APPLICATION OF STATISTICAL QUALITY CONTROL PROCEDURES TO THE PREPARATION OF SPECIFICATIONS

HISTORICAL DATA WERE COLLECTED AND ANALYZED FOR SEVERAL CONTINUOUSLY TESTED MATERIALS SUCH AS ASPHALTS MATERIALS, PORTLAND CEMENT, COARSE AGGREGATE AND LIMEROCK BASE. THE RESULTING STATISTICAL PARAMETERS WERE USED TO SHOW VARIATIONS ASSOCIATED WITH CERTAIN TESTS, THE DEGREE OF CONFORMANCE WITH EXISTING SPECIFICATIONS AND THE DEVELOPMENT OF ACCEPTANCE PLANS. METHODS OF OPTIMIZING SAMPLING FREQUENCIES AND TESTING PROCEDURES WERE STUDIED AND MODIFICATIONS TO EXISTING PRACTICES WERE RECOMMENDED TO IMPROVE THE COST-BENEFIT RELATIONSHIP. THE RECOMMENDED ACCEPTANCE PLANS INCLUDED SAMPLING AND TESTING FREQUENCIES PLUS PRICE ADJUSTMENT SCHEDULES. SPECIFIC AREAS OF ADDITIONAL RESEARCH WERE RECOMMENDED. /BPR/
