Condition Survey of Continuous Bridge Decks
A field survey was conducted to evaluate the performances of Texas highway bridges with continuous decks, and to compare those performances with comparable bridges with noncontinuous decks. The most common defects found are: (1) transverse deck cracks; (2) longitudinal cracks in pan formed girder bridges; (3) spalls and cracks at ends of closure pours in prestressed concrete girders made continuous for live loads; (4) bent cap and beam end spalls in simple pan formed girder bridges; and, (5) damaged joint seals in simple spans. It is concluded that the service lives of continuous deck and simple deck bridges should be comparable if all are well maintained and if the steel is protected from deicing salt.
