Abstract
The lecture gives an overview of the earlier research related to vehicleroad interaction and of the present Directive. Methods are introduced for the measurement of the dynamic loads to the road surface, which are added to the static axle load. These include e.g. acceleration measurement on the vehicle, load measurement using piezo-electric transducers installed to the pavement, analysis in laboratory using the Hydropuls road simulator.
According to the results of the performed experiments, the dynamic load transferred to the road surface represents a significant part of the resultant peak loads, therefore the road damage caused by a vehicle can be reduced by the variation of the vehicle suspension parameters.
This solution seems to be more economical than further reinforcement of road structures. However, it can be put into practice only if a new Directive will be developed and introduced, which will stimulate the application of really road-friendly vehicle designs.
