STRENGTH-CONSISTENCY INDICES FOR A COHESIVE SOIL

A PROBLEM OF CONSIDERABLE IMPORTANCE IN MATERIALS CONTROL AND TESTING, AS WELL AS THE PRACTICAL ASPECTS OF MANY PHASES OF CONSTRUCTION, IS THAT OF RELATING OR ESTIMATING THE RESPONSE OF A COHESIVE SOIL AT A PARTICULAR CONSISTENCY OR STRENGTH, UNDER A PARTICULAR SET OF ENVIRONMENTAL CIRCUMSTANCES, FROM THE RESPONSE FOR THE SAME SET OF CIRCUMSTANCES BUT AT A DIFFERENT MOISTURE CONTENT OR CONSISTENCY OF THE SOIL. THIS DIFFICULTY IS DISCUSSED IN TERMS OF A STRENGTH-CONSISTENCY INDEX BASED ON THE UNCONFINED COMPRESSION STRENGTH OF A REMOLDED PLASTIC CLAY OBTAINED BY A CONSTANT RATE OF DEFORMATION TEST. STRENGTH AND CONSISTENCY CHARACTERISTICS OF VARIOUS SOIL SPECIMENS AT DIFFERENT MOISTURE CONTENTS ARE GIVEN. SPECIMENS ARE PREPARED BY VARIOUS TECHNIQUES, INCLUDING EXTRUSION AND COMPACTION PROCESSES. IN ADDITION, THE EFFECTS OF OVER- CONSOLIDATION AND DESICCATION ARE CONSIDERED. THE USEFULNESS OF SUCH AN INDEX IN MATERIALS CONTROL AND TESTING IS ILLUSTRATED FOR SOME ASPECTS OF CREEP AND VIBRATORY LOADING PHENOMENA. ANALYTIC EXPRESSIONS ARE GIVEN FOR THE RESPONSE. /AUTHOR/
