Title: Case studies of recycled materials in pavements and footpaths
Biography: Arul Arulrajah
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 keynote presentation, applications of Construction and Demolition (C&D) materials in roads and footpaths based on research currently undertaken in Australia are discussed. Unbound and stabilized C&D materials have been evaluated by the presenter to assess their viability for reuse in pavement bases/subbases. C&D materials including Recycled Concrete Aggregate (RCA), Crushed Brick (CB), Reclaimed Asphalt Pavement (RAP), Fine Recycled Glass (FRG) and Waste Rock (WR) have been evaluated in the laboratory and new specifications successfully developed in Australia to incorporate their usage in pavements, footpaths and other civil engineering applications. In addition, several unique field case studies where C&D materials have been used in roads and footpaths in Australia will also be presented. In addition current ongoing projects on some other traditional waste materials currently being researched by the presenter will be briefly discussed.
