I do not live in a region with lots of snow or ice. Would there be any concern about melting the closest 'layer' of snow over pavement and creating a snow 'shell' over the road? If an area is getting sufficient ice precipitation I wonder if such a system could keep up and what the dangers would be of a road that was not salted/sanded in this condition.
