The City of Mitcham, in South Australia, is the latest local government authority to work with TSA on testing new mixes of crumbed rubber asphalt that can improve road durability and offer a significant recycling use for the millions of used tyres Australia generates each year.
Retaining walls have been around since the most ancient of civilisations and the engineering challenge of turning sloping sites into multiple flat levels has seen the same basic principles applied since those times.
With Australia generating more than 56 million end-of-life tyres per year, there is huge potential to turn an environmental challenge into an opportunity to improve Australia’s roads.
The casual observer could be forgiven for thinking that the only likely use of recycled tyre products in sporting venues could be in the synthetic athletic tracks. The reality is that all that appears to be just grass or sand, may well not be.
Geelong based joint high-tech manufacturing companies, Polymeric Powders and Austeng, are using end-of-life tyre crumb combined with polyolefin plastic to manufacture a superior quality composite material, enabling the production of commercial pipes using an Australian developed ‘world’s first’ process.
The commercialisation of innovative technologies could, in the near future, see trucks running on tyres that will subsequently find a second life not only in the road surface but also in the fuel powering the rig.
