| Abstract: | Through the survey to the expansion joint selection and installation in highway bridges in Jilin province,the damage phenomena on the expansion joint with different degrees are found,which will have serious impacts on the driving comfort and safety. After analysis the various damaged reasons in expansion joint have been found. And through the contrast to various types of expansion joint, the appropriate type of expansion joint is determined, and the construction plan is also put forward. Better effects have been obtained by the practice in Jilin province highways in recent years. The safety of the bridge in construction, the technique, and economic： rationality are assured. |
