A NEW METHOD OF ASSESSING THE LIME REQUIREMENT FOR THE STABILIZATION OF SOILS FOR THE CONSTRUCTION OF ROAD BASES

LABORATORY INVESTIGATIONS WERE CONDUCTED TO FIND A SIMPLE METHOD OF ASSESSING THE LIME REQUIREMENT FOR SOIL STABILIZATION. IN WORKING OUT A NEW METHOD, ADVANTAGE WAS TAKEN OF THE PHYSICO-CHEMICAL CHANGES PRODUCED IN A SOIL DURING LIME-SOIL REACTION, RESULTING IN THE AGGREATION OF SOIL PARTICLES, IN A MANNER SIMILAR TO THE EFFECT OF CEMENT ON SOILS. IN AN EARLIER STUDY WITH SOIL-CEMENT, IT WAS SHOWN THAT CEMENT REQUIREMENT FOR A STABLE MIX COULD BE DETERMINED FROM THE VOLUMETRIC CHANGES PRODUCED IN THE CEMENT-SOIL SEDIMENTS PREPARED IN ABUNDANCE OF WATER. IN A SIMILAR MANNER, IT WAS OBSERVED THAT LIME-SOIL SUSPENSION WHEN SHAKEN IN PROFUSE QUANTITY OF WATER PRODUCED APPRECIABLE VOLUMETRIC CHANGES, WHICH COULD BE CONSIDERED AS THE CRITERIA FOR ASSESSING THE LIME REQUIREMENT FOR THE STABILIZATION OF SOILS. THIS WAS CONFIRMED BY SUBSEQUENT EXPERIMENTS CARRIED OUT WITH DIFFERENT SOILS USING INCREASING CONCENTRATIONS OF LIME. THE RESULTS OF LABORATORY INVESTIGATIONS ARE DISCUSSED IN THE PAPER.
