| Abstrait: |
The original design of the Wye Bridge and Beachley Viaduct accommodated thermal movements with an expansion joint – located at approximately the mid-point of the structure. This paper describes the development and execution of a scheme to address the material wear at the bearing surfaces and to improve the ride-quality over the joint by replacing the two rocker arm units which link the box girders either side of the expansion joint. |
