Roads - potholes
Defects will arise on the highway, particularly as more traffic causes more wear and tear. The highway condition can also be damaged by accidents, misuse and the impact of severe weather in particular flooding, snow and ice.
When a defect is identified on an inspection or is otherwise reported to us, the type of maintenance required is assessed.
Potholes are the most commonly occurring defect on the highway. There are few reported that present an immediate hazard but those that are identified of this severity are made safe within 24 hours. Over the last four years we have seen the number of winter potholes steadily increase.
A pothole develops where the surface of the highway has failed. This allows the entry of water, disintegration and the removal of material by traffic at weakened spots on the surface. Eventually this causes a hollow, commonly referred to as a pothole, to appear in the highway surface.
