SHEAR STRENGTH AND ELASTIC PROPERTIES OF LIME-SOIL MIXTURES

THE SHEAR STRENGTH AND ELASTIC PROPERTIES OF SOIL-LIME MIXTURES AND THE EFFECTS OF CURING TIME AND SOIL TYPE ON THESE PROPERTIES WERE STUDIED USING FOUR TYPICAL ILLINOIS SOILS. REGRESSION EQUATIONS RELATING COHESION AND MODULUS OF ELASTICITY TO UNCONFINED COMPRESSIVE STRENGTH WERE DEVELOPED . AMONG THE AUTHORS CONCLUSIONS ARE' 1. LIME SUBSTANTIALLY INCREASES SHEAR STRENGTH DUE TO LARGE INCREASES IN COHESION AND SMALL INCREASES IN THE ANGLE OF INTERNAL FRICTION. 2. LIME INCREASES MODULUS OF ELASTICITY. 3. INCREASED CURING TIME INCREASES SHEAR STRENGTH AND MODULI OF ELASTICITY. 4. ULTIMATE FAILURE STRAIN FOR LIME-SOIL MIXTURES IS LESS THAN THAT FOR UNTREATED SOIL. ULTIMATE FAILURE STRAIN IS INDEPENDENT OF SOIL TYPE AND CURING TIME. 5. THE SHEAR STRENGTHS OF THE MIXTURES STUDIED WERE SUFFICIENT TO PREVENT SHEAR FAILURE OF THE LIME STABILIZED LAYER OF A TYPICAL FLEXIBLE PAVEMENT STRUCTURE. FLEXURAL STRENGTH WILL THUS BE THE CONTROLLING FACTOR IN RATIONAL DESIGN OF LIME-SOIL MIXTURES.
