The effects of simulated traffic induced vibrations on concrete-steel bond strength and concrete compressive strength in full-depth bridge deck repairs are studied. The effects of concrete slump, bar size, and cover are also considered. The vibrations match values obtained from field measurements; vibration amplitude (including that obtained for heavy vehicles) and frequency are duplicated in the laboratory. 1-1/2 in. and 3 in. top covers, #5 and #8 deformed reinforcing bars, and concrete slump ranging from 1-1/2 in. to 7-3/4 in. are used. Based on the experimental work, traffic induced vibrations appear to have no detrimental effect on either bond strength or compressive strength in bridge deck repairs, if low slump concrete is used. As slump is increased above about 4 in., however, both bond strength and compressive strength drop in comparison with nonvibrated concrete.
