Why haven't Canadian Cities pounced on the concept being utilized in Northern European Cities? I am lobbying city councillors in Winnipeg to consider it. The upfront costs are higher but the amount saved is far more in the long run.
-No Heave because there is no freeze/thaw as the temperature remains constant (above 0).
-Less accidents
-Less construction costs
-Less painting as stickers could be used since the plows wouldn't rip them off, which brings me to my next point, my biggest pet peave:
-No bloody plows.
-No Salt (degrading cars and killing plants, spilling into waterways etc)
-No sand, no mess.
-Less slipping and falling.
Etc. Etc.
This is being utilized in Europe, so there is no reason for people to say that it can't be done.
Example cities are Michigan in Holland or Oslo in Norway.
