NICKEL-COATED DOWEL PINS EXPOSED IN TIDAL ZONE HARBOR ISLAND , NORTH CAROLINA

RESULTS ARE REPORTED OF PULL-OUT TESTS OF PLAIN UNCOATED, HOT-ROLLED CARBON STEEL DOWELS AND HOT-ROLLED NICKEL-COATED STEEL DOWELS AFTER EXPOSURE IN THE TIDAL ZONE AT HARBOR ISLAND, N. C. HIGHWAY PERFORMANCE TESTS IN PROGRESS FOR 5 YEARS ARE DISCUSSED. FROM THESE TESTS ALL TYPES OF CORROSION RESISTANT DOWELS APPEAR TO BE FUNCTIONING PROPERLY AS NEARLY AS CAN BE DETERMINED FROM SEASONAL MEASUREMENTS OF JOINT OPENING AND CLOSING. THE TIDAL ZONE EXPOSURE AND ACCOMPANYING PULL-OUT DATA CONFIRM MITCHELLS CONCLUSION THAT A NICKEL-COATED DOWEL IS PROMISING. REFERENCES' THE PROBLEM OF LOAD TRANSFER DOWELS, R. G. MITCHELL, HRB BULL. 274, 57-69, 1960.
