THE CONTROL OF HEAVY VEHICLE LOADING ON BRIDGES

Legal load restrictions on individual axles and groups of axles are discussed in relation to bridge structures. A comparison is made of the different types of axle spacing/mass schedules used to restrict group axle loads. Structural implications are outlined, and a theoretical method for comparing schedules is presented. A systematic procedure is described which determines the most adverse effects on bridge structures arising from the enforcement of a given set of legal restrictions on a number of trucks of specified geometry. The theoretical considerations behind the axle spacing/mass schedule proposed by the NAASRA economics of road vehicle limits study are discussed. Results obtained by use of a computer program for a number of studies on the proposed load limits and possible exemptions are presented. The paper concludes with a summary of the main points and the conclusions reached in deriving a new axle spacing/mass schedule for the Australian situation. /Author/TRRL/
