Abstract:
The principal cause of deterioration to the superstructure and substructure are the expansion joint systems. Bridge engineers and maintenance personnel have long advocated longer spans with fewer and maintenance-free expansion joints. With longer spans, expansion joints have become greater. In 1978, the New York State Department of Transportation invited manufacturers of six different types of modular expansion systems to install their devices on a new structure crossing the Hudson River at Troy, N.Y. This paper is an up-to-date condition survey of the performance conducted on a regular basis of the six different modular expansion joints.
