Abstract: The damage characteristics of highway bridge expansion joints were analyzed systematically, and causes were analyzed from different aspects such as design, construction, management and maintenance. The optimization and improvement measures were put forward from two aspects, expansion joint structure and material application, and good results were obtained in guiding the engineering practice. It has practical significance and engineering application value.
