The report described the field testing of an in-service beam-slab highway bridge superstructure, consisting basically of five longitudinal prestressed concrete box beams, spread apart as in typical I-beam construction, cast-in-place slab, curb, and parapet sections, and end and midspan exterior diaphragms. A test vehicle, closely simulating an AASHO HS 20-44 design vehicle, was used. The principal objectives were to experimentally investigate the structural response of the superstructure (1) to the test vehicle traveling at constant speeds, in the range 2 - 60 mph, and (2) to an impact test in which the test vehicle passed over a ramp, two inches in height, at a speed of 10 mph, (3) to provide additional information on the lateral distribution of static vehicle loading.
