Long-Term Performance of Elastomeric Bridge Bearings
This report summarizes effects of long-term service on steel-laminated elastometric bearings placed on twin structures carrying the NY 400 Aurora Expressway over Conrail and NY 16 in Erie County. Expansion-joint bearings replaced as part of rehabilitation project on these bridges were recovered for evaluation. Generally, they were found to be in good condition. NYSDOT's current accelerated-test procedures were evaluated by comparing mean ratings of 1969 acceptance testing for these bearings after simulated aging, with results of the same tests in 1996 on as-received samples after their removal from these bridges. Included in this study is analysis of mean ratings of the 1969 acceptance-test results compared to similar tests repeated to judge effects of the years in service. Finally, the recovered bearings underwent acceptance testing for conformance with current specification tests. Bearings used in this project had problematic design, construction, and materials properties, but performed very well in service and were relatively insensitive to these deficiencies.
