BRIDGE DECK REHABILITATION: METHODS AND MATERIALS--PART I

The bridge deck deterioration processes of freeze-thaw scale, popout, and corrosion induced spalling are defined and the popular theories accounting for their mechanism are explained. Included is a basic discussion of corrosion. Oklahoma's method for surveying structures for deterioration is presented as well as the results of a statewide survey of structures using this method. Results of an attempt to correlate chloride concentration in concrete at the level of the upper rebar mat against half-cell potential is also included. /FHWA/
