World-first technology is being used to assess the condition of the Victoria’s flood-ravaged roads as part of the State Government’s emergency road repair blitz.
Minister for Roads and Road Safety, Melissa Horne said the Australian Road Research Board’s Intelligent Pavement Assessment Vehicle (iPAVe) will join the blitz, assessing the condition of more than 8,400 kilometres of Victoria’s roads in the wake of recent floods and extreme rainfall, gathering a broad spectrum of data.
The collected data will help plan for upcoming large-scale repairs and road maintenance across both regional and metropolitan Victoria, she said.
“We’re using the latest technology to make sure we deliver the repairs needed right across our roads following the devastation caused by recent floods and extreme rainfall,” the Minister said.
“Already, crews are making a start on delivering large-scale, long-term repairs and this data will help to plan for further works, ensuring that the communities hit hardest by these floods remain connected to vital supplies and services.”
Equipped with a range of data collection systems, iPAVe is capable of assessing both the structural and functional condition of the road, using laser technology developed in Denmark to look at characteristics including roughness, surface texture and rutting.
Cracking and other surface data is assessed using an automated 3D monitoring system, while cameras mounted to the truck’s exterior will give road maintenance experts a first-hand look at the state’s road network.
Thanks to an on-board ground-penetrating radar, the iPAVe can also collect sub-surface data at the same time, giving experts a better understanding of what’s happening underneath the road surface.
These datasets are collected at the same time, in one trip, at highway speed, making the iPAVe a cheaper, faster and safer way to collect intelligence, the Minister said.
Data collected as part of iPAVe’s most recent assessments will then be compared with similar information collected in 2021 to gauge the full impact of the recent floods, she said.
More than 170 of the state’s roads will undergo inspection by iPAVe, including major freight and tourist routes like the Hume, Western, Midland, Goulburn Valley and Calder highways.
