| 摘要： | The primary objective of winter maintenance operations is to improve traffic safety and efficiency during winter storm periods. Abrasives and salt brines have been successfully applied to increase traction and prevent snow and ice from bonding to road surface. However, because of some undesired side effects, such as corrosion and damage to the environment, salt and abrasives may need to be supplemented by other substances in some areas. Powerful non-corrosive acetate-based chemicals have been considered by several agencies, but their high price has limited their use. Recent research has focused on the use of new, less corrosive, and highly effective chemicals, such as liquid corn salt (LCS). This research project evaluates and compares the cost-effectiveness of using salt brine, and LCS on Nebraska highways. Field studies were conducted during the winter of 2002-2003 on two highway sections in Nebraska. Available field data included weather information, chemical use, time to achieve bare pavement, and maintenance log records. A benefit-cost analysis was performed to determine the cost-effectiveness of each treatment alternative. The operational benefits were the savings in road user costs resulting from reduction in travel time and delay. |
