The performance and rehabilitation of jointed concrete pavements was recently investigated in a major national field study. Among the products of the research were detailed guidelines prepared to assist practicing engineers in determining when restoration was likely to be cost-effective, and when a structural overlay was required. The data base for this project included 95 sections of joint reinforced concrete pavement and joint plain concrete pavement in their first performance period. Thirteen of these sections were selected for use as case studies in rehabilitation strategy development. The sections were selected to cover the range of four major climatic zones of the United States, as well as a range of pavement conditions from good to poor (assessed on the basis of cracking, joint deterioration, joint faulting, pumping, and serviceability). The EXPEAR computer program was used to evaluate the current condition of each pavement section, predict its future condition without rehabilitation, and compare the predicted performance and cost-effectiveness of various rehabilitation strategies. The case studies demonstrated that restoration is the most cost-effective alternative for pavements that are structurally adequate and do not have concrete durability problems.
