The objective of this investigation was to design, construct, and evaluate two promising ALRS concepts for full-scale operations of the F-4 aircraft. After aircraft traffic was completed, test sections were trafficked to failure with loadcarts simulating maximum loaded F-4 and F-15 aircraft. Aircraft and pavement surface interaction were evaluated for a thin asphalt surfaced pavement and for unsurfaced stabilization soil pavement. Significant findings included 1 an asphalt surface course thickness of 2 inches over a conventionally designed pavement will support 150 passes of the F-4 aircraft, 2 a surface course is required for stabilized soil structures, particularly in areas subjected to jet blast for the prevention of foreign object damage to engines, 3 deflection from the falling weight deflectometer can be used with a layered elastic model to predict performance of the pavement structures, and 4 the CBR design procedure should not be modified for the design of ALRS pavements.
