Title: Permanent Deformation Prediction of Steel Deck Pavements with Different Combinations
Abstract: For five types of pavement structures combined with gussasphalt and epoxy asphalt concrete,the repeated shear tests with constant height were conducted first to obtain the rheological characteristics of the two pavement materials.And then,the creep parameters of pavement materials were fitted with multiple nonlinear regression based on Bailey-Norton model.With the parameters of materials,a finite element model of orthotropic steel deck pavement was established to simulate the permanent deformation of pavement at 60 ℃.Finally,the simulation results were verified with the modified wheel track test.Research results show that of the two-layers pavement structures combined with different asphalt concretes,gussasphalt concrete has the highest deformation contribution rate,while epoxy asphalt concrete has the lowst.However,of the two-layers pavement structures combined with the same asphalt concrete,the rutting damage happens on the surface course.The research findings provide technique support for high-temperature performance design of structures and materials of steel deck pavement.
