MELBOURNE-BASED ASPHALT PRODUCER CITYWIDE ASPHALT GROUP HAS RECENTLY EXPANDED ITS GREENPAVE™ PRODUCT RANGE, ADDING A NUMBER OF SPECIALTY MIXES WITH A HIGH RECYCLED CONTENT. OPERATIONAL IMPROVEMENT MANAGER TIM OGUN TALKS ABOUT THE COMPANY’S VISION FOR A GREENER PAVEMENT INDUSTRY.

hen Citywide flipped the switch at its cutting-edge Laverton asphalt plant in March last year, COVID-19 had just arrived in Victoria, and the prospects for the local economy – let alone the construction sector – were looking increasingly uncertain. Fast forward 18 months and the company, which also runs a busy production facility in North Melbourne, is preparing to launch the eighth product under its flagship GreenPave™ green asphalt range to the market, with research and development going strong within the team. Tim Ogun, Operational Improvement and Business Development Manager at Citywide Asphalt Group (CAG) says the recent diversification of the GreenPave range follows increased demand for ‘green asphalt’ products within the
industry, as well as added capabilities with the launch of the company’s Laverton site. CAG is a 50-50 joint venture between Citywide and Fulton Hogan, which was formed in 2016. The joint venture launched a new plant in Laverton using the Marini Asphalt Plant, a batch plant capable of producing a wide variety of asphalt mixes at up to 200 tonnes per hour. The Laverton plant is also designed for low-emission production, using an efficient ‘blue smoke’ system that reduces both emissions and odours. The plant is also Melbourne’s first asphalt production facility powered by 100 per cent renewable electricity as part of the Melbourne Renewable Energy Project. “Citywide has been industry-leading with the production of low-emission warm mix asphalt products from our North Melbourne facility for many years. But with the launch of our Laverton asphalt plant, we have been able to incorporate a wider range of environmentally friendly products into our asphalt mixes,” says Ogun, who has worked as project
manager with Fulton Hogan for 15 years before moving to CAG in 2016. “With Fulton Hogan’s full technical support, all of our new asphalt products are tested extensively in the labs. This has helped fast-track our research and development process to deliver products with higher recycled content,” he adds. A LOOK AT THE GREENPAVE RANGE Having started with the GreenPave warm asphalt mix produced at Citywide’s North Melbourne plant for the past five years, the GreenPave range today incorporates seven other specialty products, each with a high percentage of recycled content. Each of Citywide’s GreenPave products is identified with a suffix denoting the type of recycled product used within the mix. For example, the CR in GreenPave CR stands for crumbed rubber and the mix is manufactured using highly engineered crumbed rubber as binder. “Citywide has supplied its GreenPave CR for municipal projects in southwest Melbourne and on several other projects. After multiple applications, not a single defect has been recorded,” says Ogun. GreenPave HR is another product in
Citywide Asphalt Group’s Marini Asphalt Plant in Laverton, Victoria.
