Abstract	The slope change of an approach slab can induce a “bumping” effect to passing vehicles, magnify the vehicle impact on the bridge, and accelerate the deterioration of the bridge deck and other components. The allowable slope changes recommended in previous studies, which are usually based on the survey results of ride comfort only, are usually inconsistent. In this study, a three-dimensional vehicle-road-bridge interaction model is developed to study the interaction between passing vehicles and the road and bridge. By fully considering three important aspects, i.e., vehicle’s running safety, vehicle users’ comfort, and the impact on the bridge, an allowable slope change for approach slab is then proposed based on the recommended limits on the three indexes according to relevant codes. The proposed allowable slope change is considered more rational than previously recommended values and could be used as a reference for engineering practice.
