Abstract
A bridge paving device includes one or more reference receivers to locate the bridge paving device in three-dimensional space. A computer apparatus receives the location of the bridge paving device and associates the location with a bridge paving design profile. The computer apparatus independently actuates a system of hydraulic actuators of the bridge paving device to level and orient the bridge paving device regardless of the travel surface the linear movement elements are running on. Additional hydraulic actuators may adjust the shape of the bridge paving device over time as the bridge paving device travels a linear distance of the bridge to be paved. The shape adjustment alters a crown or inversion applied to the bridge such that run-off characteristics are more variable and controllable along the entire span of the bridge.
