STRESS-CORROSION SUSCEPTIBILITY OF HIGHWAY BRIDGE CONSTRUCTION STEELS. PHASE 1

A CATOLOG OF STEELS USED IN HIGHWAY BRIDGE CONSTRUCTION HAS BEEN DEVELOPED. A STATE-OF-THE-ART SURVEY ON THE STRESS- CORROSION SUSCEPTIBILITY OF THESE STEELS HAS BEEN CONDUCTED. THE TYPES AND CONCENTRATION OF CORROSIVES THAT CAN BE EX- PERIENCED IN THE HIGHWAY ENVIRONMENT HAVE BEEN ESTABLISHED. IT IS CONCLUDED THAT CARBON STEELS (A7,A9,A36, AND A373), WHICH HAVE BEEN USED PREDONINANTLY IN BRIDGE CONSTRUCTION, ARE NOT SUSCEPTIBLE TO STRESS-CORROSION CRACKING IN THE HIGHWAY ENVIRONMENT. INSUFFICIENT INFORMATION IS AVAILABLE TO ASSESS THE STRESS-CORROSION RESISTANCE OF HIGHER STRENGTH STEELS WITH THE REQUIRED LEVEL OF CONFIDENCE. FRACTURE MECHANICS TYPE TESTS ARE PROPOSED TO OBTAIN THIS INFORM- ATION. /FHWA/
