STABILIZATION OF PLASTIC SUBGRADE SOILS WITH HYDRATED LIME AND PORTLAND CEMENT

A STUDY WAS MADE OF THE DESIGN, CONSTRUCTION AND EVALUATION OF TWO EXPERIMENTAL PROJECTS FEATURING LIME, PORTLAND CEMENT AND A COMBINATION OF LIME AND PORTLAND CEMENT STABILIZATION OF PLASTIC SUBGRADE SOILS. MIXING OF SOIL-STABILIZERS WAS ACCOMPLISHED USING DISCS, SCARIFIERS, ROTARY-TILLERS AND MOTOR PATROL BLADES. LIME-CEMENT COMBINATION SECTIONS WERE CONSTRUCTED BY FIRST MIXING LIME, LOOSE CURING FOR 24 TO 48 HOURS, AND THEN ADDING CEMENT, AND MIXING AND COMPACTING. EFFECTIVENESS OF TREATMENT WAS EVALUATED BY MEASURING THE UNCONFINED COMPRESSIVE STRENGTH OF CORES, BENKELMAN BEAM DEFLECTION MEASUREMENTS, MEASUREMENT OF PATCHING AND VISUAL OBSERVATIONS. THE AUTHORS CONCLUDED THAT HYDRATED LIME WAS MORE SUITABLE THAN PORTLAND CEMENT ALONE OR CEMENT-LIME COMBINATIONS FOR TREATING GLACIAL CLAY SOILS AND THAT IN GENERAL ALL THREE TYPES OF SUBGRADE TREATMENT WERE SATISFACTORY. /BPR/
