![]() ![]() Solving this issue would require calibrating the gradient of the road.Ī further issue is using the wrong grading of aggregate during the repair. If drainage is inadequate, then water will inevitably find its way back underneath the road surface. Poor drainage on the road is another reason for recurrence. Solving this issue requires digging up the roadbed, but this is typically ignored. If the substrate is unstable, usually caused by variations in moisture content of the ground beneath, then potholes are likely to reoccur. Councils will simply attempt to remedy the issue by filling in the cavity, but this is only part of the picture. The main issue is that filling in the pothole is often treating the symptom and not the cause. The UK government commits millions of pounds each year to maintaining and improving our roads, yet many potholes continue to resurface no matter how many times they are filled. Overall, Vanarama disclosed that over 100,000 complaints had been reported to councils across the UK in just one year. A survey by Vanarama discovered that the following UK councils received the highest amount of pothole complaints: ![]() It feels like there’s a pothole on every road you drive on, but the reality is that some areas of the UK have far more potholes than others. As vehicles pass over the bump, it eventually collapses, exposing the cavity. This causes the surface of the road to rise, creating a bump on the surface and a cavity underneath. When the temperature gets cold enough, the groundwater freezes and expands. Potholes are an unfortunate combination of water, poor road surfaces and cold temperatures.įirst, groundwater seeps into small cracks in the surface of the road. It seems as though more and more potholes appear every day, which begs the questions: what causes them? And why do they keep coming back? How is a pothole formed? In addition to giving road users a nasty jolt, potholes can cause significant damage to vehicles. Potholes are a scourge to drivers everywhere. ![]()
