Ten-Year Field Performance Evaluation of Joint Reseating Project

In 1989, the U.S. Army Engineer Research and Development Center and Crafco, Inc., initiated a research effort to develop improved materials and processes for sealing and resealing joints in portland cement concrete pavements. The objectives of the research were to develop specification limits for improved field performance of hot-applied, jet-fuel-resistant (JFR) and non-jet-fuel-resistant (non-JFR) sealants and obtain field data to determine the field performance of different sealants and installation configurations. The research effort was divided into a laboratory phase and a field phase. The laboratory phase focused on identifying ideal properties that a hot-applied non-JFR and hot-applied JFR sealant should possess, evaluating commercially available sealants to determine if they exhibited those properties, and developing improved hot-applied materials that would exhibit as many of those properties as feasible. The field phase was initiated in June 1991 at Fairchild Air Force Base near Spokane, Washin...
