2. Moisture density curves for each test showing the maximum density and the optimum moisture<br />
content and ZAV curves plotted on two separate graphs; show only the three highest moisture<br />
content values for the zero air voids curve.<br />
3. On a separate graph plot both the <strong>Modified</strong> and <strong>Standard</strong> curves and a zero air voids curve.<br />
4. In the conclusions compare the maximum densities and the optimum moisture contents obtained<br />
in the two tests. Calculate the value of the ratio of the maximum dry densities:<br />
<strong>Standard</strong> ρ<br />
<strong>Modified</strong> ρ<br />
d max<br />
d max<br />
5. Compare the shapes of the moisture density curves in terms of whether: a) the left hand (wet)<br />
sides of the standard and modified curves parallel, b) the right hand (dry) sides are parallel to<br />
each other and c) the left hand (wet) sides are parallel to the zero air voids curve?<br />
