Abstract

Abstract

In order to study the deformation properties of steel deck pavement under high temperature and their rutting predictions, two types of asphalt mixtures, mastic asphalt(MA) and stone mastic asphalt(SMA), were invited, and their high temperature performances were evaluated through repeated load triaxial test(RLTT). Through the multivariate linear regressive analysis of test result, the nonlinear parameters of asphalt mixtures were obtained, finite element software ABAQUS was applied to simulate the process of RLTT, and the calculalted deformation and measured deformation were compared. It is found that the natures of high temperature deformation developments for two mixtures, as well as the response manners to different load conditions, are completely different, SMA has an overwhelmingly excellent deformation resistance, and the calculation error of FEM is about 10%. The result indicates that it's reasonable to get the nonlinear parameters through multivariate linear regressive analysis from RLTT result, and it's qualified to apply these parameters to conduct the rutting prediction of asphalt pavement on steel bridge.
