A CRITICAL REVIEW OF THE DENSITY TESTING PROGRAM IN WASHINGTON

IN RECENT YEARS, WASHINGTON HAS USED END PRODUCT SPECIFICATIONS FOR COMPACTION OF EMBANKMENTS AND HAS CARRIED OUT EXTENSIVE TRAINING PROGRAMS REGARDING CONTROL OF COMPACTION AND DENSITY TESTING. TO REVIEW THE ADEQUACY OF THE TESTING PROGRAM AND TO DETERMINE THE EFFECTIVENESS OF THE TRAINING PROGRAMS, A STUDY OF DENSITY REQUIREMENTS AND RESULTS WAS INITIATED IN 1963 AND CONTINUED IN 1964, REQUIRING THE REVIEW OF OVER 23,000 FIELD DENSITY TESTS. A COMPUTER PROGRAM BASED ON STATISTICAL REVIEW OF DATA WAS UTILIZED TO COMPUTE AND PLOT CURVES WHICH ASSISTED IN STUDYING AND EVALUATING THE TESTING RESULTS FOR EACH PROJECT AND DISTRICT. A UNIFORMITY INDEX WAS DEVELOPED AND USED AS A GUIDE FOR COMPARING TEST RESULTS AND DETERMINING WHAT PROGRESS HAD BEEN OBTAINED IN THE TESTING PROGRAM. THE IMPROVEMENT THROUGHOUT THE STATE IN DENSITY TESTING AND CONTROL AND SUMMARIZATION OF THE ADVANTAGES OF THE BIAS TESTING PROGRAM OVER OTHER PREPARED PROCEDURES ARE DESCRIBED. /AUTHOR/
