Porous Concrete Pavements (PCPs) are increasingly recognized for their potential to address environmental challenges, particularly in urban settings, by mitigating water and air impacts and enhancing road safety. Despite their promising attributes, their widespread adoption remains limited due to gaps in comprehensive research and awareness about their multifaceted benefits. This review paper delves into the essential properties of PC mixtures to underscore their role in designing sustainable and multifunctional pavements. Drawing from recent literature, the paper synthesizes the environmental advantages of PCPs, encompassing benefits such as reduced stormwater runoff, enhanced underground water quality, mitigation of the heat-island effect, noise reduction, and improved skid resistance. The hydraulic efficacy of PCPs hinges on various factors including mix design, construction practices, and environmental conditions, making simultaneous optimization of mechanical attributes, durability, and infiltration challenging. Persistent issues like freeze/thaw damage, deicer impacts, and clogging hinder their broader application. Durability concerns, especially in colder climates, underscore the need for advancements across the PCP lifecycle stages. The review emphasizes the need for improved characterization techniques and predictive modeling to propel PCP technology forward. Additionally, the paper highlights emerging research areas, including nano-science and nano-engineering, as potential avenues to address durability challenges and amplify the environmental benefits of PCPs.
