BRIDGE DECK PERFORMANCE IN VIRGINIA

ONE OF THE MOST COMPREHENSIVE PROGRAMS FOR EVALUATION AND DEFINITION OF THE "DECK PROBLEMS" WAS THAT UNDERTAKEN COOPERATIVELY BY THE PORTLAND CEMENT ASSOCIATION, THE BUREAU OF PUBLIC ROADS AND EIGHT STATES DISTRIBUTED THROUGHOUT THE UNITED STATES. DETAILED STUDIES OF A FEW BRIDGES WERE MADE IN FOUR STATES AND THESE HAVE BEEN REPORTED (KANSAS 1965; MICHIGAN 1965; CALIFORNIA 1967; MISSOURI 1968). AS A PART OF THIS PROGRAM, SURVEYS WERE MADE ON FROM 100 TO 150 BRIDGES IN EACH OF EIGHT STATES INCLUDING VIRGINIA. THESE BRIDGES WERE RANDOMLY SELECTED TO REPRESENT ALL BRIDGES WITHIN A STATE. AS COMPARED WITH THOSE IN THE OTHER STATES, THE BRIDGES IN VIRGINIA SHOWED LESS CRACKING, SUBSTANTIALLY LESS SPALLING, AND SIGNIFICANTLY MORE SCALING. THE LOWER INCIDENCE OF CRACKING WAS ATTRIBUTED TO A GREATER PROPORTION OF SIMPLE SPANS IN THE VIRGINIA SAMPLE. IT WAS ALSO CONCLUDED THAT THE HIGHER FREQUENCY OF SCALING WAS DUE TO THE COMPARATIVELY LATE ADOPTION OF AIR ENTRAINMENT IN THE STATE. IT IS INTERESTING TO NOTE THAT THE OTHER SOUTHERN STATE, TEXAS, WHICH DID NOT USE AIR ENTRAINED CONCRETE, ALSO SHOWED A HIGH INCIDENCE OF SCALING, WHILE MINNESOTA, WITH A MUCH MORE SEVERE CLIMATE BUT ALSO A LONGER ULTILIZATION OF AIR ENTRAINMENT, SHOWED THE LOWEST INCIDENCE OF SCALING OF ANY OF THE STATES (EXCLUDING CALIFORNIA). /AUTHOR/
