Urbanization has resulted in the replacement of pervious vegetative lands with impervious surfaces such as pavement, which reduces the area where infiltration to groundwater can occur, thus increasing surface runoff into streams or accumulation of stormwater that can lead to flooding. To protect road pavement and travelers from water-related damage, stormwater must be drained from the roadway. Stormwater runoff from roads is known to contain contaminants. Transportation agencies in the country are required by the Environmental Protection Agency (U.S. EPA) to comply with the National Pollution Discharge Elimination Standard (NPDES). These include planning and design permit requirements for the treatment of stormwater runoff to ensure that rainwater runoff from roads (including local, state, and federal roads) do not carry pollutants into receiving water bodies such as rivers, creeks, lakes, and streams. To comply with the U.S. EPA requirements, transportation agencies must implement Stormwater Best Management Practices (BMPs) to capture and treat stormwater runoff from road surfaces.
One of the BMPs is the use of permeable pavement that allows stormwater to move through the pavement layers (away from the road surface) where it can either infiltrate into the soil and groundwater or drain to the road shoulder where it is collected for treatment as needed. There is limited evidence, however, regarding any traffic safety issues associated with highway stormwater and the type of permeable pavement suitable for various traffic requirements.
The primary objective of this project is to conduct a comprehensive literature review on (1) the effect of stormwater on defects of road surfaces (pavement), (2) traffic safety issues associated with highway stormwater, (3) the use of permeable pavement to manage highway stormwater, and (4) the identification of gaps in the existing literature for further research. .

Dr. Ndon received his bachelor’s and master’s degree in Mathematics from Harding University and Western Illinois University (Applied Mathematics) respectively prior to enrolling for his engineering degrees at Iowa State University. Dr. Ndon joined San José State University in 1996 as assistant professor and was promoted to associate professor and full professor in 2001 and 2007, respectively. He served as the Department chair for two terms (eight years at four years each term) from August 2008 to August 2016.
Dr. Ndon’s research focuses on water and wastewater treatment, stormwater management and treatment, environmental sustainability, and impact of stormwater on waterways and pavement durability.
Dr. Ndon has published several peer-reviewed journal and conference papers over the last twenty years. He has successfully performed several federal- and/or state-, county/district-, city- and industry-funded environmental projects.
AKTHEM AL-MANASEER, PhD
Akthem Al-Manaseer is the Charles W. Davidson Professor and former chair in the Civil and Environmental Engineering Department at San Jose State University. Dr. Al-Manaseer has been an educator for the last 33 years actively teaching classes on engineering materials and structures.
