Abstract

Current pavement maintenance strategies are reliant on invasive measurements or visual inspection. Fibre- WIM sensors can improve this by measuring strain, which can be used to calculate axle loads. However, this process is not simple. Finite Element Modelling is used to study several circumstantial influences on the strain – axle load relationship. These factors are combined into a predicting function, which can be refined so that it can be used to calculate axle loads. This allows for more insight in pavement deterioration. Other than describing the results of the Finite Element Model, the implications for sustainable pavement maintenance are discussed.
