THE EFFECT OF PRETREATMENT MOISTURE CONTENT ON THE PROPERTIES OF CEMENT AND LIME STABILIZED CLAY SOILS

PRETREATMENT MOISTURE CONTENT (PTMC) HAS BEEN USED TO DESCRIBE THE SOIL MOISTURE CONTENT AT THE COMMENCEMENT OF THE STABILIZATION PROCESS, PRIOR TO THE ADDITION OF THE ADDITIVE AND PRIOR TO ANY MOISTURE ADJUSTMENT TO BRING THE SOIL TO THE COMPACTION MOISTURE CONTENT. FOR EXAMPLE, IN A CONSTRUCTION PROCESS, THE PTMC WOULD BE THE MOISTURE CONTENT AT WHICH THE SOIL IS PULVERIZED AND THE MOISTURE CONTENT AT WHICH THE ADDITIVE IS APPLIED. THE PTMC GREATLY AFFECTS PULVERIZATION AND HENCE THE GRADING OF THE SOIL- ADDITIVE-WATER MIX AND THIS, IN TURN, AFFECTS THE COMPACTED SOIL DENSITIES. THE PTMC CAN BE EASILY CONTROLLED IN THE LABORATORY. ITS MAJOR INITIAL EFFECT IS ON THE GRADING OF THE SOIL-ADDITIVE-WATER MIX, PRODUCING VARIATIONS IN COMPACTED DENSITY AND IN THE MECHANICAL PROPERTIES OF THE SOIL. THE LABORATORY PTMC SHOULD MATCH THE EXPECTED FIELD PTMC. A LABORATORY INVESTIGATON OF THE EFFECTS OF PTMC ON THE PROPERTIES OF TWO STABILIZED CLAY SOILS IS REPORTED. /TRRL/
