Abstract:This report summarizes the results of a research task that was conducted to document the Ohio Department of Transportation (ODOT) current state-of-the-practice for crack sealing, identify best practices used or researched by state DOTs for crack sealing, and identify new methods and equipment for crack sealing that can improve the efficiency, response time, and safety of maintenance crews. To achieve these goals, a comprehensive literature review of all studies on the best practices for improving the efficiency and safety of crack sealing installation was conducted. In addition, surveys were performed to gather information from DOTs and local public agencies. Robotic Maintenance Vehicle (RMV) was identified as an equipment that might help improve the efficiency of crack sealing operation and workers safety. However, currently there is not enough information or experience with using this equipment to validate its capabilities or benefits. The results of cost analysis conducted in this study indicated that RMV may result in reducing the cost of crack sealing for ODOT. However, the RMV cost savings depend on several assumptions made that could not be validated at the current time. Therefore, all assumptions made need to be verified before making final conclusions on the RMV cost effectiveness and its benefits to ODOT.
