Abstract:
Flash flooding poses a significant threat, necessitating stringent stormwater management strategies. Pervious concrete pavements have gained traction as a sustainable solution to mitigate runoff, promote water infiltration, and mitigate flash flood risks. This paper comprehensively synthesizes various research endeavours to provide an in-depth understanding of pervious concrete pavements. The increasing adoption of permeable pavements reflects a global shift towards eco-conscious practices. However, the escalating use of pervious concrete underscores the imperative to address concerns regarding its strength and durability. This study meticulously examines crucial aspects such as mix designs, testing protocols, material characterization, and applications. It explores innovative approaches, including the utilization of additives and waste materials, to enhance sustainability and performance while minimizing the environmental footprint of conventional concrete production. By scrutinizing scientific databases, focusing on terms like pervious concrete and permeable pavement, the research underscores the significance of aggregate qualities, cement paste thickness, and other components in influencing mechanical and hydrological properties. Site-specific factors such as subgrade soil conditions and precipitation patterns significantly impact pavement performance. Challenges like inadequate strength, cracking, and ravelling are being tackled by integrating fibres and nano additives. The conclusion underscores the critical role of optimizing various components in pervious concrete for effective stormwater management. Data-driven recommendations for mix design, site-specific considerations, and additive usage are provided to practitioners. Despite advancements, unresolved issues persist in stormwater management through pervious concrete. Key findings highlight the need for continued research to address concerns related to strength, durability, and optimal performance under varying environmental conditions. By addressing these challenges, pervious concrete can further its role in environmentally sustainable stormwater management systems.
