MODERN CONCEPTS FOR DENSITY CONTROL; PHASE II: GRANULAR BASE COURSES

DURING 1969 AND 1970 DENSITY DATA WERE OBTAINED ON GRANULAR BASE COURSES THAT WERE BEING CONSTRUCTED ON SEVERAL MINNESOTA TRUNK HIGHWAYS. DATA WERE COLLECTED AND ANALYZED FROM RANDOMLY SELECTED LOCATIONS ON THREE GRAVEL BASE PROJECTS. A STATISTICAL ANALYSIS WAS ALSO PERFORMED ON RESULTS FROM NUMEROUS OTHER GRANULAR BASE PROJECTS. VARIATION WAS DETERMINED FROM THESE DATA BY COMPUTING THE MEAN AND STANDARD DEVIATION TO REVEAL EXISTING VARIABILITY IN ACCEPTABLE CONSTRUCTION OF GRANULAR BASE COURSES. THE RESULTS WERE USED TO EVALUATE PRESENT SPECIFICATIONS AND TO DEVELOP A NEW ACCEPTANCE SAMPLING PLAN. THE PLAN IS BASED ON STATISTICAL CONCEPTS THAT WILL DEFINE THE DEGREE OF ACCEPTABLE VARIATION UPON WHICH DECISIONS CAN BE MADE WITH AN ESTABLISHED DEGREE OF CONFIDENCE. PROPOSED STATISTICAL SPECIFICATIONS ARE PRESENTED. /NTIS/
