PROCEDURES FOR USING STATISTICAL METHODS FOR PROCESS CONTROL AND ACCEPTANCE OF BITUMINOUS MIXTURES

THIS STUDY ON WAYS AND MEANS OF APPLICATION OF STATISTICAL METHODS FOR PROCESS CONTROL AND ACCEPTANCE OF HOT-MIX BITUMINOUS MIXTURES WAS PROMPTED BY THE FACT THAT THE SOUTH CAROLINA STATE HIGHWAY DEPARTMENT HAD PUT STRONG EMPHASIS ON STRICT COMPLIANCE WITH SPECIFICATION CONTROL WHILE REALIZING THAT VARIATIONS ARE INHERENT IN MATERIALS, CONTRUCTION PROCEDURES, SAMPLING AND TESTING. PHASE I DEVELOPED STATISTICAL QUALITY CONTROL PROCEDURES FOR PROCESS CONTROL AND ACCEPTABILITY FROM ACTUAL PROJECTS EMPLOYING HOT-MIX ASPHALTIC PAVING MATERIALS. PHASE II INVESTIGATED THE COMPLETED COMPONENTS TO VERIFY THE PROCEDURES. PHASE III PREPARED A TENTATIVE SYSTEM OF PROCESS CONTROL AND ACCEPTANCE OF MIXTURES AND TESTING OF FOUR PROJECTS AT DIFFERENT LOCATIONS. PHASE IV USED THE DATA AND EXPERIENCE GAINED IN THE PRECEDING PARTS OF THIS STUDY TO DEVELOP A SYSTEM FOR PROCESS CONTROL AND ACCEPTANCE OF ASPHALTIC MIXTURES AND A PROCEDURE FOR ADJUSTING THE UNIT PRICE FOR UNACCEPTABLE LOTS OF MATERIAL. MODEL SPECIFICATIONS, EMPLOYING STATISTICAL CONCEPTS WERE PRESENTED.
