Abstract:
LAB TEST PROCEDURES AND DATA OBTAINED ARE PRESENTED FOR AN EXAMINATION OF THE VOLUME AND MOISTURE CHANGES WHICH OCCUR IN SOILS SUBJECTED TO A READY SUPPLY OF WATER AND A PROLONGED PERIOD OF DRYING. TESTS WERE CONDUCTED AT VARYING DENSITIES AND MOISTURE CONTENTS. SHEAR STRENGTHS ARE GIVEN FOR SATURATED MOISTURE CONDITIONS AT VARIABLE DENSITIES. THE REPORT SHOULD BE USEFUL TO ENGINEERS IN THE CONSIDERATION OF SPECIFICATIONS LIMITING MOISTURE AND DENSITY FOR EMBANKMENT COMPACTION SINCE IT SHOWS HOW FINAL VOLUME CHANGE AND BEARING CAPACITY OF EMBANKMENT SOILS ARE AFFECTED BY MOISTURE AND DENSITY AT THE TIME OF CONSTRUCTION. FOR A GIVEN COMPACTED DENSITY THE VOLUME CHANGE OF SOIL ON SUBSEQUENT WETTING IS SHOWN TO VARY INVERSELY WITH ITS INITIAL MOISTURE CONTENT (ON DRYING IT VARIES DIRECTLY). THE BEARING CAPACITY VARIES DIRECTLY WITH COMPACTED DENSITY FOR A GIVEN INITIAL MOISTURE CONTENT. /AUTHOR/
