Investigating the use of recycled plastic in future sustainable road infrastructure

Project Overview

Current waste management challenges across the world have required governments to develop innovative policies that target the recycling and reclamation of single-use materials back into the economy. Sustainable materials and construction practices are the future of road infrastructure in Western Australia and present a potential means to productively find a new life for single-use materials. Currently, a number of organisations have begun researching and implementing recycled waste plastics in asphalt. While the proprietary nature of these products limit data availability, supplier claims indicate the materials do not have a detrimental effect on laboratory performance. Further, there is still a requirement to develop harmonised specifications and assessment methodologies. WARRIP in collaboration with the National Asset Centre of Excellence (NACOE) in Queensland, are dedicated to gaining a full understanding of how best to use recycled and reclaimed plastics in road infrastructure without adversely affecting workplace health and safety or environmental outcomes.
