Abstract
Asphalt mixture is a kind of simple thermal rheological material. The main mechanics behavior character of viscoelastic material is its time dependence, which lies in the existence of the interior timepiece or the characteristic time influenting by many factors. The free volume theory of material viscosity is usually used to study the characteristic time. Based on this theory, this paper deduced the time-temperature equivalent relation of Williams-Landel-Ferry (WLF) equation. Aging influences the viscosity as well. Through the creep test, this paper deduced the time-temperature, time-aging, temperature-aging equivalent equation. The equivalent principle also can be used in asphalt, modified asphalt and modified asphalt mixture.
