenance activities. "

    • "There have been numerous laboratory-based studies on the infiltration performance of permeable pavements on slopes up to 5% (Davies, et al., 2002; González-Angullo et al., 2008) and even up to 10% (Shackel et al., 1996; Illgen et al., 2007; Castro et al., 2007). However, as these studies were all laboratory-based, the application of the study results to the design of operational permeable pavement systems is questionable. "

    ABSTRACT: This paper describes the infiltration performance of a new 18 m 2 PICP test pavement under a variety of different flow conditions and pavement slopes. The initial results show that there is a clear relationship between pavement slope and the infiltration capacity through the pavement surface. Generally this relationship has demonstrated that the infiltration capacity at the surface of PICP systems will reduce as the slope of the system increases. However, the results also showed that the PICP test pavement used in this study had high infiltration rates of , even at slopes up to 20%. This suggests that typical PICP design guideline recommendations of maximum pavement slopes of 5% are probably overly conservative. The results of this investigation also showed that a significant amount of lateral movement of water occurred within the pavement structure and this was thought to be mainly caused by a geofabric layer that was included between the bedding and basecourse layers.
