ABSTRACT
The stress state of steel deck asphalt pavement is different from general asphalt paving layer under the traffic load. For steel deck asphalt pavement, the stress mode is mainly in a complex threedimensional stress state. In order to thoroughly study the mechanical response characteristics of steel bridge deck pavement, it is necessary to study the three dimensional stress of pavement layer. In this paper, the three-dimensional viscoelastic constitutive theory of asphalt mixture is used to realize the three-dimensional mechanical response of steel deck asphalt pavement by applying the ABAQUS finite element software.
