Abstract : The report presents the results of a small-scale static load model study of aircraft runway pavements. It examines the effects of loading a rigid slab on an elastic foundation in the transitional area between the edge and interior o the slab. The model was a 0.130-in. thick Hydrostone slab supported by a 12 in. thick layer of natural rubber. The slab was instrumented with Type A-7, SR-4 electrical strain gages mounted along one centerline of the slab. The strain gages were positioned to indicate strains parallel and perpendicular to the edge, from the edge to the center of the slab. The behavior of the slab was observed by noting the change in strain effected by loads applied statically through circular footprints at various points along the instrumented centerline. The results are presented in non-dimensional terms.
