City of Mitcham installs recycled tyre pavement

Paving material made with recycled tyres has been installed by the City of Mitcham, as part of a field trial in sustainable urban drainage design.

The permeable paving, created by the University of Melbourne with funding from Tyre Stewardship Australia, has been laid at St Marys Park in Adelaide.

The material is made from 50 per cent used tyres and is designed to assist water drainage through surface resistance.

Tyre Stewardship Australia CEO Lina Goodman said the City of Mitcham is one of many councils interested in investigating the performance of waste tyre permeable pavement.

“This trial will utilise four tonnes of tyre-derived aggregates, the equivalent to diverting 500 passenger tyres from the waste stream,” Ms Goodman said.

“This project is envisaged to be the first of many, and has been undertaken to demonstrate the effectiveness of the product.”

Ms Goodman said wide spread implementation of the material could see 300,000 tyres used in local government infrastructure per year.

“The use of end-of-life tyres as an aggregate blend for permeable pavement has various applications such as pedestrian walks, bike paths, car parks and low volume roads,” Ms Goodman said.

“TSA is eager to see more trials take place to showcase the products full potential in the urban environment.”

City of Mitcham Mayor Heather Holmes-Ross said the trial is a first for Australia, and will involve testing the permeable pavement under various traffic loads.

“We are very excited to be involved in this innovative trial. This paving product provides many benefits to the environment, including harvesting water to help water nearby trees and gardens,” Dr Holmes-Ross said.

“Not only does it sustain urban vegetation, it can help to increase groundwater recharge, reduce surface runoff, decrease the risk of flash-flooding and help with the treatment of storm water.”

Dr Holmes-Ross said equipment had been installed below the surface of the parking bays to monitor the performance of the pavement, as well as record the surface temperature of the different pavement colours.

“The pavement design has obvious benefits for water sustainable urban design, which will be evaluated during the trial,” Dr Holmes-Ross said.

The trial will also monitor the quality of water passing through the pavement structure, and evaluate its efficiency in reducing contamination of resulting waterways.
