4.3 Compaction
The relationship between maximum dry density (MDD) and the used hydrated
lime content, in addition to the optimum moisture content (OMC)
relationship with the used hydrated lime content can be seen in Figure 6
and Figure 7 respectively. The best trend line for the MDD versus HL
plot is the linear correlation with a high coefficient of determination
R2 equal to 0.9792 as shown in Figure 6 and the
obtained corresponding linear equation as follows:
