Pothole prevention is a major and ongoing priority for us. Techniques include resealing, rejuvenation and pavement rehabilitation.
To reduce potholes occurring in the same location, Council identifies trouble spots and our teams use ‘heavy patch’ repairs, which involve rehabilitating a broader section of road and resealing it to significantly reduce the possibility of it happening again.
Sometimes, however, a road in poor condition may not be suited to heavy patching, given the extent of failed pavement.
We also use a risk-based analysis to determine when a ‘heavy patch’ is required - for example if a pothole or other type of road failure is located in a high traffic area.
To repair potholes during rain, we use a product that sets in the wet to increase safety as quickly as possible.
Heavy patch solutions may be rolled out at these locations later based on risk and analysis of other safety and asset factors.
