摘要：	Beginning in January, 1997, an evaluation process was undertaken by the Maine Department of Transportation (MDOT ) in an effort to determine if developing technologies in the winter maintenance field might be viable and cost effective additions to MDOT’s current fleet of snow fighting equipment. This process included the evaluation of the following equipment: Case-Tyler Zero Velocity System, Swenson Precision Placement System, Compu-Spread Ground Speed Control System and the Dickey-john Ground Speed Control System. Data collected in both field and controlled settings indicate a savings in material is possible when utilizing some form of material metering equipment. Testing performed for purposes of material placement using Zero Velocity and Precision Placement systems also shows promise in producing material savings. Realization of these savings will require a significant commitment to equipment calibration and maintenance. It will also require a high level of coordination and cooperation between all personnel involved. In addition to the equipment evaluation, this report briefly discusses the Department’s experience with salt as a primary material for treating highways in winter related conditions.
