A STUDY OF THE EFFECTS OF CONSTRUCTION PRACTICES ON BRIDGE DECK CONSTRUCTION

DURING THE PERIOD OF 1964 THROUGH 1966 SEVEN CONCRETE BRIDGE DECKS WERE OBSERVED UNDER CONSTRUCTION IN PENNSYLVANIA. SLUMPS AND AIR CONTENTS WERE RECORDED FOR EVERY TRUCKLOAD OF CONCRETE THAT WENT INTO THE DECKS. ALSO, THE PRECISE LOCATION OF PLACEMENT OF EVERY TRUCKLOAD OF CONCRETE WAS RECORDED, AND NOTE WAS TAKEN OF CONSTRUCTION PRACTICES THAT MIGHT ADVERSELY AFFECT THE PERFORMANCE OF CONCRETE. THE 7 BRIDGE DECKS WERE SUBSEQUENTLY INSPECTED DURING THE PERIOD OF 1967 THROUGH 1969, AND THE VARIOUS FORMS OF DETERIORATION WERE OBSERVED AND RECORDED. IN THIS WAY IT HAS BEEN POSSIBLE TO DETERMINE RATES OF DETERIORATION AND TO RELATE CONCRETE PROPERTIES AND CONSTRUCTION PRACTICES TO OBSERVED DETERIORATION. DETAILS OF BRIDGE CONSTRUCTION PERTINENT TO DURABILITY AND OBSERVATIONS MADE DURING SUBSEQUENT INSPECTIONS ARE COVERED FOR EACH DECK. THE CONSTRUCTION DIFFICULTIES THAT LEAD TO DURABILITY PROBLEMS, BASED ON THE OBSERVATIONS MADE IN THIS STUDY, ARE SUMMARIZED. /AUTHOR/
