A general solving method for the plate-type model called M4-5n, relying on mixed finite elements is presented hereafter. In particular, we explain how embedded discontinuities in a multilayer pavement structure can be easily taken into account using the numerical approach developed... As an illustration, the approach developed is used to simulate the mechanical response of a pavement structure with cracks on which a full-scale accelerated fatigue test was performed.
