QUALITY CONTROL OF ASPHALT PAVEMENT CONSTRUCTION

BECAUSE OF THE LIMITED INFORMATION AVAILABLE IN THE FIELD OF QUALITY CONTROL OF ASPHALT PAVEMENTS, AN INTENSIVE STUDY WAS MADE OF HUNDREDS OF TEST RESULTS FROM ACTUAL PAVING PROJECTS TO DETERMINE THE ACTUAL VARIATIONS WHICH DO OCCUR IN CONTROL TESTS. THE MEAN VALUES AND STANDARD DEVIATION VALUES WERE CALCULATED AND HISTOGRAMS SHOWING VARIATION WERE PLOTTED FOR ASPHALT PENETRATION, ASPHALT CONTENT, AGGREGATE GRADATION, SURFACE DENSITY, AIR VOIDS, MARSHALL STABILITY AND FLOW, ASPHALT SURFACE THICKNESS VARIATION. THE TEST RESULTS WERE COMPARED TO DESIGN VALUES AND SPECIFICATIONS. THE RESULTS INDICATE THE PERCENTAGE OF TEST RESULTS WHICH CAN BE EXPECTED TO FALL OUTSIDE OF SPECIFICATION LIMITS AND INDICATE THE USEFULNESS OF QUALITY CONTROL CHARTS IN INTERPRETING DATA. /CGRA/
