What does Norway do to prevent frost-heave on its roads?
I used to date a girl who did soil sampling for paving/construction projects with the sole purpose of delaying environmental effects as long as possible (as it is, obviously, expensive to re-pave). You’re underlying soil mixture is key in dealing with a lot of weather related problems (regardless of cold/hot, wet/dry etc.) in that it can either keep moisture in or out, help with expansion and/or contraction, and simply support the amount of rock on top. I did a Google search for frost-heave and this was the first link. Appropriately, it’s from a site called pavement.com.
Ottawa, Canada has a wide temperature range. When I stepped off the plane on December 30th, it was -40C with the windchill. When I left in late August, it was +40C with the humidex. Ottawa has pioneered special sewer hole covers, follows salting guidelines, etc. Over in Quebec, they’re experimenting with pavement structures. You might have some luck Googling for frost heave and limiting the results to pages from Canada (www.google.ca). Many parts of Canada are subject to temperature extremes and frost heave has been important to our transporation infrastructure as far back as the development of the national railway in the 1800s. Also, if you Google for Canadian examples, most of them should be available in English, as opposed to docs from Norway, Russia, etc.
