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.

    • "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.

    • "Compared to clogging effects, the surface slope has only a minor impact on the infiltration capacity (c.f. Illgen et al., 2007). Depending on the type of pavement and the particular grade of clogging, the rain intensity may be more crucial as well. "

    ABSTRACT: The stormwater runoff and infiltration performance of pavement structures has been systematically evaluated within an extensive research project. Over 230 field and lab scale experiments have been completed and analyzed for surface runoff and infiltration characteristics as well as for water content changes inside the construction. The test series comprises several types of conventional and explicitly permeable structures under various boundary conditions. In addition, the field data have been superimposed on the results of former infiltration tests accomplished by several researchers to a unique database containing over 350 single infiltration tests and enabling substantive statistical analyses. Based on these widespread monitoring results, the primary characteristics of the specific infiltration phenomenon on pavements have been determined. The analyses yield to an identification of the governing constraints, to a quantification of their impacts on the infiltration capacity of the entire pavement construction and finally to the development of an advanced conceptual approach for modelling runoff and infiltration processes on pavement structures. Moreover, profound recommendations for type specific infiltration rates, runoff coefficients and parameter values for conventional applications have been worked out, which facilitate planners a better estimation of the stormwater runoff contributed by the manifold types of more or less permeable pavements.
