A STATISTICAL ANALYSIS OF EMBANKMENT COMPACTION

THIS STUDY STATISTICALLY EXAMINED THE DISTRIBUTION OF PERCENT RELATIVE COMPACTION OBTAINED WITH CURRENT COMPACTION CONTROL PROCEDURES USED IN CALIF. ON THREE EMBANKMENT PROJECTS WHERE THE SOILS VARIED FROM HOMOGENEOUS TO VARY HETEROGENEOUS MATERIAL. ANALYSIS OF PERCENT RELATIVE COMPACTION RESULTS REVEALED AVERAGE VALUES OF 92.9, 90.5 AND 93.5 PERCENT WITH STANDARD DEVIATIONS OF 2.4, 3.1 AND 5.5 PERCENT RESPECTIVELY. THE GREATEST DISPERSION IN RESULTS WAS FOUND WITH THE HETEROGENEOUS SOIL. THE DISTRIBUTION CURVES OF PERCENT RELATIVE COMPACTION AGREED GENERALLY WITH THOSE REPORTED BY THE U. S. BUREAU OF RECLAMATION AND THE AASHO ROAD TEST. FACTORS CONTRIBUTING TO THE DISPERSION OF PERCENT COMPACTION WERE FOUND TO BE TESTING PROCEDURE, THE SOIL, AND IN THE COMPACTION PROCESS. CURVES ARE PRESENTED WHICH PROVIDE A COMPARISON OF FIELD CONTROL TEST RESULTS AND RANDOMLY SAMPLED TEST RESULTS. A PARTIAL REVIEW OF PROBLEMS EXPECTED TO BE ENCOUNTERED IN THE DEVELOPMENT AND USE OF PURELY STATISTICAL SPECIFICATIONS IS PRESENTED. /BPR/
