The Federal Aviation Administration requires the use of stabilized bases for all pavements that will be required to support aircraft weighing 45,350 kg 100,000 lbs or more. A literature review was performed to determine the current state of the art in terms of understanding stabilization mechanisms, design procedures, and considerations. Field data were collected to provide a review of the performance of many pavements at high-volume airports that support heavy aircraft loads. Field data collected included structural data in the form of nondestructive testing NDT performed with a falling weight deflectometer, visual condition survey using the pavement condition index PCI procedure, and construction and maintenance history data. The NDT was evaluated to determine modulus values for the various pavement layers. The PCI data were compared to historic PCI data to determine trends in performance. The construction and maintenance history records were reviewed to determine rehabilitation efforts required to maintain the pavements at appropriate levels.
