Generally, Asphalt mixture which is used surface or base of road acts a number of different deformation in agreement with all sorts of load. We authors gave these kinds of experiment in the past four years, that is to say, compressive test subjected to a linearly increasing strain ε_0t and repeated impulsive test. Materials such as steel and glass, often rearded as elastic at ordinary temperature, on close observations are found also to exhibit small amounts of viscous behavior. This can be observed as creep (increase of deformation at constant stress) or stress relaxation (decay of elastic stress at constant deformation), and these effects may be important under certain conditions of use. Then, it is generally said that the stability value of asphalt mixture is largely affected by the temperature and kinds of load. So, we must also deal with creep test of asphalt mixture. And we applied Bugers Body in connection with an analysis of creep test. These results of experiment are mentioned in this paper.
