APPLICATION OF STATISTICAL METHOD TO PAVEMENT MATERIALS

THE PRESENT METHOD OF REPORTING AND INTERPRETING BITUMINOUS MIX TEST DATA IS REVIEWED. PAST GRADATION TEST DATA ARE ANALYSED STATISTICALLY AND NEW SIEVE TOLERANCE LEVELS ARE SUGGESTED. A METHOD OF APPLYING REDUCED UNIT PRICES ACCORDING TO STATISTICAL TOLERANCES IS EXAMINED. DATA FROM A PAST JOB ARE PLOTTED ON QUALITY CONTROL CHARTS TO DEMONSTRATE BOTH THE ADVANTAGES OF QUALITY CONTROL CHART USE AND THE APPLICATION OF REDUCED UNIT PRICES PER LOT OF MATERIAL. A COMPUTER OUTPUT SHEET IS SHOWN WHICH WILL AID SUPERVISORS IN DETERMINING THE LEVEL OF QUALITY CONTROL BEING EFFECTED ON EACH PROJECT. /RATAOC/
