Abstract:The deterioration of jointed portland cement concrete (PCC) pavements on the interstate system in Virginia has created a need for full-depth and partial-depth repairs. In this report, efforts related to full-depth repairs are described and discussed, Such repairs have utilized both cast-in-place and precast materials. Rapid and permanent repairs have been achieved using procedures as stress relief, cast-in-place restoration, precast replacement, and cast-in place replacement. It is recommended that these procedures be continued as warranted by pavement repair needs. They should be used with detailed guidance in both state force and contract work. In repair work, assurance should be made that the supervisors and inspectors are not only knowledgeable of the recommended procedures but also are aware of potential problems that can result from faulty applications. Where poor drainage has contributed to pavement deterioration, improvement of drainage facilities and the use of pavement undersealing should be a part of the total rehabilitation effort to assure a satisfactory service life of both existing and repaired pavement segments.
