本文介绍了对交通设施防雪防冰替代材料性能进行比较的广泛现场研究结果。在真实环境中进行了大约300次测试，涵盖了四种替代材料和21个雪上项目。在融雪性能--裸露路面恢复时间方面，每种被测试的替代品都与普通的岩盐进行了比较。这项研究证实了这些替代品相对于普通盐的相对优势，但也表明它们的性能在很大程度上取决于一些外部条件。对性能模型进行了校准，然后用于开发施用量调整系数，维护作业可以应用这些系数来确定特定天气事件和路面状况的最佳施用量。结果的适用性仅限于没有交通影响的停车场和人行道，因此不能很容易地应用于冬季道路养护。
This paper presents the results of an extensive field study on the comparative performance of alternative materials for snow and ice control of transportation facilities. Approximately 300 tests were conducted in a real-world environment, covering four alternative materials, and 21 snow events. Each of the alternatives tested were compared to regular rock salt in terms of snow melting performance — bare-pavement regain time. The study confirmed the relative advantage of these alternatives over the regular salt, but also showed that their performance varied largely depending on some external conditions. Performance models were calibrated and then used for developing application rate adjustment factors that can be applied by maintenance operations for determining the optimal application rates for specific weather events and pavement conditions. The applicability of the results is limited to parking lots and sidewalks without the traffic effects, and as such cannot be easily applied to winter roadways mainte...
