Abstract
This paper presents the influence of lime on the compaction behaviour of soils. A series of experiments have been carried out on six different soils having a wide range of plasticity, mixed with varied percentage of lime. Test results indicate that the maximum dry density reduces to about 3% of lime beyond which it continues to increase with increase in lime content. Correspondingly, the optimum moisture content was found to increase to 3% of lime beyond which it continued to decrease with further increase in lime content. It was observed that the compaction characteristics of lime-treated soils correlate better with the plastic limit than with the liquid and shrinkage limits. The correlations developed will be of use in efficient design and quality control of large-scale compactions in the field.
