Commenting on Alaskan Highway - I used to live in 4-seasons and know what winter can do to the roads. IMHO the Alaskan Highway was poorly build to start with. You have nice stretches of smooth asphalt for few miles and then build "speed bumps" that will get you airborne at 60 mph. Evidently different crews build different stretches. Than don't see any surface repairs done. Whenever there are cracks, or other pavement build flaw, they dump few tons of gravel, set warning signs and call it the season.
Kind of sucks as 40 years ago somebody invented an asphalt truck, who could make the patches driving 40 mph. But that technology never got here.

OK, but did you live in the parts of Alaska or Canada with permafrost, where the subsurface is frozen year-round? Have you driven Alaska roads in winter, then spring. The roads are generally ok, except for surface ice, as long as they stay frozen. But when the surface layer of permafrost begins to thaw, then refreeze, the frost heaves form. The heaves have everything to do with climate and nothing to do with highway technology. So, no Alaskan even tries to go 60 mph on those roads once the heaves form, especially in an RV.
