Weekly report on roadworks
Get our weekly report on potholes that have been fixed, across the City...
It’s going to take some time to fix Council roads, given we have had two years of unprecedented rainfall. This is currently the case throughout much of NSW, where many councils are dealing with extensive damage to their road networks. And it's not just the saturated roads that are the challenge, there are supply chain issues and a battle to secure extra resources as local and state governments all currently need the same assistance.
Why are there so many potholes?
Most people will have a pretty good idea that lots of rain means more potholes on our roads. But do you know why that’s the case?
Potholes form when the asphalt surface of the road breaks up. This can happen because the asphalt is older, or when too much water gets into the road’s pavement layers.
Potholes can vary in size and shape, but they often have something in common – rain, or more precisely, water. After lengthy periods of rain, like what we’ve been experiencing for the past two years, some road pavements become saturated. The water in the pavement is compressed under the weight of traffic and this compressed water pops out any weak point in the asphalt forming a pothole.
Another way they can form is if the asphalt already has some cracks. Cracks make it easier for water to get in and soften the pavement. This leads to more water getting in, more cracking, and the cycle accelerates. Eventually, pieces of the surface will pop out, forming a pothole.
