Water Intrusion In Base/Subgrade Materials At Bridge Ends, Priyantha Jayawickrama, Phil Nash, Michael Leaverton, Debakanta Mishra

Debakanta Mishra

Departments of transportation spend considerable time and money repairing pavement failures that occur in the base or subgrade materials near bridge ends. Investigation of these failures often reveal saturated base/subgrade materials. The objectives of this research were to determine all possible sources for water intrusion, develop methods to recognize in-the-field causes of water collection at bridge approaches, and to develop new repair methods that can be economically implemented in the field to minimize water intrusion or remove water from soils.

Research focused on existing bridge approaches, concentrated on maintenance techniques to prevent water intrusion at bridge ends, and included an …
