Australia's floods of 2010-11 spread devastation and damage across Queensland, with 33 people losing their lives and causing billions in losses across the state. The floods also damaged 19,000km of roads, including those needed for emergency and delivery vehicles.
It was a stark lesson in the importance of weather-proofing Queensland's most vulnerable roads, to ensure that future flooding would lead to fewer people being cut off.
Since then, Queensland has been using a process called foamed bitumen stabilisation.
This injects small amounts of air and cold water into hot bitumen, the sticky dark substance typically used for road surfaces.
The bitumen then expands and forms a water-resistant layer.
The result is a stronger yet flexible road surface or pavement that is better able to withstand flooding.
