LOAD RATING BRIDGES - A RATIONAL SYSTEM
Load rating is the process of computing the capacity of a bridge to carry heavy vehicle loads. This paper sets out a rational system for determining the capacity of a bridge using two standard traffic loads - one to represent uncontrolled "normal" traffic, the other to represent exceptional heavy loads (permit vehicles). The load ratings are the proportions of these standard loads that a bridge can accommodate with safety. The load ratings are only calculated once for the standard loads. They are then used for determining if a deficient bridge should be posted with a load restriction, or if a permit vehicle can cross a bridge with safety. This unified approach facilitates the selection of the optimum route for the movement of a heavy vehicle, and allows the load capacity of links in the network to be upgraded in a logical manner to meet strategic objectives.
