Correlation of Maximum Laboratory Dry Density and Optimum Moisture Content of Soil with Soil Parameters

Abstract

The correlation of compaction properties of soil with various soil parameters are investigated in this study. These correlations were derived through graphically analysis. Soils samples were collected from ten cities of Punjab, Pakistan. The maximum dry density and optimum moisture content (O.M.C) are the compaction properties of soil, which is related to many of soil parameters that included Atterberg index (liquid limit (LL), plastic limit (PL), and plastic index (PI)), percentage of fines (silt, sand), coefficient of uniformity (Cu) and coefficient of curvature (Cc). The relationship of maximum dry density and percentage of fines (silt, sand), optimum moisture content and percentage of fines are the most important relations. These relationships provide a key role in the construction of highways. The effect on the maximum dry density of various kinds of soil, quantity of fines, and types of fines and distribution of the grain size become decided through a sensitivity evaluation that measured the effect of those parameters on acquired maximum dry density By measuring these correlations some unique behavioral developments have been analyzed and we conclude that properly-graded soils have better dry density than poorly graded when the soils have the equal fines content, further it became discovered that plastic fines have a tendency to boom the maximum dry density.
