This report summarizes the results from a three year research project entitled “Snow and Ice Control for Parking Lots and Sidewalks (SICOPS)”. The document highlights the important findings from the project along with a number of recommendations that can help maintenance contractors and government agencies develop a cost-effective winter maintenance program for snow and ice control of parking lots and sidewalks. The report is intentionally brief and concise so that it can be easily followed by winter maintenance personnel in the field. Detailed discussions on the test results and the underlying methodology are reported in various technical papers listed at the end of this report.
Over the project period, the project team conducted an extensive review of relevant literature, a comprehensive survey of facility users, maintenance contractors, and government agencies, and a large scale field experiment on a wide range of strategies, methods and materials. The field tests were conducted at a parking lot and several sidewalks located in the City of Waterloo, Ontario over three winter seasons. Approximately 5000 tests were conducted over nearly 100 winter snow events, covering a large number of treatment combinations in terms of material types, maintenance strategies, and treatment techniques under a wide range of winter weather conditions. The field data were then analyzed systematically using various statistics for generating quantitative information about the effects of various factors on the snow melting performance of different materials, rates and treatment methods. The major outcome of this effort is a decision support tool for the selection of the most appropriate maintenance strategies, materials and application rates to address the specific maintenance needs of any parking lots and sidewalks under any winter events.
