CHARACTERISTICS OF COMPACTED EMBANKMENTS

THE PURPOSE OF THIS STUDY WAS TO PROVIDE DATA FOR ESTABLISHING STATISTICAL PARAMETERS FOR PERCENT COMPACTION OF COMPACTED EMBANKMENTS USING THE PRESENT AND LATEST TECHNIQUES IN TESTING METHODS AND THE STANDARDIZED SANDCONE, THE PARAMETERS ARE TO BE USED IN EVALUATING EXISTING REQUIREMENTS AND DEVELOPING NEW SPECIFICATIONS. THREE DIFFERENT EMBANKMENT PROJECTS WERE SELECTED FOR TESTING BY THREE DIFFERENT TESTS METHODS. THE RESULTS WERE ANALYZED TO DETERMINE THE STATISTICAL PARAMETERS NORMALLY USED TO EVALUATE QUALITY OF CONSTRUCTION. THE RESULTS INDICATED THAT THE THREE TESTS METHODS MAY BE USED INTERCHANGEABLY WITH COMPARABLE RESULTS. FACTORS CONCERNING SELECTION OF THE TESTING METHOD MUST DEPEND ON AVAILABILITY, ECONOMICS, ACCESSIBILITY OF WORK, SPEED OF TESTING AND VOLUME OF MATERIAL. SOME SKEWNESS OF FREQUENCY DISTRIBUTION CURVES WAS OBSERVED FOR THE PORTABLE NUCLEAR AND ROAD-LOGGER TEST DEVICES, WHILE THE SAND-CONE METHOD PRODUCED LESS SKEWED CURVES. VARIATION IN CONDITIONS CAUSED THE RESULTS OF ONE PROJECT TO BE DIFFICULT TO CORRELATE. HOWEVER, THE STANDARD DEVIATION OF THE THREE METHODS WAS SO SIMILAR THAT THE CHOICE OF DEVICE MIGHT DEPEND ON THE ECONOMY OF THE CONDITIONS. THIS STUDY INDICATES THAT NEW SPECIFICATIONS SHOULD BE WRITTEN TO INCLUDE USE OF NUCLEAR TESTING DEVICES FOR DETERMINATION OF SOIL EMBANKMENT DENSITY AND MOISTURE. A FULL SCALE PROJECT SHOULD BE DESIGNATED TO TEST THE PARAMETERS INDICATED IN THIS REPORT. /AUTHOR/
