Development of a sustainable high friction surface treatment containing post-consumer recycled glass

High friction surfaces using calcined bauxite are a crash reducing and lifesaving technology for high-risk locations on roads, such as small radius curves, steep descents, urban and rural intersections, and approaches to pedestrian crossings. Austroads has adopted a crash reduction factor of 40%, and 50% for wet weather crashes. However, international studies have found much higher reductions when used in a targeted way, including a recent statistical study for the US Federal Highways Administration finding a reduction of 57% in total crashes on curves and 79% reduction in total crashes on ramps. This paper introduces high friction surfaces. It then explains how OmniGrip Direct and the Australian Road Research Board (ARRB) - now National Transport Research Organisation (NTRO) - collaborated in the development of a new more sustainable high friction surface treatment by blending post-consumer recycled glass with a high friction aggregate. The blend enables local and State governments to divert their waste glass from landfill or being used as a sand substitute, to saving lives, reducing injury and reducing risk on their roads, in their community. The development of the new surfacing and an Environmental Product Declaration have been part-funded by grants from Sustainability Victoria and support from ecologiQ, a Victorian Government initiative to optimise the use of local recycled and reused materials in government infrastructure projects, reduce waste and contribute to a Victorian circular economy.
