GALVANIZED STEEL REINFORCED CONCRETE BRIDGE DECKS: PROGRESS REPORT

This project was initiated in 1969 as a cooperative study with the Federal Highway Administration. It includes construction of laboratory specimens and experimental bridge decks for evaluation of galvanized reinforcement as a deterrent to bridge deck deterioration. After undergoing six winters of heavy salt exposure, the following general conclusions can be made about the field specimens; all typical of deterioration have appeared in the specimens, serious deterioration is significantly less on the sections with galvanized rebar, at least 3 in. of concrete cover is recommended over the steel, and no significant effects could be noted where galvanized and ungalvanized rebar were placed in direct contact in the concrete. After four winters, all five experimental bridge decks with galvanized rebar are in excellent condition. The feasibility of using galvanized bars in Michigan bridge deck construction has been demonstrated by this experiment. Further reports will be issued on this project as more data are collected. /FHWA/
