QUALITY ASSURANCE IN HIGHWAY CONSTRUCTION

QUALITY ASSURANCE IS RELATED TO THE QUESTIONS WHAT TO DO, HOW TO ORDER IT, HOW TO ASSURE GETTING WHAT WAS ORDERED. SPECIFICATIONS WRITTEN TO ANSWER THE SECOND QUESTION HAVE HERETOFORE NOT PERMITTED THE THIRD TO BE ANSWERED QUANTITATIVELY. ENGINEERING JUDGMENT CAN USUALLY ASSURE A GOOD PRODUCT, BUT "SUSBTANTIAL COMPLIANCE" IS DIFFICULT TO DEFINE LEGALLY OR CONTRACTUALLY; FURTHERMORE, TRUE VARIATIONS IN MATERIALS OR CONSTRUCTION CAN REMAIN UNKNOWN WITHOUT PROPER SAMPLING AND INTERPRETATIVE METHODS. NEW TEST METHODS AVAILABLE FOR QUALITY CONTROL ARE SURVEYED. MEANS OF INCLUDING STATISTICAL QUALITY CONTROL IN SPECIFICATIONS AND TESTS, THE DIFFERENCES BETWEEN PRODUCTION AND ACCEPTANCE TESTING, AND FEDERAL AND STATE EFFORTS TO PROMOTE STATISTICAL CONCEPTS IN QUALITY CONTROL ARE DISCUSSED. THE IMPACT ON CONTRACTOR--STATE RELATIONS IS TREATED BRIEFLY. DETAILED TREATMENT IS GIVEN IN SEPARATE ARTICLES TO STATISTICAL QUALITY ASSURANCE FOR EMBANKMENTS AND BASE COURSES, PORTLAND CEMENT, BITUMINOUS CONSTRUCTION, AND HIGHWAY AGGREGATES.
