Snow and ice control strategies and tactics that employ solid and liquid chemicals, abrasives, and mechanical methods--individually or in combination--have been used by many different highway agencies throughout the world. Research by the Strategic Highway Research Program, the Federal Highway Administration, the National Cooperative Highway Research Program (NCHRP), and other organizations in the United States and other countries has addressed many of the issues associated with snow and ice control treatments. However, widely accepted guidelines for selecting level of service driven roadway strategies and tactics for specific weather, site, and traffic conditions have not been developed. Without this information, the process of selecting treatment strategies and tactics that meet highway agencies level of service objectives is difficult. Five snow and ice control strategy and tactic combinations were tested and evaluated over several years with various ranges of weather, site, and traffic conditions found in North America as part of NCHRP Project 6-13. A pavement ice condition index was developed for determining the overall effectiveness of a given snow and ice control strategy and tactic combination as well as effectiveness of within-storm and end-of-storm winter maintenance operations. The field test results are being used to develop a set of guidelines for selecting roadway strategies and tactics for a range of winter maintenance operating conditions. The results will also be used in developing snow and ice control material application rate guidelines. The results of this effort will be published by NCHRP in the near future.
