Project description

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. When combined with other needed concrete pavement restoration (CPR) techniques, FDR can significantly increase pavement service life before structural overlay or reconstruction is required. FDR can also increase the life of a pavement to be overlaid by providing high joint load transfer efficiency (LTE) to restore stability and control reflection cracking severity
