Finalization of Guidelines for Maintenance Treatments of Pavement Distress (0-4395-2)

This research project focused on developing guidelines to aid less experienced maintenance personnel in selecting repair methods and materials for treating pavement distress. The first phase of this project is detailed in Research Report 0-4395-1 and included a literature review, visits to field sites, and laboratory ;ting with common materials used for maintenance base repairs. Based upon the findings from the work completed in Phase I, a field guidebook was drafted for use by maintenance personnel to aid in selecting a repair strategy based upon distress type, distress severity, and importance of the road. This report describes the remaining phase of the project. With TxDOT personnel, the research team visited several locations in need of maintenance treatments and documented what treatment would be recommended from the draft field guide. The research team also noted the treatment planned by the TxDOT maintenance supervisor. In this manner, the recommendations from the draft field guide were checked to ensure they were relatively consistent with the state of the practice within TxDOT. Based upon the findings and comments received, the research team made some minor changes and additions to the draft field guide to finalize the guide for publication and distribution. The final version of the guide is available as Product 0-4395-P2.
