A TEST FOR DETERMINING THE EFFECT OF WATER ON BITUMINOUS MIXTURES

THIS REPORT IS THE FIRST OF A SERIES OF REPORTS COVERING LABORATORY STUDIES ON THE FACTORS THAT AFFECT STRIPPING OF ASPHALT FILM FROM THE AGGREGATE PARTICLES IN A BITUMINOUS CONCRETE MIXTURE. IN THIS ORIGINAL WORK A PROCEDURE OF TEST WAS DEVELOPED WHICH IN LATTER WORK WAS CHANGED IN A NUMBER OF RESPECTS PARTICULARLY AS TO TEMPERATURE AND PERIOD OF IMMERSION. THE FACTORS STUDIED AND THE RESULTS OBTAINED SHOWED THE FOLLOWING: /1/ FILLER MATERIAL HAD A MAJOR EFFECT ON THE BEHAVIOR OF A BITUMINOUS PAVING MIXTURE. IT WAS INDICATED THAT SATISFACTORY RETENTION OF STABILITY MAY BE DEVELOPED IN MIXTURES CONTAINING HYDROPHILIC AGGREGATE, PROVIDED SUITABLE FILLER MATERIAL IS USED. /2/ THE TEST MADE POSSIBLE THE SELECTION OF THE FILLER MATERIAL BEST SUITED FOR A PARTICLES MIXTURE. /3/ IT MADE POSSIBLE THE DETECTION OF AGGREGATES STRUCTURALLY UNSOUND IN THE PRESENCE OF MOISTURE, AND /4/ THE TEST INDICATED THE USEFULNESS OF CERTAIN CHEMICAL ADDITIVES IN INCREASING THE RESISTANCE TO RESISTANCE TO STRIPPING OF THE BITUMINOUS FILMS FROM AGGREGATE PARTICLES IN THE PRESENCE OF WATER. /AUTHOR/
