RELATIONSHIP BETWEEN DENSITY AND STABILITY OF SUBGRADE SOILS

THIS PAPER DISCUSSES SOME OF THE LIMITATIONS OF THE CONCEPTS THAT THE STABILITY OF A COMPACTED SOIL INCREASES WITH AN INCREASE IN DENSITY AND THAT EVERY EFFORT SHOULD BE MADE TO ATTAIN THE HIGHEST PRACTICAL DENSITY IN FIELD COMPACTION. COMPREHENSIVE TEST DATA ON THE RELATIONSHIP BETWEEN DENSITY, STABILITY, WATER CONTENT, AND DEGREE OF SATURATION FOR TWO SOILS COMPACTED BY KNEADING ACTION ARE PRESENTED, TOGETHER WITH A DESCRIPTION OF THE TRIAXIAL INSTITUTE KNEADING COMPACTOR. IN THE TESTS, STABILITY IS MEASURED BY TRIAXIAL-COMPRESSION TESTS AND BY THE HVEEM STABILOMETER. THE SIGNIFICANCE OF THE CRITERION OF STABILITY ADOPTED WITH RESPECT TO THE RELATIONSHIP BETWEEN DENSITY AND STABILITY IS DISCUSSED. THE RELATIONSHIP BETWEEN THE ATTAINABLE STABILITIES AND THOSE DETERMINED BY SPECIFICATIONS BASED ON THE STANDARD PROCTOR AND MODIFIED AASHO COMPACTION TESTS IS DEMONSTRATED. DATA ARE ALSO PRESENTED ON THE DENSITY-VERSUS-STABILITY RELATIONSHIPS OF SOILS COMPACTED BY IMPACT AND STATIC PROCEDURES, AND THE EFFECT OF COMPACTION METHOD ON THE DENSITY-VERSUS-STABILITY RELATIONSHIP IS SHOWN. THE CONFLICTING CONCLUSIONS WHICH MAY BE REACHED ON THE BASIS OF TESTS ON SAMPLES PREPARED BY STATIC AND IMPACT METHODS OR BY STATIC AND KNEADING METHODS ARE INDICATED. /AUTHOR/
