Interesting. There is a lot more ashpalt here, in Canada. I suspect it is due to frost, and "frost greaves", which can buckle and damage even concrete roads.

Asphalt is cheaper, and replaced more often, so degradation due to frost greaves and such is not as fiscally damaging. But my entire point is, by placing sensors during normal resurfacing, it literally is a small task.
