STATISTICAL QUALITY CONTROL F-145/21/

THIS WAS CONDUCTED TYPE I SPECIAL /A/ ASPHALTIC CONCRETE SURFACE COURSE 3 INCHES THICK AND 24 FT. WIDE FOR A DISTANCE OF 7.4 MILES. A CONTINUOUS BATCH PLANT WAS EMPLOYED TO PREPARE THE CRUSHED LIMESTONE - SAND - ASPHALT MIXTURE. THE MIXTURE WAS PLACED WITH A BARBER-GREENE PAVER WITH AN AUTOMATIC LEVELER. THIS IS THE 3RD PROJECT OF THIS TYPE OF CONSTRUCTION AND THE DATA OF ALL THREE WILL BE CORRELATED FOR AVERAGES, SIGMAS AND VARIANCES OF GRADATION, ASPHALT CONTENT, DENSITY, THICKNESS AND STABILITY FROM RANDOMLY SELECTED OF SAMPLES AND MEASUREMENTS. THE STATISTICAL PARAMETERS DISCLOSE NON-UNIFORMITY OF MATERIAL SAMPLING OR TESTING PROCEDURES, THUS DESIGNATING AREAS NEEDING CORRECTIVE MEASURES TO PRODUCE UNIFORMITY OF FINAL PAVEMENT MATERIAL. NO CONCLUSIONS OR RECOMMENDATIONS ARE OFFERED AT THIS TIME, PERHAPS THE FINAL REPORT ON THE WHOLE STUDY WILL OFFER RECOMMENDATIONS. /BPR/
