Fatigue life is one of the most important physical characteristic that is investigated by materials engineers and scientists.
Introduction Magnetorheological materials belong to a family of so-called smart materials whose rheological properties can be controlled rapidly and reversibly by the application of an external magnetic field.
Since their discovery in 1948 [1], magnetorheological materials have attracted intense interest.

Although nowadays activated carbon is the best well known and most efficient adsorbent, activated carbon remains an expensive material.
Therefore, it is necessary to product low cost and effective adsorption materials that can be applied to water pollution control.

Research on waste rubber asphalt mixture performance has become a currently research hot topic in the field of pavement materials [1-4].
Asphalt mixture as a kind of porous material, it absorbs a great lot of free water in the internal structure of asphalt mixture.
Rubber particle as a kind of lightweight and high elastic material takes the place of the part of aggregate of the asphalt mixture.
