Abstract:
In geotechnical engineering, soil compaction is the practice in which a stress applied to a soil
causes densification as air is displaced from the pores between the soil grains.
This paper describes mathematical models and solution to predict the compaction properties
of soils (maximum dry density and optimum moisture content) from various physical
properties .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 sites. The maximum dry density and optimum moisture
content (O.M.C) are the compaction properties of soil, which relates many of soil parameters
that included Atterberg index (liquid limit (LL), plastic limit (PL), and plastic index (PI)),
percentage of fines (silt, clay).The relationship of maximum dry density and percentage of
fines (silt, clay), optimum moisture content and percentage of fines are the most important
relations A comparative study of the models reveals the one that can identify the best data
relationships.
From the mathematical models one can observe that there is a relatively good correlation
between OMC and LL, PL and NMC and similarly MDD with PL, LL,and ρ.
