RATIONAL QUALITY ASSURANCE

THE PAPER DESCRIBES ASPECTS OF A RATIONAL SYSTEM FOR THE APPLICATION OF STATISTICAL QUALITY-CONTROL PROCEDURES IN HIGHWAY CONSTRUCTION. NORMS FOR THE JUDGMENT OF COMPLIANCE WITH A DOUBLE SPECIFICATION LIMIT ARE DEFINED IN TERMS OF PARAMETERS THAT WILL BE MEANINGFUL TO ROAD ENGINEERS. THESE NORMS ARE FURTHER QUALIFIED IN TERMS OF A FUNDAMENTAL RELATION OF THE APPLICABLE COEFFICIENT OF VARIATION AND THE NUMBER OF OBSERVATIONS REQUIRED FOR JUDGMENT PURPOSES. CORRESPONDING JUDGMENT NORMS ARE ALSO PRESENTED FOR USE WHEN A PRODUCT THAT FAILS TO COMPLY WITH SPECIFICATIONS WHEN FIRST SUBMITTED IS CONSEQUENTLY RESUBMITTED FOR ACCEPTANCE. INFORMATION IS ALSO PRESENTED THAT IS REQUIRED FOR THE PRACTICAL APPLICATION OF THE SCHEME. THIS INCLUDES COEFFICIENTS OF VARIATION THAT ARE REPRESENTATIVE OF CURRENT PRACTICE, DESIRED FREQUENCY OF SAMPLING, AND SUGGESTED LOT SIZES. FINALLY, THE APPLICATION OF THE METHOD IS ILLUSTRATED BY MEANS OF A PROPOSED SYSTEM LOGIC AND A PRACTICAL EXAMPLE BASED ON A DOUBLE SPECIFICATION LIMIT. /AUTHOR/
