Full depth repair (FDR) is a well-established technique applied to existing jointed plain and jointed reinforced concrete pavements (JPCP and JRCP) that includes both partial slab replacement and full slab replacement to address any variety of serious distress. FDR provides for the long-term repair of structurally and/or functionally deteriorated joints, working cracks, shattered slabs, and multiple slab distress.

By 1970, there were approximately 900 centerline miles of concrete pavement on the state road system in Georgia. Approximately 500 miles were built between 1960 and 1970 during the early years of the interstate highway construction era. It became evident by 1970 that there were significant problems with the early performance of these concrete pavements, specifically with joint faulting and slab cracking. The first use of diamond grinding in Georgia was a one mile section on I-85 in March 1976 done by maintenance forces. A second one mile section was done on I-75 in July 1976.

Belgium, a small highly populated country in Western Europe, has a long experience in the field of concrete pavements. The increasing concern came about regarding noise pollution. A better solution was being sought and found diamond grinding technique has been used for many years. This technique proved to be successful at all levels.

The objectives of the analysis were to determine composition of the slurry/concrete grinding residue (CGR), quantify each component and compare volume to maximum permissible limits for each component as established by the U.S. Environmental Protection Agency and the North Carolina Department of Environment, Health & Natural Resources. The slurry samples were taken from three different work sites. One site had twenty-year-old PCC pavement; one site had two-year-old PCC pavement; and one site had one-year-old PCC pavement.

This guide is from the National Concrete Pavement Technology Center regarding Partial Depth Repairs (PDR). Partial-depth repairs are defined as the removal and replacement of small areas of deteriorated (or spalled) concrete pavement. Partial-depth repairs slow or eliminate the spread of spalling distresses that tend to occur under repeated thermal stresses, freezing and thawing, and traffic loading.

The objective of this study was to monitor and evaluate the performance of experimental full-depth repairs (FDR) made with high early-strength (HES) materials placed under Strategic Highway Research Program (SHRP) project C-206, Optimization of Highway Concrete Technology. The C-206 full-depth repair experiment was conducted to demonstrate and validate the technologies that allow early opening of full-depth portland cement concrete (PCC) pavement repairs to traffic and to document the information needed to apply this technology.
