Pervious concrete mixture optimization, physical, and mechanical properties and pavement design: A review

Pervious concrete has made a comeback as a green infrastructure solution for urban areas. The fast adoption of the permeable pavement practice by many cities worldwide warrants an urgent response from researchers to address the lack of standards for mixture optimization, pavement design, and characterization methods, which results in field placements with insufficient strength and durability. These critical issues are the topic of this review paper. Laboratory test results relevant to the mechanical and hydrological performance of pervious concrete, e.g., compressive and flexural strength, impact and abrasion resistance, porosity and permeability, and their interrelationships are discussed in great detail. The use of additives, alternative binders, fillers, and fibers from natural sources and waste streams and their impact on pervious concrete performance parameters is reviewed. Efforts in computational modeling of mechanical, structural, and hydrological behavior of pervious concrete materials and pervious concrete pavements are also presented. Based on this extensive review of state of the art on these important matters, the areas of need for future research are identified. (C) 2020 Elsevier Ltd. All rights reserved.
