Abstract

This study investigated the hydraulic and acoustic properties of high strength pervious concrete (HSPC) designed for urban pavement applications. The research focused on the use of recycled concrete aggregate (RCA) in two sizes, 4.75–9.5 mm and 9.5–12.5 mm, to enhance the mechanical strength and sustainability of HSPC. A novel mixing technique combining ultra high performance mortar (UHPM) with RCA was developed, incorporating high volume ground bottom ash (G-BA), fly ash (FA), and calcium stearate (CSt) as binder replacements. The evaluation included measurements of strength and density, void ratio, sound absorption (SA) coefficient, and spectral reflectance (SR), alongside assessment of clogging resistance under varying sediment concentrations. HSPC with higher CSt content demonstrated superior long-term clogging resistance, maintaining higher permeability over time. Exponential trendlines predicted a service life of up to 84 years under clogging conditions. Compressive strength of HSPC ranged from 30.8 to 41.8 MPa. A strong correlation was observed between total void and connected void content. Cross-sectional voids obtained through image processing further supported the pore structure analysis. While CSt had minimal effect on total void content, it significantly influenced compressive strength, density, clogging behavior, and spectral reflectance. Aggregate size also played a vital role in improving the functional durability of HSPC in clogging environments. These findings offer valuable guidance for optimizing pervious concrete mixtures with enhanced hydraulic and acoustic performance for long-lasting, eco-friendly urban pavements. © 2025 Elsevier Ltd.
