INVESTIGATION INTO THE USES OF STATISTICAL PROCEDURES IN SPECIFICATION WRITING AND QUALITY CONTROL

THE APPLICATION OF SEVERAL METHODS AND TECHNIQUES OF STATISTICAL ANALYSIS TO ACCEPTED TESTS OF HIGHWAY CONSTRUCTION MATERIALS WAS DEMONSTRATED. THE RESULTS VARY RATHER WIDELY IN NUMERICAL VALUES. SOME TECHNIQUES COULD AND HAVE BEEN PUT IN ROUTINE USE AS A RESULT OF THE STUDY. OTHER TECHNIQUES ON CERTAIN MATERIALS YIELDED SUCH EXTREME VALUES THAT THE AUTHORS QUESTIONED THEM AS BEING IN ERROR OR THE METHOD BEING INAPPROPRIATE. THE AUTHORS CONCLUDED THAT THERE ARE AREAS WHERE STATISTICAL CONTROL TECHNIQUES ARE SUITABLE FOR USE AND OTHER AREAS EXIST WHERE THERE IS A NEED FOR CHANGE IN STATISTICAL CONCEPTS OR TEST METHODS, OR BOTH BEFORE THE S.R.C. PROCEEDS WITH WRITING AND ENFORCEMENT OF STATISTICALLY ORIENTED SPECIFICATIONS. /AUTHOR/
