INVESTIGATIVE TECHNIQUES USED OR CONTEMPLATED

CONCRETE DETERIORATION IN THE DECKS OF MISSOURI BRIDGES, WHICH HAS RAPIDLY DEVELOPED TO A DEGREE DEMANDING A PROGRAM OF EXTENSIVE MAINTENANCE AND RECONSTRUCTION, IMPELLED AN INVESTIGATION AIMED AT SOLVING THE PROBLEM. DURING THIS INVESTIGATION, CONSIDERABLE INFORMATION HAS BEEN GATHERED AND VARIOUS TECHNIQUES DEVISED AND EXECUTED OR CONTEMPLATED. THESE ARE PRESENTED FOR THE BENEFIT OF OTHERS CONCERNED WITH THE PROBLEM. INVESTIGATION OF THE SYSTEM OR SYSTEMS OF FACTORS PRODUCING EXTENSIVE DETERIORATION OF BRIDGE DECK CONCRETE REQUIRES (1) TERMINOLOGY TO INSURE ACCURATE IDENTIFICATION OF THE DIFFERENT TYPES OF DETERIORATION IN VARIOUS STAGES OF DEVELOPMENT, (2) METHODS AND PROCEDURES FOR MAKING EXPLORATORY, RECONNAISSANCE, OR SEMI-DETAILED OBSERVATIONS AND SURVEYS ON A LIMITED NUMBER OF DECKS SELECTED FOR SPECIAL STUDIES, (3) THE SELECTION, PROCUREMENT, EXAMINATION, AND TESTING OF CONCRETE SAMPLES FROM DECKS, AND (4) THE FORMULATION AND VERIFICATION OF HYPOTHESES SUGGESTED BY THE OBSERVATIONS AND DATA. EXPERIENCES WHILE FULFILLING THESE REQUIREMENTS ARE DESCRIBED AND DISCUSSED. HOWEVER, THE SCOPE OF THE PAPER AND THE PRESENT STATE OF PROGRESS OF THE INVESTIGATION DO NOT PERMIT THE PRESENTATION AND DISCUSSION OF AVAILABLE DATA. /AUTHOR/
