Abstract: Permeable pavements are a sustainable urban drainage system (SuDs) technique consistently employed as a stormwater management approach to mitigate against uncontrolled runoff that creates flooding in urban areas. Despite its effective implementation in managing stormwater runoffs, numerous researchers have recognized the need to improve the design approach of permeable pavement to ensure it is a truly sustainable stormwater management technique. Recent research studies have highlighted the possibility of substituting traditional natural materials (like rocks, gravel, and sand) used in constructing permeable pavement with recycled materials such as recycled aggregates. However, a research gap exists when considering the hydrological and pollutant removal performances of permeable pavements containing recycled materials. This research investigates a novel permeable pavement system's hydrological response. The laboratory also designed and adapted a rainfall simulator to simulate rainfall on the permeable pavement. The permeable pavement system rigs were measured as 0.1225 m2. The research focused on the hydrological performance test. The sustainable (recycled) materials included coconut coir, smoked Cameroon Calaba clay, and recycled carbon charcoal. The study revealed that the lag time of the pavement system designed with a recycled material increased between 123% - 225% compared to permeable pavement with traditional construction materials. The total volume retention capacity in the rigs with recycled materials ranged from 38% to 65%.
