EXPERIMENTAL CONCRETE PAVEMENT CONTAINING FLY-ASH ADMIXTURES

IN 1963 THE DEPARTMENT INITIATED AN EXPERIMENTAL PROJECT IN WHICH FLY ASH WAS USED AS A PARTIAL CEMENT REPLACEMENT IN A PAVING CONCRETE. A PERFORMANCE SURVEY CONDUCTED IN 1966 WAS INCONCLUSIVE, AND AN ADDITIONAL EXPERIMENTAL PROJECT WAS RUN UTILIZING A CONTROL SECTION AND ONE CONTAINING FIVE BAGS OF PORTLAND CEMENT AND 94 POUNDS OF FLY ASH PER CUBIC YARD. IT IS CONCLUDED THAT FLY ASH MAY BE USED AS A PARTIAL CEMENT REPLACEMENT. NO SAVINGS IN COSTS WERE REALIZED, BUT MIGHT BE WERE FLY ASH CONCRETE USED AS AN ALTERNATE TO CONVENTIONAL PORTLAND CEMENT CONCRETE. THE EXPERIMENTAL SECTION PERFORMANCE WAS NOT AS GOOD AS THAT OF THE CONTROL SECTION, BUT VARIATIONS WERE INSIGNIFICANT.
