Title: A STUDY OF TENACITY OF AGGREGATES IN SURFACE TREATMENTS
Accession Number: 00210280
Record Type: Component
Abstract: A STUDY WAS MADE TO DEVELOP A TENACITY TEST FOR MEASURING CHIP RETENTION IN SURFACE TREATMENT. A LABORATORY PROCEDURE IS DESCRIBED FOR FORMING A MONOLITHIC STRUCTURE ON THE SURFACE OF A SIMULATED ROADBED MADE UP ON A METAL PANEL. THE AGGREGATE CHIPS WERE ENCAPSULATED ON THE SURFACE SO THAT THE ENTIRE MASS COULD BE PULLED AWAY FROM THE ROADBED AND THE STRENGTH OF THE BOND BETWEEN THE AGGREGATE AND THE ROADBED DETERMINED. TO KEEP EXPERIMENTAL WORK TO A MINIMUM THE NUMBER OF VARIABLES STUDIED HAVE BEEN LIMITED TO AGGREGATE AND ASPHALT SPREAD QUANTITY, THE TYPE, SIZE AND SIZE DISTRIBUTION OF THE AGGREGATE, AND CONSISTENCY OF THE ASPHALT. RESULTS COVER A NUMBER OF THESE VARIABLES BUT ARE NOT A COMPLETE SURVEY OF ALL OF THEM. TO REDUCE VARIABILITY OF RESULTS, TEST PROCEDURES WERE STANDARDIZED CAREFULLY AND ENOUGH SAMPLES WERE TESTED SO THAT STATISTICAL METHODS COULD BE USED WITH CONFIDENCE. ADDITIONAL VARIABLES STUDIED BY STATISTICAL TECHNIQUES INCLUDE' /A/ EFFECT OF MOISTURE AND DUST IN THE AGGREGATE, /B/ DIFFERENT OPERATORS, AND /C/ THE EFFECT OF AGING BEFORE TESTING. /AUTHOR/
