Futureproofing Victorian roads requires governments to think out of the box

Futureproofing Victorian roads requires governments to think out of the box

The Victorian premier recently acknowledged that more could be done to construct and repair roads across the state. As an RMIT engineering expert explains, longer term solutions could be delivered by exploring innovative technologies and advanced construction techniques.

“As an established road network matures, increased resources are inevitably needed to maintain it. Moisture is the main enemy; keeping water out or ensuring adequate drainage is critical to longevity.

“Recent intense rainfall events have contributed to deteriorating road infrastructure. In the case of potholes, the cracked surface allows moisture to enter and pool beneath the pavement, which causes it to lift under traffic loading.

“It’s worth remembering that much of our road network is managed by local governments.  Routine maintenance is essential for effectively managing this infrastructure and addressing defects as they arise, which will prevent them from becoming a major hazard that requires costly repairs.

“Roads are crucial for connecting communities and facilitating the efficient movement of people and goods, which in turn drives economic development. The function of a road is to ensure ‘good ride quality’, so the trip is comfortable for all users. Conversely, poor conditions contribute to vehicle damage and road safety.

“There is a clear opportunity to leverage pavement research and expertise to improve the resilience of our road network. To achieve this, we must explore innovative technologies, advanced construction techniques, and effective monitoring systems to enhance road performance and durability.

“RMIT is leading efforts through its research on recycled and waste materials in pavements, modelling the impacts of climate change, and developing innovative technologies for proactive infrastructure management.”

Dr Jaspreet Pooni is a lecturer in civil and infrastructure engineering at RMIT University. His recent research has focused on road integrity and performance.
