Abstract



Compaction tests forms one of the important
aspects in geotechnical engineering practice. These tests are time consuming
and require large quantity of soil also. In this paper based on the results of
the compaction tests carried out for different soils of varying plasticity
characteristics at different compaction energies and on published data, it has
been brought that there is a good correlation between the optimum moisture
content and plastic limit for the . In addition to this one can predict the
modified compaction parameters just knowing the plastic limit of the soil.

For the present investigation, three
different soils from North Cyprus (Tuzla, Değirmenlik and Akdeniz) and a soil
from Turkey (highly plastic montmorillonitic clay) were chosen. These soils are
heavily in use for civil engineering activities like construction of pavements,
embankments and earth retaining structures. 

Compaction tests were carried out at three
different energy levels for the four soils described.. They are standard
Proctor test (SP), reduced modified Proctor (RMP) and modified Proctor (MP).
For the standard Proctor, the compaction energy works out to be 593.7 kJ/m3.
In the modified Proctor test, the compaction energy works out to be 2693.3 kJ/m3.
In the reduced modified Proctor test the procedure is same as modified Proctor
except the number of layers are three instead of five. The compaction energy
works out to be 1616 kJ/m3.

Based on the experimental results  obtained  
for  maximum dry density vs.
optimum moisture content for the four different soils with different compaction
energy levels it has been found 
that  irrespective of soil type
and compaction energy levels both the maximum dry density and optimum moisture
content are linearly related with a very high correlation coefficient of  R= 0.994.

Results obtained from laboratory tests as
well as from literature show that the correlation between maximum dry density
and OMC for different soils, compacted for two compaction energy levels is very
good.  

It is thus seen that one can predict OMC
knowing the plastic limit with reasonable accuracy.

Having obtained OMC one can get the maximum
dry density from equation(1) obtained in this study.

From experimental results it has been found
that   both OMC and maximum dry density
of Proctor’s test results and that of modified Proctor’s test results of
authors’ as well as data collected from literature correlate very well.

It is seen that the correlation is highly
satisfactory. Having obtained both OMC and maximum dry density for Proctor’s
energy level one can get the OMC and maximum dry density for modified Proctor
condition also.
