Findings from this study are of immediate assistance to the future FAA airport pavement research. In addition, a set of strain, thermally induced fatigue, and fracture parameters were used to derive ratios between the full-scale and laboratory tests, and a conceptual two-stage failure model was proposed. Once a crack initiated, it can penetrate a thin overlay in a very short period of time. It was observed that increasing overlay thickness significantly delayed the occurrence of reflection cracks, however not reduced the crack progression in the horizontal direction. This paper presents a comprehensive Federal Aviation Administration (FAA) study of full-scale and laboratory tests to evaluate the impact of overlay thickness on the initiation and propagation of reflection cracks. Although this option provides better thermal insulation to the concrete, which helps to reduce thermal movements, the performance is still somewhat empirical. In order to delay reflection cracks, a thicker overlay is sometimes applied than that required for structural purposes alone.
