The increasing use of pervious concrete as sustainable and environment-friendly paving materials is primarily owed to its ability to reduce pavement runoff. The mechanical and transport properties of pervious concrete with 50% ground-granulated blast furnace slag (GGBS) replacement were examined. Open-graded 10 and 20 mm aggregates were used to attain porosity of 10%, 15%, and 20%. Polypropylene short-cut fibres were added to the mix. The clogging potential of pervious concrete exposed to dust was investigated. The results indicated that increasing the porosity led to a decrease in compressive and tensile strength. The fibre addition was effective in low-porosity concrete. Permeability was proportional to porosity and inversely proportional to aggregate size. After 40-year simulated dust exposure, the concrete permeability could be restored with the water flushing maintenance process. In comparison to Ordinary Portland cement concrete, pervious concrete incorporating GGBS is a more sustainable paving solution, offering a decrease in cost, heat island effect, and embodied energy, while also reducing carbon emissions by 54%.
