Answer 1

The old joke is that there are two seasons in the cold places, winter and roadwork.

There’s also frost heave and frost quakes.

When the ground freezes deep enough fast enough the water expands and the chunks fracture and heave upwards to reduce the pressure. This is why roads and paved areas need so much repair work in cold climates. It’s being fragmented from below for half the year. Proper drainage and roadbed layering help but water is everywhere.
