AB  - The researches have been done about composite pavements to date, indicating the suitable
performance of these types of pavements in comparison with flexible and rigid pavements. In this study, the
HMA/PCC structure of composite pavement is modeled with ABAQUS Finite Element Software in a 3D virtual
environment and the effect of two wide-body aircraft configurations with similar assumptions has been
analyzed in the model and the responses of the composite pavement have been evaluated. The results of this
study showed that the horizontal stresses under the concrete slab based on the thickness of pavement layers
is in about 22-26% of the stress under the asphalt layer, also the ratio of the maximum horizontal stress of the
concrete slab to asphalt layer for the B777-300R airplane is about 2.9 while this ratio of the A380-800 plane is
about 1.18 which is implied better configuration of A380-800 landing gear with respect to B777-300R and also
the module of elasticity of 4137 MPa could be selected as a suitable amount from the perspective of better
decreasing of stresses and deflections.
