In response to a request from the Research Division, a research proposal entitled "Sealing Cracks in Flexible Pavements" was presented to the Oklahoma Department of Transportation in February, 1976. This proposal was for a three year study to begin July 1, 1976. The proposed study was primarily devoted to evaluating the effectiveness of various materials and methods of application for sealing flexible pavement cracks. Secondary objectives of the proposed research included developing crakc survey and monitoring techniques, measuring pavement movements at crack interfaces and establishing criteria for crack sealing operations and the selection of sealants. construction, and performance of the latest methods for restoration of Portland cement concrete pavements (PCCP). The CPR techniques demonstrated included full depth repair, spall repair, undersealing, restoration of load transfer, diamond grinding, and the resealing of all joints. This is the final evaluation of the project.
