Water Intrusion in Base/Subgrade Materials at Bridge Ends

differential settlement

Departments of Transportation spend considerable time and money repairing pavement failures in the base or subgrade material near bridge ends. Investigation of these failures often reveal saturate materials. This project aimed to determine all possible sources of water intrusion, develop methods to recognize in-the-field causes of water collection at bridge approaches, and to develop new repair methods that could be economically implemented to minimize water intrusion and remove water from soils.  Researchers surveyed each of the 25 TxDOT districts to gather observations about major factors contributing to the problem of water intrusion and settlement at bridge ends. Four districts were visited for field invesigations of specific bridges, and one bridge was selected for thorough field testing to determine sources of water intrusion for a recurring seepage problem.
