Boral rolls out crumbed rubber asphalt across Sydney

Boral has partnered with eight Sydney councils for one of the largest crumbed rubber asphalt demonstration projects in Australia.

Boral provided 2000 tonnes of sustainable pavement material in addition to 1200 tonnes of controlled asphalt mix to be paved across local council streets.

Comprising recycled rubber from end-of-life car and truck tyres, crumbed rubber asphalt aims to improve the sustainability and longevity of council roads.

The Reusing Rubber: Recycling Tyres for Roads demonstration project by Southern Sydney Regional Organisation of Councils (SSROC) aims to make council roads more sustainable, reduce capital and operating expenditure by extending road life, and create a local market for old car and truck tyres by incorporating crumb rubber in bitumen.

An initial 3600 standard passenger car tyres or 2400 car and 490 truck tyres combined will be used in the crumbed rubber asphalt trial project.

Following Boral’s successful tender, it is partnering with eight of the 12 involved local councils in Sydney to pave a street in each area to explore varying levels of crumb rubber in a range of asphalt mixes.

These include Bayside Council, Burwood Council, City of Sydney Council, Woollahra Council, Randwick City Council, Sutherland Shire Council, Northern Beaches Council, and Inner-west City Council.

Tim Richards, executive general manager, asphalt at Boral, said the company is pleased to be working with local governments as they innovate and move towards a circular economy to drive sustainability.

“This is a huge-scale project that will drive benefits for the broader industry and governments of all levels as we look to better understand how recycled rubber asphalt can be tweaked for maximum performance,” Richards said.

“At Boral, we are committed to decarbonisation, and as part of this, we leverage our facilities to process recyclable materials such as construction waste, otherwise destined for landfill. It’s promising to see councils drive initiatives that demonstrate the benefits of repurposing waste, such as creating new roads through recycled tyres.

“We are eager to find ways to maximise benefits to the community and on road projects through innovative construction materials and methods. We look forward to partnering with more local governments on projects such as these.”

Over an initial 12-month period, the performance of each asphalt mix will be monitored in a range of applications and conditions to measure product benefits. The project will generate comprehensive data on the use of recycled rubber-based treatments on local roads and is expected to contribute to the development of crumb rubber asphalt specifications in future projects.
