The crumb rubber asphalt demonstration trial was a collaborative effort organised by Tyre Stewardship Australia (TSA), Department of Transport (DoT) Victoria, and the Australian Road Research Board (ARRB). The project was undertaken with the cooperation of local asphalt manufacturers at East Boundary Road, East Bentleigh, Victoria.

The initial results showed an improvement in condition for all measures with the new surface in place, and the ongoing monitoring has observed good performance over the two-year monitoring period of the trial.

A study of the environmental emissions during the asphalt paving was undertaken to measure the potential fuming exposure of crumb rubber asphalts, and to provide a comparison to control mixes. The analysis found no significant fuming exposure to volatile organic compounds. Detected values of total suspended solids, bitumen fumes, and polycyclic aromatic hydrocarbons were below recommended guidelines, and were lower for the crumb rubber asphalts compared to the control asphalts.
