A PROCESS FOR SELECTING STRATEGIES FOR REHABILITATION OF RIGID PAVEMENTS

This digest summarizes the findings of the research conducted under National Cooperative Highway Research Program (NCHRP) Project 10-50A on the process for selecting strategies for rehabilitation of rigid pavements subjected to high traffic volumes and describes a process to help state highway agency decision makers identify the most appropriate maintenance, rehabilitation, and reconstruction (MRR) strategy for specific project conditions. Because the selection of a specific MRR strategy is influenced by many factors, detailed guidelines were not developed. However, the research evaluated different highway agency processes for pavement analysis and design and developed an integrated MRR selection process that considers both pavement-related aspects of the strategy and non-pavement-related aspects.
