Data points from a std moisture density test on a fine grained soil are given in the following table:

Water Total

Content Density

(%) (pcf) _______

20.0 99.6

23.1 105.9

25.6 111.2

28.5 115.1

31.3 113.4

34.0 111.5

a) Reduce the data and plot the water content versus dry density curve. Clearly indicate values for optimum water content and maximum dry density from this test.

b) Compacted one cylinder of the soil describes above problem 1 to compare the new results with shown above. The data obtained included a water content of 32.5% and a total density of 121.9 pcf. Comment on these new findings.

c) From above problem 1 assume that a field density test on a fill lift indicates a water content and a dry density of 23.2% and 88.6 pcf, respectively. Would specifications calling for minimum relative compaction of 96% of Std maximum dry density and water content 62% of optimum be satisfied.
