Recycled construction and demolition materials in permeable pavement systems: Geotechnical and hydraulic characteristics

Abstract

Permeable pavements are increasingly being used as urban stormwater management systems. Permeable pavement systems enable stormwater to infiltrate through the pavement surface and into the filter layer. Three common recycled construction and demolition (C&D) materials; crushed brick (CB), recycled concrete aggregate (RCA) and reclaimed asphalt pavement (RAP) were investigated in combination with nonwoven geotextile to assess their suitability as filter materials in permeable pavements. A series of laboratory tests was undertaken to assess the geotechnical and hydraulic characteristics of the C&D materials in permeable pavement applications. As a worst case scenario, stormwater mixtures were ..
