Abstract: Rehabilitation studies have been conducted on Interstate 95 in Duval County, Florida. The rigid, unreinforced pavements were constructed in the late 1950's and 1940's. Investigation and analysis has been performed. Investigation included review of project documents, condition survey, and in-place testing to evaluate existing design, condition, dimensions, and properties. Evaluation has been conducted with respect to cracking and reseating pavements, selective slab replacement, pressure grouting, routing and sealing, and resurfacing of existing pavement. The paper also presents the design approach, estimation of design parameters, and the preliminary results of design. The United States Corps of Engineers methods were utilized for portland cement concrete and asphaltic concrete overlay design.
