MODERN CONCEPTS FOR DENSITY CONTROL PHASE 1: BITUMINOUS WEARING COURSES. PHASE 2: GRANULAR BASE COURSES

DENSITY DATA WERE OBTAINED ON BITUMINOUS WEARING COURSES AND ON GRANULAR BASE COURSES THAT WERE BEING CONSTRUCTED ON SEVERAL MINNESOTA TRUNK HIGHWAYS. DATA WERE COLLECTED AND ANALYZED FROM RANDOMLY SELECTED LOCATIONS ON FIVE BITUMINOUS SURFACING PROJECTS AND THREE GRAVEL BASE PROJECTS. A STATISTICAL ANALYSIS WAS ALSO PERFORMED ON RESULTS FROM OTHER BITUMINOUS AND GRANULAR BASE PROJECTS AND ON LABORATORY TEST RESULTS. VARIATION WAS DETERMINED FROM THESE DATA BY COMPUTING THE MEAN AND STANDARD DEVIATION TO REVEAL EXISTING VARIABILITY IN ACCEPTABLE CONSTRUCTION OF THESE 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. /AUTHOR/
