STRUCTURAL ANALYSIS OF PAVEMENTS UNDER DYNAMIC LOADS
This paper presents a model for structural analysis of pavements under dynamic loads, using the Finite Element Method, which was developed having in mind its use in the dynamic analysis of FWD test results, and the analysis of the effect of dynamic loadings induced by heavy vehicle axles on pavements. The pavement is modelled as a system of horizontal layers of continuous, isotropic, homogenous and linear elastic materials, with constant thickness. The load is assumed to be uniformly distributed on a circular area of the pavement's surface. Its variation with time may be defined by any continuous function, namely a combination of sine and cosine functions. Layer materials are characterized by their elastic moduli, Poisson ratio, specific mass and damping ratio. An example is presented, in which the model is used to calculate deflections induced by FWD tests performed on a pavement from Lisbon airport, showing a good agreement between measured and calculated deflection time-history.
