CPB Contractors projects, Logan Motorway and Gateway Extension Motorway are vital transport links that connect Logan with Ipswich in the west and the Gold Coast in the south, as well as the Port of Brisbane and Brisbane Airport.

CPB Contractors has marked an Australian first on the Logan Enhancement Project, using an innovative EME2 (Enrobé a Module Élevé Class 2) asphalt product that increases paving durability, despite requiring a lower volume of the product in comparison to regular asphalt. 

Selected for its high strength and resistance attributes, more than 206,000 tonnes of the combined base and binder asphalt was applied to the Queensland roads project. The Infrastructure Sustainability Council of Australia (ISCA) has since verified that this is the single largest commercial use of EME2 in Australia. 

David Fox, CPB Contractors Group Sustainability Manager, considers the use of this new material as another example of CPB Contractors’ commitment to sourcing innovative and environmentally sustainable solutions for projects. 

EME2 can potentially reduce the layer thickness of the base course for a heavily trafficked pavement by up to 30% depending on traffic conditions and local climate, delivering construction program savings.

“Longer-lasting pavement solutions and more durable design will pay dividends by reducing the frequency of road resurfacing in years to come. 

“Innovations like this are contributing to the broader market transformation of sustainable road construction by minimising future road maintenance and disruption for vehicles.”

The use of EME2 asphalt, combined with other sustainability initiatives including fauna crossings and energy, water and waste reductions have contributed to the project’s overall ‘Excellent’ ISCA rating.

Challenging the status quo delivers a competitive edge in Western Australia

Nayelly Garcia is a Senior Estimator with CPB Contractors (Western Australia/Northern Territory) who has taken a leading role in the delivery of more than $2 billion of Perth’s major road alliances, including Gateway WA and most recently the Metropolitan Road Improvement Alliance (MRIA).

For more than three years, Nayelly has priced almost 2 million square metres of pavement, and guided the MRIA pavement design team to explore innovative design solutions, while meeting industry standards for Main Roads Western Australia.

Pavement costs are often more than 40% of the overall direct cost of road projects. By proposing alternatives on two high profile Western Australian infrastructure projects, Nayelly and the pavement design team have achieved major cost savings, while minimising driver disruption on Perth’s most congested road networks.

Innovations in paving are central to CPB Contractors’ road projects. Specialist machinery has been built to deliver some of Australia’s most significant infrastructure projects, including delivery of the twin tunnels on Sydney Metro Northwest, Brisbane Airport’s parallel runway, and the Woolgoolga to Ballina upgrade.
