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.
