This paper reports on the recent developments of an investigation aimed at finding the value-added applications for reprocessed concrete waste. Present uses include road base material and drainage layers. In a further development the Infrastructure Services Management Research Group (ISM) for Swinburne University of Technology is currently assessing the mechanical and acoustic properties of concrete made from Recycled Concrete (RC) Aggregate. Some unique properties including porosity of RC Aggregate have been utilised in new Recycled Aggregate (RA) Concrete in the construction of pre-cast concrete sound panels. Sound absorbing characteristics and the robustness of RA Concrete panels make them suitable for acoustic barriers for urban freeways.
