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:
