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.

An approach road for a bridge needs 60000 m3 of soil compacted to a void ratio of 0.7. There are two borrow pits A and B from where the required soil can be taken and transported to the site. The borrow pit A has void ratio 0.85 and borrow pit B has void ratio 0.95. If the cost of excavation of soiland transportation is Rs. 20/10 m3for area A and Rs. 22/10 m3for area B, which of the borrow area is more economical? G=2.67
QI/ A contractor excavates 10,000 m soil at moist unit weight of 17.5 kN/m' and moisture content of 10% from a borrow pit and transports it to a project site. The project has an area of 20,000 m2 to be filled with this compacted soil. If the required dry unit weight and moisture content of the compacted soil are 18.3 kN/m and 12.5% (assume there is no soil loss during transportation and compaction), what is the thickness of the compacted soil and how much water needs to be added?
