- This paper will present selected problems connected with modelling of multi-layer pavements. Multi-layer pavement models, which utilize solutions such as the one of Boussinesq, Burmister, Kogan, Odemark and others, contain many simplifications, which bas a significant influence on the estimated real value of stress, strain, deflection as well as on the coefficient of pavement layers interaction. In the article based on the experiments carried out, we want to present our own layered-pavement models and solutions to them, which can be used mainly in the diagnostics of bearing capacity. The estimation of bearing capacity is conducted on the basis of full time data obtained with the FWD device. Moreover, the conclusions implicated by the above mentioned analysis are of big importance in design and operation process of road and airfield pavements. They pertain not only to the influence of modulus and thickness of particular layers but also to the way of pavement layers interaction, Poisson's coefficient, thermal characteristics and others.
