Abstract:

As expected, most state and provincial DOTs that we spoke with are using traditional methods to prevent and ; remove snow and ice at very low temperatures. In addition to a review of current research, we spoke with six winter ; maintenance professionals at state and provincial DOTs with cold climates, including Maine, Ontario, Alberta and ; Manitoba. ; The most innovative strategy in use among these agencies is the hot-water sand spreader being tested by the Ontario ; Ministry of Transportation. Originally developed in Europe, the spreader delivers sand that is prewetted with hot ; water (about 200 F). This technology is designed to keep sand on the road for much longer than conventional sand ; spreading techniques. ; Norway has also tested the use of hot water as a prewetting agent for salt, and one article about this research noted ; that testing was planned to assess how this technique affects the temperature limits of salt application. ; Other strategies identified that may be less common include constructing snow ridges rather than snow fences to ; control blowing and drifting; and for areas where snow storage is required, use of an in-traffic loading technique that ; minimizes lane closures.
