Case study: Crumb Rubber Modified Bitumen


Used tyres are recycled and processed into crumb rubber, which is blended into bitumen to be used in asphalt and sprayed seals.

Crumb rubber not only recycles old tyres, but can improve the longevity and performance of roads.

By June 2021, the Department of Transport and Main Roads (TMR) is forecasting to use approximately 1.1 million tyres in sprayed seals and asphalt.
