The main aim of this study is to find out the static and modal response of the rigid pavement resting on different soil models subjected to aircraft loading. The FEM employed in this work is validated by a closed-form numerical problem, which is in great accord with previous research findings with a maximum divergence of 1.76 %. Furthermore, it has been investigated how the static response and cyclic frequency change as a result of variations in the thickness and span length of pavement, the modulus of the subgrade, different boundary conditions, and element discretization. Limited previous research has been performed in both static- and free vibration analysis of rigid pavement with 6 degrees of freedom (DOF). Also, very few researchers have carried out such a variety of parametric studies.
