A STUDY OF A LABORATORY COMPACTION TEST USING A SWEDISH VIBRATORY APPARATUS

A STUDY OF A SWEDISH VIBRATORY COMPACTION APPARATUS FOR THE LABORATORY COMPACTION OF SOIL AND BASE MATERIALS IS DESCRIBED. THE RESULTS ARE COMPARED WITH THOSE OBTAINED WITH A B.S. LABORATORY COMPACTION TEST, USING A VIBRATING HAMMER, WHICH HAS BEEN DEVELOPED AT THE LABORATORY. THE MATERIALS USED IN THE STUDY WERE A HEAVY CLAY, A UNIFORMLY GRADED FINE SAND, A WELL-GRADED SAND AND A CRUSHED LIMESTONE. WITH ALL FOUR MATERIALS TESTED THE SWEDISH VIBRATORY COMPACTION APPARATUS PRODUCED DENSITIES WHICH WERE EITHER SIMILAR TO OR SOMEWHAT LOWER THAN THOSE OBTAINED USING THE B.S. VIBRATING HAMMER COMPACTION TEST. OPTIMUM MOISTURE CONTENTS WERE SIMILAR OR VERY SLIGHTLY HIGHER. THE DIFFERENCES IN MAXIMUM DRY DENSITY WITH SOME MATERIALS ARE SUCH THAT THE TWO TESTS CANNOT BE REGARDED AS ALTERNATIVES FOR SPECIFYING COMPACTION STANDARDS. THE PURPOSE IN DEVELOPING THE VIBRATING HAMMER COMPACTION TEST IN THE UNITED KINGDOM IS TO INDICATE THE RANGES OF MOISTURE CONTENT WITHIN WHICH GRANULAR MATERIALS SHOULD BE COMPACTED. FOR THIS PURPOSE THE SWEDISH APPARATUS IS AS EFFECTIVE AS THE NEW B.S. TEST. /AUTHOR/
