Fracture Characterization and SEM Examination of NAPTF CC6 Concrete Mixes

The Federal Aviation Administration (FAA) rigid pavement design procedure utilizes the flexural strength to stress ratio to predict performance, based on regression models developed from full-scale experiments by the Corps of Engineers and FAA. Construction Cycle 6 (CC6) at the National Airport Pavement Test Facility (NAPTF) was constructed to further examine the effects of concrete strength on structural performance through full-scale accelerated testing. For CC6, FAA utilized concrete mixtures with three target flexural strengths. To complement the full-scale accelerated testing, both lab-cured and field-sawn beams were tested. Beam strength and fatigue tests were performed in the FAA testing lab. Fracture properties of the three design mixtures were determined at the Pennsylvania State University (PSU) laboratory following RILEM TC-187-SOC. Scanning Electron Microscopy was conducted to investigate the micro-structural differences between concrete samples to investigate apparent anomalies in other laboratory observations.
