DEVELOPMENT AND TRIAL USE OF ACCEPTANCE SAMPLING PLANS FOR ASPHALT CONSTRUCTION /ABRIDGMENT/

THE RESEARCH ON VARIABILITY IN ASPHALT CONSTRUCTION IN NORTH DAKOTA BROUGHT TO LIGHT MANY CHARACTERISTICS OF CURRENT ACCEPTABLE ASPHALT CONSTRUCTION. THEY ARE (1) SINGLE TEST RESULTS EXHIBITED A LARGE VARIABILITY CAUSING MANY OF THE MEASUREMENTS TO BE OUTSIDE THE SPECIFICATIONS; (AVERAGE TEST RESULTS ARE RECOMMENDED); (2) THE CURRENT GRADATION BAND WAS ONLY PARTIALLY EFFECTIVE IN CONTROLLING AGGREGATE GRADATION; (TARGET VALUES SHOULD BE CHOSEN EITHER AT THE CENTER OF THE BAND OR IN 2 OR 3 STANDARD DEVIATIONS FROM THE CURRENT SEPECIFICATION LIMITS; AND (3) PAYMENTS TO THE CONTRACTOR WERE INDEPENDENT OF THE QUALITY OF HIS WORK; (SPECIFICATIONS SHOULD REQUIRE THE CONTRACTOR TO BEAR A GREATER RESPONSIBILITY FOR THE QUALITY OF HIS WORK, SUBSTANDARD WORK WOULD NOT BE PERMITTED OR THE PRICE COULD BE ADJUSTED).
