Refer to the 15-ft high embankment shown in Figure 3.8 (page 79). Embankments are generally constructed in several lifts or layers that are compacted according to geotechnical specifications. Each lift thickness is 3 ft and must have a dry unit weight of 120 Ib/ft3. It is known that the soil at the borrow pit has a moist unit weight of 110 Ib/ft3, moisture content of 23%, and Gs-2.66. Perform the following tasks. a. Determine the moist weight of borrow soil...
