Evaluation of Surface and Subsurface Processes in Permeable Pavement Infiltration Trenches

Abstract

The hydrologic performance of permeable pavement systems can be affected by clogging at the pavement surface and/or clogging at the interface where the subsurface storage layer meets the underlying soil. The objective of this paper was to evaluate changes in infiltration and exfiltration using three pressure transducers installed in piezometers along the length of two, 2.47-m wide, permeable pavement strips. Each system was retrofitted in the parking lane of a curb-and-gutter system in Louisville, Kentucky. The strips received run-on from a drainage area about
