The purpose of this Federal Highway Administration Demonstration Project was to evaluate the installation and performance of a section of I-81 in Botetourt County, Virginia, that was rehabilitated by concrete pavement restoration (CPR) methods. The seven repair techniques used were (1) slab replacement, (2) patching, (3) slab stabilization (4) surface grinding, (5) joint resealing, (6) subdrain installation, and (7) load transfer restoration. Although the individual repair techniques had varying degrees of success, CPR as an integrated system was generally effective in restoring the pavement's structural and functional integrity. It was recommended that the Virginia Department of Transportation routinely consider CPR as a viable alternative for pavement rehabilitation. It was also recommended that projects under consideration for restoration be carefully evaluated to ascertain whether their structural conditions render them suitable for CPR.

The state of the art of Portland cement concrete pavement evaluation is reviewed with emphasis on the methods applicable to the urban freeway environment. Methods are recommended for texture evaluation, void detection and condition surveys. Data analysis methods useful for the development of pavement performance models are presented. The overall framework for life cycle cost (LCC) analysis is described with recommendations for the development of a LCC method for the Arizona Department of Transportation.

Concrete pavement restoration (CPR) techniques have gained greater national significance as DOT agencies attempt to further extend infrastructure service lives prior to required major rehabilitation or reconstruction. Various publications have documented design procedures and materials for CPR techniques, but less has been written about best practices for their construction, based on information from contractor and DOT agency practitioners. This report consolidates best practice case studies for six CPR techniques: cross-stitching, dowel bar retrofit, diamond grinding, full depth repair, partial depth repair and slab stabilization. Technical briefs for each CPR case study have also been written to accompany the main report. They have been separately published.
