PADS EASE TRACK TRANSITIONS

For safety reasons, when crossing towns, railroad tracks are often elevated over streets, using short open-deck bridges. Since these bridges are much stiffer than the adjoining tracks, they generally cause an increase of the vertical load fluctuations in the vicinity of bridge abutments. This paper reports on a research program to develop and implement matched pad technology. As part of the effort, matched pads were designed, produced, and installed on a number of open deck bridges. The results obtained to date clearly show that the use of matched pads in conjunction with ballast packing near the abutments is an effective and economical way for greatly reducing, and possibly eliminating, the effect of track transitions and the associated maintenance costs at short bridges.
