TSA has funded 18 projects to a total of over $2 million through the Tyre Stewardship Research Fund. Some of the projects are still in negotiation or are yet to been announced. The current projects underway are listed below.
They operate in diverse project areas including explosives manufacturing, road, rail, building infrastructure and carbon composite material research.
There are a number of different organisations and partnerships funded including tyre recyclers, universities, road agencies, state government authorities.
The Fund is always open for applications.
Swinburne University & VicRoads
An applied research project undertaken with VicRoads and Sustainability Victoria to characterise and assess the engineering properties of tyre-derived aggregate as a supplementary material with recycled crushed concrete and crushed rock in pavement and roads subbase applications.
University of Wollongong & Ecoflex
This project examines the performance of a rubber- based energy absorbing layer (REAL) as a capping stratum (beneath the ballast) to minimise railway track degradation. This project assessed the utilisation of whole tyres with a sidewall cut off them and filled with aggregate as a means of absorbing vibration to enhance rail ballast performance and longevity.
University of NSW & Green Distillation Technologies
Developing Graphene Integrated Super-composite materials using end-of-life tyres. This project is looking at the utilisation of chemicals from the pyrolysis of tyres to create graphene composite materials for high value applications.
Australian Road Research Board (ARRB) Queensland, Transport and Main Roads Queensland, Department of Environment and Heritage Queensland
This project focused on the transfer of proven crumb rubber modified surfacing technologies to Queensland in order to optimise the use of recycled tyre rubber with an initial focus on increasing the use of spray seals in Queensland. It has also been an important project in monitoring emissions associated with the use of crumb rubber asphalt (CRA) – a key market barrier to the products greater utilisation in Australia. Finally, this project saw the creation of specifications for open graded asphalt in Queensland. The intent will now be to extend the use of this specification across Australia via AustRoads.
ARRB Victoria, VicRoads & Sustainability Victoria
This project focused on the development of an evidence based strategy to revise current VicRoads asphalt specifications to identify engineering and economically viable applications for CRA. Work to date has focused on crumb rubber in dense graded asphalt and the ‘structural fatigue layer’. This work complements that which is being undertaken in Queensland.
University of Melbourne & PreFab Australia
This project looks at the use of tyres as a low-density aggregate in lightweight concrete sandwich panels for construction. Results to date are promising and further work is looking to see how crumb rubber can replace foam concrete (which can falter structurally) which will increase potential load bearing while still maintaining low weight and insulation properties required.
University of Melbourne & Merlin Site Services
High speed polymer coating of rubber crumb fuelled explosives: This is an exciting project that looks at the development of a high-speed method for using rubber in on-site production of explosives at mines, quarries and construction projects. It is an innovative, world first application that has the potential to consume tyre-derived product in the tens of thousands of tonnes.
University Wollongong and the Rail Innovation Cooperative Research Centre
Performance of recycled rubber inclusions for improved stability of railway: Identify opportunities to use rubber mats manufactured using tyre rubber to improve rail ballast performance and replace more-costly, imported geo-synthetic materials.
Polymeric Powders & Austeng
Tyre crumb derived Polymeric Powder/Polyolefin composite material piping: This is another exciting project looking at the development and testing for a new injection moulded tyre rubber and plastics composite product. The project involves testing the new plastic/rubber composite material piping for oil & gas, irrigation and sewerage pipes. Further applications of the technology include 3D printing.
University of South Australia and the Australian Research Centre
To demonstrate that reinforced crumb rubber concrete is an economically viable and sustainable alternative to conventional reinforced concrete for residential structural engineering applications.
Assessment of liquid fuel, chemicals and porous material production from end-of-life tyres. This project involves an independent assessment of the tyre pyrolysis method to measure process outputs in an empirical and unbiased manner. Such information is integral to the discussions around these technologies as the Australian market matures.
Flexiroc & Talwood Park Racing
The project will provide a new benchmark for an engineered free-draining racetrack for the thoroughbred racing industry in Australia using tyre-derived aggregate in the track sub base. The successful project will open up the market in Australia to a totally new technology with all the advantages of increased track utilisation in all weather conditions, improved ride for both horse and rider and reduced deaths and injuries.
