Managing Pavement Friction of Wyoming’s Roads Considering Safety

The main goal of this study is to enhance road safety in Wyoming by integrating a crash risk mitigation approach into the pavement friction management program. This goal can be accomplished by performing the following tasks: (1) Investigate the relationship between pavement surface friction and friction-related crashes in Wyoming. (2) Define the best practices of maintaining pavement friction levels using bonded aggregates and surface treatments. (3) Implement a data-driven approach to select friction related maintenance strategies. (4) Estimate the potential reduction in friction related crashes due to the enhanced maintenance activities, which consider the restoration of adequate pavement friction levels. (5) Develop a detailed methodological framework for implementing pavement friction treatments for WYDOT considering safety implications. (6) Determine the cost-effectiveness of the proposed pavement friction management plans in terms of crash reduction benefits and associated maintenance costs. (7) Propose an enhanced pavement management policy for WYDOT considering friction treatment plans to ensure safe traffic operations.
