Correlation of compaction characteristics of natural soils with modified plastic limit

Compaction characteristics of soils being very important from field application point of view, any attempt to develop correlation equation to predict the same should be rational and universally applicable. It has been reported in the literature that the plastic limit of soils bear a good correlation with their compaction characteristics. In this study, attempts have been made to use modified plastic limit to account for the proportion of fraction less than 425 μm as a parameter to correlate with the compaction characteristics of natural soils. The proposed correlation between the compaction characteristics of natural soils with their modified plastic are going to be handy tool for construction engineers in quickly assessing their suitability for compaction related purposes.
