A CONCRETE BRIDGE DECK SURVEY BY THE SUR/FAX PHOTOGRAPHIC METHOD
AS PART OF A STUDY OF THE DETERIORATION OF CONCRETE BRIDGE DECKS, A CONDITION SURVEY OF 18 STRUCTURES WAS MADE WITH SUR/FAX PHOTOGRAPHIC EQUIPMENT, DEVELOPED AS A TOOL FOR CONDUCTING SURVEYS OF PAVEMENTS. THE PURPOSE OF THE STUDY WAS TO DETERMINE THE ABILITY OF THE PHOTOGRAPHIC EQUIPMENT TO DETECT TYPICAL DEFECTS IN CONCRETE BRIDGE DECKS. THE STRUCTURES SURVEYED, 15 OF WHICH WERE LESS THAN FIVE YEARS OLD, WERE SELECTED TO INCLUDE CRAZING, DISINTEGRATION, HAIR CHECKING, MAP CRACKING, PITTING, POPOUTS, SURFACE SCALING, AND TRANSVERSE STRUCTURAL CRACKS. THE RESULTS OF THE PHOTOGRAPHIC SURVEY WERE COMPARED WITH THOSE OF A DETAILED VISUAL SURVEY. THE GENERAL CONCLUSION DRAWN WAS THAT ADDITIONAL DEVELOPMENT WAS NEEDED IN THE SUR/ FAX METHOD TO MAKE IT PRACTICAL FOR GENERAL USE IN SURVEYS OF BRIDGE DECKS. /AUTHOR/
