This paper presents the results of an extensive field study of the comparative performance of road salt on different pavement types for snow and ice control in transportation facilities. Approximately 400 tests were conducted in a real-world environment, covering three different pavement types and 27 snow events. The performance is compared on asphalt concrete (AC), portland cement concrete (PCC), and interlocked concrete (IC) pavements in terms of pavement clearing speed. The study suggests that on average, salt performs better on AC than PCC or ICC pavement, with the latter two having similar performance. The results were confirmed with a paired t-test analysis and then used to develop a performance model, the results of which were used to develop an adjustment factor for each of the different pavement types. The results from this research can be applied by pavement maintenance personnel to optimize salt usage and improve safety in transportation facilities. [ABSTRACT FROM AUTHOR]

This paper describes an empirical study aimed at investigating the performance of the anti-icing strategy for snow and ice control of parking lots and sidewalks. The research is motivated by the need to address several key questions concerning various operational decisions related to the anti-icing strategy, including its relative effectiveness under different weather and site conditions, treatment options, and optimal application rates. Extensive field tests were conducted under traffic controlled environment and variety of weather events using regular solid road salt, brine, and two other liquid alternatives. Data collected from these tests was used to analyze the performance of anti-icing operations such as friction level, bare pavement regain time, and the effects of various external factors such as pavement temperature and application rate. The research has concluded with findings that are directly applicable in real world winter maintenance practices. [ABSTRACT FROM AUTHOR]
