Downer and Adelaide deliver Australia’s first recycled road

In an Australian-first, the City of Adelaide has partnered with Downer to construct Australia’s first road made completely from recycled material.

The recycled road is made up of reclaimed asphalt pavement from local streets and recycled vegetable oil.

The asphalt mix was processed through Downer’s asphalt plant in Wingfield, before being laid on Chatham Street in the city’s south west.

Downer’s General Manager Pavements, Stuart Billing, said the event demonstrates the importance of partnerships.

“Together with City of Adelaide, we have set a new benchmark in achieving sustainable solutions, The 100 percent recycled road saves up to 65 percent CO2e emissions when mixed at a lower temperature (warm mix asphalt), compared to standard asphalt made with virgin materials,” he said.

“Our Australian-first 100 percent recycled asphalt is about 25 percent stronger than standard asphalt, which means it will be able to better resist deformation.”

Lord Mayor Sandy Verschoor said the demonstration aligns with the councils ambition to becoming a leading green, liveable and creative city.

“The project originates from a Motion on Notice brought to Council last year, which asked the administration to seek to maximise the amount of recycled material used within our roads,” she said.

“At around the same cost as the standard process, the recycled road is cost-effective and, as we’re recycling our own materials, it has a great benefit to the environment.”
