Abstract
The axle forces applied by a vehicle through its wheels are a critical part of the interaction between vehicles, pavements and
bridges. Therefore, the minimisation of these forces is important in order to promote long pavement life spans and ensure that
bridge loads are small. Moreover, as the road surface roughness affects the vehicle dynamic forces, the monitoring of
pavements for highways and bridges is an important task. This paper presents a novel algorithm to identify these dynamic
interaction forces which involves direct instrumentation of a vehicle with accelerometers. The ability of this approach to predict
the pavement roughness is also presented. Moving force identification theory is applied to a vehicle model in theoretical
simulations in order to obtain the interaction forces and pavement roughness from the measured accelerations. The method is
tested for a range of bridge spans in simulations and the influence of road roughness level on the accuracy of the results is
investigated. Finally, the challenge for the real-world problem is addressed in a laboratory experiment.
