Abstract:

The important parameters that influence the mechanical property of the paving layer on an orthotropic steel bridge deck are the paving layer thickness and modulus of the asphalt concrete surfacing. Three important indices that control the typical failures of the paving layer are the maximum tensile stress of paving layer, the maximum shear stress between the steel deck and the paving layer, and the maximum deflection on the paving surface. In this paper, the analytical model of paving systems on orthotropic steel bridge deck is established, and the finite element method is adopted to study the stress and strain of paving system. With the variation of asphalt concrete modulus in high or low temperature season, the influences of paving layer thickness on three control indices are researched. The results provide a theoretical basis for the determination of thickness of the paving layer on the steel bridge deck.
