The roads here deteriorate fairly fast also, since the high clay content in the soil soaks up water and expands, dries out and contracts and cracks the roads. It's a good way to speed up the pothole process. Same reason why a lot of older properties have houses on a mean slant.

It is somewhat true about older houses, my house is 80 years old and does move due to freezing of the perimeter walls while remaining warm around the interior pads in the winter. Most roads that I have investigated have 1' to 4' of granular base materials underneath them and the clay has very minimal effect under typical conditions. The service life of roads being exceeded by ten years is usaully a good reason they fail. My wife is a soils engineer and ok'd this post.
