Multi-Segment Pile-Supported Bridge Approach Slabs For Control Of Differential Settlement, Ahmed Bahumdain

Theses and Dissertations

The roughness of the transition between the bridge and the roadway is a well-known issue that affects roughly 25% of the bridges in the United States. As soil underneath the approach slab settles, deferential settlement develops between the bridge and the approaching roadway. This may negatively affect the ride quality for travelers and result in substantial long-term maintenance costs. Because of the differential settlement, bumps could develop at the ends of the bridge when abrupt changes in slope (exceeding 1/125) occurs.

This study was aimed at mitigating the formation of bumps at the ends of the bridge through a new …
