During the winter months, it is usual for more damage to occur to the surface of roads than at any other time of the year.
Significant damage is also done to the highway network by heavy and prolonged periods of rainfall.
While serious defects are repaired, the rainfall can cause minor cracking of road surfaces. Where water is been able to penetrate the road surface, the lower temperatures experienced during the winter months can lead to the formation of ice which then expands and creates damage. Potholes in particular form more frequently during these winter months.
We monitor this type of road surface damage as part of our routine inspections programme and also when potholes or other damage is reported to us.
