FIELD EXPERIMENT WITH STATISTICAL METHODS

FIELD AND OPERATIONS PERSONNEL WORKED WITH STATISTICAL PROCEDURES WHICH EMPHASISED THE IMPLEMENTATION OF RESEARCH RATHER THAN THE RESEARCH STUDY ITSELF. A RANDOM SAMPLING PROGRAM WAS INITIATED ON 41 MAINTENANCE SCHEDULES DURING 1967. ALTHOUGH THESE RESURFACINGS WERE INDIVIDUALLY SMALL, THEY PROVIDED CONVENIENT TESTING AREAS. THE RANDOM SAMPLING WAS PRACTICAL, INFORMATION ON VARIABILITY WAS REASONABLE AND THE STANDARD DEVIATIONS WERE - ASPHALT CONTENT CANNOT BE EXPECTED TO BE LESS THAN 0.25 PERCENT, COARSE AGGREGATE GRADATION COULD NOT BE EXPECTED TO BE LESS THAN 3.0 PERCENT AND FINE AGGREGATE NOT LESS THAN 2.0 PERCENT. /BPR/
