Can heat pumps prevent potholes?

Researchers at the University of Surrey have developed an innovative solution to tackle the persistent problem of potholes caused by freezing and thawing during the winter, which could significantly improve the state of major roads across Britain.

Potholes are created by three main factors: First, road surface cracks develop due to traffic. Second, water enters these cracks. Lastly, in winter, this water freezes and expands, widening the cracks before eventually thawing. This repeated process weakens the road material, resulting in deterioration.
