Developing innovative solutions
We use innovative transport technologies to address current and future network issues. Find out about the research and partnerships we’ve used to improve the quality of our road network and increase its lifespan.
We have partnered with the Motor Accident Insurance Commission, Queensland University of Technology, Griffith University and the University of Queensland in the $3.3 million Transport Academic Partnership.
This agreement lets all parties work together to perform strategic research and development. This helps local universities to build capability in the transport sector and allows all participants to build up and use a larger body of research.
We partner with the Australian Road and Research Board in the National Asset Centre of Excellence. This partnership allows us to save money on performing targeted research that will benefit all members. The Centre of Excellence has a strong focus on pavements, the use of innovative materials, and translating new knowledge into best practice.
We invested $4.8 million in 2018 to fund a number of multi-year projects. These projects include:
- increasing the use of recycled tyre rubber in road resurfacing
- beginning large pavement works that use a more cost-effective alternative to asphalt called high modulus asphalt, or EME2
- using precast geopolymer elements as an alternative to cement concrete to improve durability and reduce carbon footprint.
Our research and design work has led to the introduction of high modulus asphalt (also known as EME2) to Australia. This new substance allows us to use a base thickness 20% less than conventional asphalt for motorways and other roads with heavy traffic. It also offers superior performance, sustainability and productivity in construction time.
- 53,000 tonnes of EME2 have been used on the Port Drive Upgrade Project for Port of Brisbane.
- 6,000 tonnes were used in a project for Steve Irwin Way on the Sunshine Coast.
We worked with Quickcell Technology Products and ARUP for 3 years to develop a way to save money on bridge construction by using larger bridge girders. Because these girders are longer than the current Super-T girders, they save money on bridges over rivers and rail corridors because fewer piers are needed.
After the successful trial of the Quickcell Super I-girder on the Port Drive Upgrade project for the Port of Brisbane in 2017, this product is now available to use on other projects.
