Part A A CD test is performed on a sample of clean sand. The confining pressure is held constant throughout the test at 450 psf and the deviator stress at failure is 850 psf. What is the effective (drained) friction angle of the sand? Select best answer. a) 18 degrees b) 26 degrees c) 29 degrees d) 32 degrees e) 35 degrees No answer is even close f) Part B A modified Proctor compaction curve for a sandy fill has the following test data points. Dry Unit Weight (pcf) Water Content (%) 110 10 115 12 118 14 116 16 110 18 A sample of the compacted fill is collected from the field. It has a total unit weight of 118 pcf and is at a moisture content about 2% below the laboratory optimum. What is the relative compaction of the in-place fill? Part C For Part B, the entry for one data point is as follows: Weight of wet soil and dish: 857 g Weight of dry soil and dish: 760 g Weight of dish: 59 g Calculate the water content.
