Pervious Concrete Physical Characteristics and Effectiveness in Stormwater Pollution Reduction

Despite being promoted as a sustainable technology, the effectiveness of pervious concrete on pollution attenuation has not been fully investigated. The proposed study will investigate the contribution of pore/void structure characteristics of various pervious concrete mixes on water flow, its effectiveness on attenuating water pollution under clean and clogged conditions, and the impact of percolated polluted water on subsurface materials. Pervious concrete will be made with different cementitious materials and will be characterized for their physical properties such as pore distribution and sizes. Using a lab-scale system, the pervious concrete will be subjected to various rainfall conditions, clogging, and pollutant loadings to study the effectiveness of pervious concrete in pollution attenuation. The study will provide data on the performance of pervious concrete on mitigating surface runoff and pollutant attenuation and any correlation between the physical properties of the pervious concrete and water flow and the quality of the infiltrated water. This research addresses one of the U.S. Department of Transportation (USDOT) national goals of environmental sustainability.
