Abstract:
Plastic limit (PL) and optimum moisture content (OMC) laboratory tests are essential for any earthwork construction since they play a significant role in any newly started construction site. But it takes an excessive amount of time to determine OMC. Many of the
index properties were found to be related to compaction parameters, optimum moisture content, and maximum dry density. The plasticity indices and the proportion of particles had the most significant connections, with the plastic limit having the highest degree of simple correlation. As a result, using the plastic limit of soil, it is necessary to determine these compaction properties. If compaction properties are correlated to plastic limit, it
may be easier to determine OMC. Finally, a simple equation has been generated to obtain the optimum moisture content (OMC) and the plastic limit (PL) of all the fine-grained soil. A useful equation and many graphical approaches have been used for quickly predicting compaction characteristics from index properties. The accuracy of these equations and graphical approaches has been assessed in this paper and determined to be adequate with most prediction results. This proposed correlation is going to be an easier method
for engineers in quickly assessing their suitability for compaction related purposes.
