Transferring Crumb Rubber Modified Gap Graded Asphalt Technology to Queensland

International experience have shown that crumb rubber modified gap graded asphalt can provide improved resistance to crack reflection compared to conventional asphalt mixes. In addition, the use of recycled end-of-life tyres has significant environmental and sustainability benefits. However, there are currently no specifications available for these mixes in Queensland which is a major barrier that prevents road agencies to make use of the benefits offered by this particular type of asphalt.

Implementation of Intelligent Compaction Technology for Use in Queensland

Compaction is one of the most important processes in roadway construction. Achieving adequate and uniform compaction of earthworks and pavement materials will ensure long-lasting performance of road infrastructure. This project aims to explore and facilitate the adoption of the Intelligent Compaction (IC) technology in Queensland for earthworks and pavement materials.
