Minneapolis expects to repair three to four miles of concrete streets each year through the Concrete Street Rehabilitation Program to stave off larger, more expensive reconstruction. Techniques include slab stabilization, full depth repair (FDR) and partial depth repair (PDR), cross stitching longitudinal cracks and crack resealing.

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. 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.

Concrete pavements have historically out performed other pavement types on a length of service life basis. With growing public concern about highway noise, existing concrete pavements must be made quieter. By maintaining the concrete surface either with diamond grinding or a concrete overlay, the designer can address noise concerns and improve safety.

The longevity of any sealant installation is a function of the joint sealing design, the materials used, the workmanship of the installation, and the prevailing environmental and traffic conditions. One experiment included joint resealing. Sealant performance can be significantly improved through proper joint preparation for very little cost.
