Well you learn something new everyday! Yes they call them frost heaves here too and I never heard that before. We have alot of frost damage to roads up here also. We are in a valley which holds onto the the moisture and Ontario Transport uses salt(and I mean ALOT of salt) on the roads here due to ice storms like today. The salt and the moisture causes some really bad potholes. Due to the snow removal trucks which also destroy the roads you can see some bad potholes. I must say the City is really good about getting out and at least identifying them and marking them off so you dont lose your car in one. Now out in ALberta the roads were beautiful. Its so cold and a dry climate they have no moisture and rarely do you see any ice storms and only sand is used on the roads they have it nice out there. What a difference it makes.
