Abstract: The urgent need to improve the understanding of truck damage to highway pavements has intensified interest in modelling the mechanics of the process. The process is being investigated by simulating trucks and combination vehicles to predict dynamic loads along the roadway in response to road roughness inputs. The dynamic loads are transformed into stresses imposed on the surface of pavement structural models from which the pavement responses and damage can be evaluated. This paper gives an overview of pitch-plane models for trucks and combination vehicles with emphasis on modelling suspension systems and the tyre-road interface. Parameters for characterising the truck population are discussed and presented.

Keywords: heavy vehicles; simulation; truck dimensions; truck inertial properties; tyres; dynamic loads; road damage; load prediction.
