Abstract:

To analyze the stress state of steel orthotropic deck pavement and provide reference for the design of the overlay, the inner stress state and strain distribution of surfacing under the load of the deformation of the whole bridge structure and tyre load are analyzed by the finite element method of submodeling.Influence of surfacing modulus on the strain state of the overlay is analyzed for the purpose of the optimal design of the overlay structure.Analysis results show that the deformation of the whole bridge structure has no evident influence on the stress state of the overlay.The key factor of the overlay design is the transverse tensile strain in the overlay above the upper edge of web plate of rib.The stress state of the overlay is influenced evidently by the modulus of rigidity transform overlay.And the stress state of the overlay can be optimized and lowered by increasing the modulus and thickness of rigidity transform overlay.The fatigue test has been done to evaluate the fatigue performance and modulus of different deck pavement materials such as epoxy asphalt, SBS modified asphalt, rosphalt asphalt which can provide reference for deck pavement structure design.
