The objective of this review paper was to discuss in detail the various sustainability benefits offered by pervious concrete (PC), while also documenting the current state-of-the-art pertaining to mechanical and hydrological characteristics. The prevailing mix design procedures as well as the impacts of additives and recycled materials on behavior of PC have been discussed. Impact of pore morphology on permeability was examined, and a note was made on current rehabilitation techniques for restoring the infiltration rate of clogged PC surface courses. Field studies that focused on design, construction, and performance monitoring of pervious concrete pavements (PCP), were highlighted. Additionally, the contribution of PCP to reduce the environmental impacts of built infrastructure was summarized. The multiple benefits offered by PCP such as runoff mitigation, heat alleviation, energy conservation, and emissions reduction make it a promising material for construction of environment-friendly PC roadways. However, there still exists a vast scope to enhance the material's characteristics for development of sustainable pavement systems in the urban built environment. (C) 2020 Elsevier Ltd.
