Abstract:

One of the challenges that faces the winter maintainer is how much chemical to apply to the road under given conditions. Insufficient chemical can lead to the road surface becoming slick, and the road becoming unsafe. However, too much chemical can also be bad. While an excess of chemical will ensure (in most circumstances) that a safe road condition is achieved. It may also result in a substantial waste of chemical (with associated costs for this waste) and in ancillary damage to the road itself and to the surrounding environment. Ice may appear on the road as compacted snow ice, refrozen ice, or atmospheric ice. In addition to examining how ice type effects the extent to which ice adheres to the pavement, this study also examined how various rates and types of de-icing chemical application effects the scraping resistance of ice on the pavement. Specifically, solid salt (sodium chloride), solid calcium chloride, and a liquid salt solution or brine were tested at different quantities of application, and also for different delay times after application.
