Depending on the type of surface pavement, permeable pavement can be termed as porous asphalt, pervious concrete, or interlocking concrete pavers. Because of their ability to reduce runoff volume and improve water quality as well as urban heat island, the application of permeable pavement in urban areas have increased tremendously as an alternative low impact development (LID) design for stormwater best management practice (BMPs). Many researchers including the PI of this proposed project performed research investigations to evaluate the performance of permeable pavement with respect to hydraulic performance, maintenance and clogging issues. At present, the PI in collaboration with researchers from the University of Minnesota is performing a comprehensive annotated bibliography for the Minnesota Department of Transportation (MnDOT). The focus of this project is to take advantage of MnDOT literature review effort and use the content of the annotated literature to prepare a summary white paper to include: (1) the results of failed permeable projects with primary cause of failure, (2) the identification of the most successful mix design and construction layers configuration, (3) the water quality benefits associated with permeable pavement, (4) the knowledge and data gaps to be considered for future research investigation.
