Refer to Figure 2. Embankments are generally constructed in several layers that are compacted according to geotechnical specifications.layers that are compacted according to geotechnical specifications. The thickness of eachof each layer is 3ft and should have a dry unit weight of 118 lb/ft3 .. It is known that theThe soil used in the embankment has a wet unit weight of 111 lb/ft3, moisture contentmoisture content of 23%, and Gs = 2.67. Complete the following tasks:(a) Determine the wet weight of the soil required to construct the first layer.(closest to the foundation soil) per foot (ft) of the embankment.b) On the day of construction there was a heavy rain that caused the soil used to reach a nearly saturated condition.used to reach a near saturated condition.
