For the data in Fig. 5.1:

(a) Estimate the maximum dry density and optimum water content for both the standard curve and the modified Proctor curve.

(b) What is the placement water content range for 90% relative compaction for the modified Proctor curve and 95% relative compaction for the standard Proctor curve?

(c) For both curves, estimate the maximum placement water content for the minimum compactive effort to achieve the percent relative compaction in part (b).?
