Abstract: During the period May through August 2012, researchers of the U.S. Army Engineer Research and Development Center (ERDC) in Vicksburg, MS conducted accelerated pavement testing using a C-17 load cart to evaluate the performance of a precast portland cement concrete (PCC) pavement repair system. The system was originally developed by the Air Force Research Laboratory (AFRL) in 2009 but was modified in a joint venture between AFRL and ERDC in 2011 and 2012 as Phase 1 of this project. Three PCC precast panel repairs were performed using the modified system. The precast repairs evaluated were a single-panel, a double-panel, and a quad-panel repair, which simulated repairing a quarter, a half, and a full pavement slab, respectively. Simulated C-17 traffic was applied to the repaired surfaces to determine if the precast panel repairs were suitable for withstanding aircraft traffic for emergency or contingency airfield operations. This report presents the results of accelerated pavement testing including the passes-to-failure, surface deterioration, load-transfer efficiency, deflections, and stress-strain measurements during trafficking. Results of this investigation will be used to further refine the design of the precast panel repair system. NOTE: This file is large. Allow your browser several minutes to download the file.
