Radiator roads too hot for ice to handle

BLIZZARD-bound motorists won't have to wait for a salting truck or snow plough to clear the way if a "self-heating" road takes off.

While salting disperses ice and snow, the salty run-off corrodes the steel rods that reinforce roads and bridge decks, and also damages vehicles. With the US government striving to improve its road infrastructure after a fatal bridge collapse in Minnesota in 2007, new methods to clear snow without damaging structures are being sought.
