The report describes the field testing of one of five beam-slab highway bridges included in an investigation of lateral distribution of vehicular loads in prestressed concrete spread box-girder bridges. Two cross-sections were gaged for the measurement of surface strains and deflections, and the data were collected through use of continuous recording equipment. The load vehicle was a 3-axle truck loaded to simulate the AASHO HS20-44 design vehicle. The structural response described was produced by crawl runs of the test vehicle, traveling across the bridge at 2-3 mph in each of five prescribed lanes. The principal study objectives were: (1) to develop information on lateral distribution of the vehicle loads to the girders, (2) to compare the distribution at two different cross-sections and (3) to compare the experimentally based distribution factors with values used in the design of the bridge.
