UNIFORMITY OF BINDER COURSE MIXES PRIOR TO AUTOMATED PRODUCTION (AN ADDENDUM TO RR 66-3)

HOT BIN SAMPLE DATA, PROCURED IN 1961, FROM 18 NON-AUTOMATIC ASPHALT PLANTS WAS STATISTICALLY ANALYZED TO PROVIDE A BASIS OF COMPARISON WITH 1968 DATA OBTAINED FROM AUTOMATED PLANTS. THE 254 SAMPLE SETS FROM THE 1961 DATA WERE INVESTIGATED FOR THE PRIMARY SIZE IN EACH BIN, EXCEPT THE FINES BIN, AND FOR THE FINAL SAMPLE. THE W-STATISTIC WAS USED TO CHECK FOR DISTRIBUTIONAL FORM AND RUN TESTS WERE APPLIED TO THE PRIMARY SIZE AGGREGATE IN EACH BIN TO CHECK FOR DRIFTING OF THE PROCESS MEAN. THE W STATISTIC SHOWED DISTRIBUTIONAL FORM OF DATA CAN BE APPROXIMATED BY THE NORMAL DISTRIBUTION. DRIFTING OCCURRED IN AT LEAST 1 BIN IN 50 PERCENT OF THE PLANTS. HIGH PRIMARY SIZE VALUES IN THE HOT BINS ARE ASSOCIATED WITH MORE UNIFORM PRODUCTION. /BPR/
