The function of expansion joints for highway bridges is to pass loads and to provide safety to the traffic over the gap between the bridge girder and the abutment or between two bridge girders. The rubber expansion joints follow much more easily to the horizontal movement and the rotation than the steel expansion joints. But the rubber expansion joints have the inferior abrasion resistance to the steel expansion joints.
In this paper, the change of requirements under the circumstances around the expansion joints is mentioned and the newly developed rubber expansion joint is introduced.
