• Abstract:
  Bridge approaches provide smooth and safe transition of vehicles from highway pavements to bridge ; structures. However, settlement of the bridge approach slab relative to bridge decks usually creates a ; bump in the roadway. The bump causes inconvenience to passengers and increases the cost of ; maintenance and repairing of the distressed approach slabs. Typically, the Texas Department of ; Transportation (TxDOT) spends millions of dollars annually to mitigate the bump problem across the ; state. The present research aims to better understand the mechanisms that cause the bump problem, to ; review currently used methods to mitigate this problem around the world, and to develop the methods ; that are appropriate for researching them in real field conditions. As a part of this research, a synthesis ; was prepared by conducting a comprehensive literature review of the past research on the subject and ; also by conducting a survey with all 25 districts to understand the local conditions that contribute to the ; bump problem in the bridges. The literature review also identified several technologies that were used ; to mitigate the problem. All these details along with district wide surveys are covered in this synthesis ; report.
