  • Abstract:
    The objective of this study was to monitor and evaluate the performance of experimental full-depth repairs 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. The experimental factors for the full-depth repair experiment included material type, strength at opening, and repair length. A total of 11 different HES concrete mixes with opening times ranging from 2 to 24 hours were evaluated at 2 field sites (U.S. I-20, Augusta, GA and State Route 2, Vermilion, OH).

    The scope of this study included 5-year monitoring of SHRP C-206 full-depth experiment sections, analyzing the data, and revising the guidelines for early opening of full-depth PCC pavement repairs as needed. The monitoring program consisted of annual visual distress surveys to monitor the development of cracking, faulting, and spalling. The annual surveys were conducted from the fall of 1994 through the fall of 1998. The results of this evaluation showed that full-depth repairs made with HES PCC can provide good long-term performance; however, adverse temperature conditions during installation can cause premature failures. Extremely high PCC temperatures during curing should also be avoided. The fatigue damage due to early opening is negligible, especially for repairs of 3.7 m or shorter. Within the range of strength evaluated under SHRP C-206, the strength at opening could not be correlated to performance. Based on the results of this evaluation, no changes are recommended to the opening criteria suggested in the SHRP C-206 manual of practice.
