Draft Australian Bridge Design Code AS-5100 section 4: bearings and expansion joints: trends in rehabilitation of deck joints and design developments of modular joints

The Draft of Australian Standard AS-5100 released for public comment is the intended replacement for the current Austroads Bridge Design Code 1996. This paper will review the key changes in specification requirements of expansion joints between the current Austroads BDC and draft AS-5100. In further review of bridge deck expansion joints this paper will discuss recent trends in the approach to the rehabilitation of single element deck expansion joint systems with movement range up to 100mm. The paper will highlight the need for assessment by the specifying engineer of correct process control of the rehabilitation methodology. Larger movement multi seal element “modular” expansion joints have recently been the subject of significant review by road authorities with respect to their requirements to the design approach of the product. Such reviews have been driven by the in-service failure of some proprietary systems. This paper will summarise the principal areas addressed in current design of new generation modular expansion joints arising from these more demanding specifications.
