INVESTIGATION INTO THE GRADATION VARIABILITY OF AGGREGATES USED IN BASES

THIS PROJECT DETERMINED CHANGES IN GRADATION THAT RESULT IN HANDLING BASE COURSE MATERIALS FROM THE STOCKPILE THROUGH THE PUG MILL AND TO THE JOB SITE. VARIATION BETWEEN SEVERAL SAMPLING POINTS WAS DETERMINED. THE RESULTS INDICATE THAT, FOR THE PARTICULAR CONSTRUCTION JOB STUDIED, SAMPLING FROM THE BELT COULD BE USED AS AN INDICATION OF THE FINAL COMPACTED SAMPLES ON THE ROAD FOR THE UPPER SIEVE RANGES. HOWEVER, IN THE LOWER SIEVE SIZES, VARIATION WAS NOTED FROM THE BELT SAMPLES TO THE JOB SITE SAMPLES.
