The Strategic Highway Research Program (SHRP) project H-106 has initiated an investigation of the cost-effectiveness of materials, equipment, and procedures used to perform several routine pavement maintenance activities: pothole repair in asphalt pavement, crack treatment (sealing and filling) in asphalt pavement, joint resealing in portland cement concrete (PCC) pavement, and partial-depth spall repair in PCC pavement. The project provided for test site installations of all four maintenance activitities at locations across the United States and Canada. Data collected during the installation procedures, as well as survival and distress development data collected during subsequent evaluations, have been compiled into one of the most comprehensive data bases on these pavement maintenance topics. While performance evaluations will continue to accumulate data under a future Federal Highway Administration (FHWA) project, this report presents the results of the analyses to date. This volume provides an overview of all four repair projects, including the development of the initial testing and evaluation plans, volumes II through V present each of the individual experiments in greater detail.
