Permeable pavement systems with low carbon and recycled materials for Caribbean Small Island Developing States

Abstract

This PhD research project targets the utilisation of permeable pavement systems (PPS) as a long-term, sustainable urban drainage option for flood risk mitigation and improvement in stormwater runoff quality in Small Island Developing States (SIDS) across the Caribbean. Additionally, the research assesses the performance of PPS comprising of recycled and/or waste materials in the sub-base layer. These innovative pavements are being considered to reduce the overall carbon footprint on the construction phase of pavements and to reduce the volume of natural material used in the construction industry. The recycled materials considered are Crushed Concrete Aggregates (CCA), Carbon-Negative Aggregates (CNA) and expanded polystyrene (EPS) beads. The research methods explored combine experimental and modelling through a quantitative research design approach
