The influence of contact type of Composite Bridge Deck pavement on stress in pavement interface

In order to study the stress distribution law of simply-supported bridge deck pavement the finite element software ANSYS is used to building the overall structure model of the composite bridge deck. The huge difference of materials of interface of concrete cushion layer and asphalt pavement layer in composite bridge deck affect the functional performance of the bridge deck pavement dramatically. Analysis shows that the mechanics characteristic of composite bridge deck pavement under different interlayer contact condition appears diversely.
