ATMOSPHERIC CORROSION TESTS OF UNPAINTED STEELS FOR USE IN CONSTRUCTION OF HIGHWAY BRIDGES
A 1967 PAPER ON ATMOSPHERIC CORROSION TESTS OF LOW-ALLOY STEELS AND THE APPLICABILITY OF THE TEST RESULTS TO HIGHWAY BRIDGES CONCLUDED THAT FURTHER TESTING AND RESEARCH WERE NECESSARY IN ORDER TO CLARIFY CERTAIN CONCEPTS. SINCE THEN, THE NEW JERSEY DEPARTMENT OF TRANSPORTATION AND THE BETHLEHEM STEEL CORPORATION HAVE JOINTLY UNDERTAKEN THE DEVELOPMENT AND IMPLEMENTATION OF CORROSION TESTS OF UNPAINTED STEELS. THIS PAPER IS A PRELIMINARY REPORT ON THE CORROSION TESTS AND INCLUDES NO DATA RESULTS, AND THEREFORE NO FORMAL CONCLUSIONS, AS YET. THESE TESTS, CONDUCTED IN THE INDUSTRIAL ATMOSPHERE OF NEWARK, NEW JERSEY, ARE INTENDED TO PROVIDE DATA THAT WILL AID IN DETERMINING THE EFFECT OF ROAD SALT SPRAY AND LOCAL CORROSION FACTORS, AS WELL AS IN ESTABLISHING TIME-CORROSION CURVES. RUST-STAINING OF ADJACENT MATERIALS (I.E., CONCRETE BRIDGE ABUTMENTS AND COLUMNS) IS ALSO ACCOUNTED FOR IN THE TEST PROGRAM. BECAUSE OF THE MANY DIFFICULTIES ENCOUNTERED IN THE PROCEDURE SUCH CONCEPTS AS STRESS CORROSION EFFECTS, CYCLIC LOAD ON CORROSION RATE, REDUCTION IN FATIGUE STRENGTH, AND LOSS OF TENSILE STRENGTH DUE TO CORROSION. DETAILS OF THE COMPLETE TEST PROGRAM IN PROGRESS ARE GIVEN. /AUTHOR/
