Sustainable Usage of Construction and Demolition Materials in Roads and Footpaths

Abstract

The increase in generation of waste from construction activities along with significant increase in global population has led to increasing focus and research on reuse of waste material. In this paper, the application of construction and demolition (C&D) materials in road works is reviewed and discussed. C&D materials were evaluated by laboratory testing methods to assess their viability for reuse in roads and footpaths. Several unique field case studies where C&D materials have been used are also reported. C&D materials studied include recycled concrete aggregate (RCA), crushed brick (CB), reclaimed asphalt pavement (RAP), fine recycled glass (FRG), and waste rock (WR). C&D materials were f..
