After a mild afternoon, this warmup could actually cause more potholes to form. This winter hasn’t been that bad, but we’ve already got so many problems. Why? Part of the reason we’ve had so many potholes is because of temperatures being inconsistant.
Potholes form this way:
- Water gets in cracks in the road
- When it gets cold that water freezes and expands
- Then when we warmup that ice melts
- A hole has been made in the asphalt from the expansion of the ice
- That hole often forms under the top layer of asphalt
Cars drive over that weakened asphalt with a hole underneath it, that asphalt then falls into the hole and you get a pothole.
The more freezing and melting, the more potholes you’ll get and we’ve had a lot of times this winter when high temperatures were above freezing, but low temperatures were below freezing and that’s what’s caused the problems.
