The soil borrow material to be used to construct a highway embankment has a density of 1570 kg/m3 , a water content of 6%, and the relative density of soil solids is 2.65 . The specifications require the soil to be compacted to a dry density of 1794 kg/m3 and the water content held to 13%. a. How many BCM are required to construct a 176,306 m3 embankment? b. How many liters of water must be added to the borrow material, on a cubic meter basis, assuming no loss by evaporation? c. If the compacted embankment becomes saturated at constant volume, what will be the water content and the density of the soil?
