How do potholes form?

Potholes form through freeze-thaw cycles. First, water enters the pavement through cracks and pores, softening the underlying soils. Next, the water freezes causing it to expand (think of making ice cubes in your freezer), pushing up the pavement, which will create more cracking. This stresses and weakens the pavement. After freezing, the water under the pavement melts and dries out. This leaves a hole beneath the pavement. As vehicles drive over the pavement, the weakened pavement cracks and falls into the hole, creating a pothole.

Why, when we patch a pothole, does the fix not last?

The materials used to fill potholes stick the best during warm and dry conditions, which isn’t always feasible. Potholes are created by water entering into the pavement during freeze-thaw cycles. Once a pothole is patched, the edges from the patch and the existing pavement are now new areas for water to enter the roadway. This will cause the process to repeat over time.
