SURVEY TECHNIQUE AND IOWA EXPERIENCE

A SURVEY WAS CONDUCTED ON THE CONDITION OF BRIDGE DECKS ON INTERSTATE BRIDGES IN IOWA. SOME INSTANCES OF SCALING WERE FOUND. IN 49 OF THE 124 DECKS SOME LOCAL SURFACE SCALING APPEARED. PITTING AND POTHOLING WERE NOT SERIOUS PROBLEMS. STRUCTURAL CRACKS, WHICH ARE NEGATIVE MOMENT CRACKS, WERE FOUND TO OCCUR GENERALLY ON CONTINUOUS STEEL STRUCTURES AND FREQUENTLY ON PRESTRESSED CONCRETE STRUCTURES. PATTERN CRACKING DID NOT OCCUR FREQUENTLY, BUT A STUDY OF CONSTRUCTION TECHNIQUES COULD MINIMIZE IT. IT WAS CONCLUDED THAT FINISHING, CURING, AND INSPECTION TECHNIQUES SHOULD BE IMPROVED. BETTER CONSTRUCTION TECHNIQUES COULD MINIMIZE THE SCALING PROBLEM.
