The soil borrow material to be used to construct a highway embankment has a mass unit weight of 99.0 lb./cf and a water content of 6.5%, and the specific gravity of the soil solids is 2.65. The specifications require that the soil be placed in the fill so that the dry unit weight is 112 lb./cf and the water content be held to 6%. A. How many cubic yards of borrow are required to construct an embankment having a 600,000-cy net section volume?
B. How many gallons of water must be added per cubic yard of material assuming no loss evaporation?
C. If the compacted fill becomes saturated at constant volume, what will be the water content and unit weight?
