Does asphalt crack in cold weather?

Especially during times of heavy snowfall and snow melt, the expansion and contraction is simply too much for the asphalt to absorb, leading to ongoing cracking.
How can we prevent road potholes?
Slow down on rough roads to give you a better chance to avoid any potholes. Higher speeds reduce reaction time and control. 9. Slow down when you must drive through a pothole but get off the brakes just before encountering the pothole.

Why does concrete crack in cold weather?
As the water in the concrete freezes, it expands and then thaws as temperatures fluctuate. This process stresses the concrete and causes cracking. The result of the repeated freeze- thaw cycles can be surface spalling (flaking) and widening cracks that usually don’t emerge until the spring.
What does road salt do to roads?
It accelerates corrosion by damaging concrete and metal bridgework, and it promotes rust on cars. If it washes onto the ground alongside the road or gets into fresh water, it’s harmful to plants and wildlife. It’s estimated that some five million tonnes of salt are spread on Canadian roads each year.
What causes the most damage to roads?

What does ice do to asphalt?
Understanding the Freeze / Thaw Cycle As water freezes, it expands, which is not ideal for your driveway, parking lot, or roadway. Expanding water can cause damage to asphalt pavement in the form of expanding cracks and crumbling. Moreover, a compromised asphalt surface can break apart, causing potholes to form.
