Globally 1.5 Billion and in Australia 56 million tyres reach their end of life with less than 5% recycled. This project aims to create new knowledge and predictive models for the behaviour of bonded soft tyre and rigid rock aggregates through a multi-scale approach from particle scale investigation to large-scale observation and modelling. This will create new knowledge into the behaviour of this unconventional three-phase granular mixes; soft, rigid aggregates bonded with polymer binders. The project will provide significant benefits in diverting millions of tyres from landfills and illegal dumps and a more competitive and environmentally sensitive infrastructure industry.

全球有15亿条轮胎，澳大利亚有5600万条轮胎达到使用寿命，回收率不到5%。该项目旨在通过从颗粒尺度调查到大尺度观察和建模的多尺度方法，为粘结软轮胎和刚性岩石骨料的行为创造新的知识和预测模型。 这将为这种非传统的三相颗粒混合物的行为创造新的知识;软，刚性骨料与聚合物粘合剂粘合。该项目将带来巨大的好处，使数百万轮胎从垃圾填埋场和非法倾倒场转移出来，并使基础设施行业更具竞争力和环境敏感性。
