ABSTRACT
ABSTRACT: This study aims to evaluate economic and environmental benefits of porous pavement surface using Life-Cycle Cost Analysis (LCCA) and Life-Cycle Assessment (LCA). The research will focus on application of porous surface for sidewalk. The life-cycle inventory data were collected from literature search, online database, project records, and contractor survey. The comparison study was conducted between pervious paving systems with storm water treatment function and the conventional impermeable pavement with Best Management Practices (BMPs) in storm water management. Three pavement alternatives are considered in this study, including conventional concrete, porous asphalt, and porous concrete. The study results can help quantify the costs and benefits of using porous pavement surface at light traffic condition and select the sustainable pavement option at the same performance level.
