Abstract

Abstract

In order to effectively evaluate the high-temperature performance of asphalt mixture, rotary viscosity test, dynamic shear rheometer test and repeated creep test were conducted, viscosity, rut factor and creep model index were tested, the data of high-temperature creep test were fitted by using Burgers model, and the relativities between three rheological indices and the high-temperature performance were analyzed. Analysis result shows that rut factor doesn't fit to evaluate the high-temperature performance of modified asphalt mixture, the relative degree between creep model index and the dynamic stability degree of asphalt mixture is maximum, gets to 0.988 7, so creep model index can reflect the high-temperature performance of all kinds of asphalt mixtures accurately..
