The soil borrow material to be used to construct a highway embankment has a mass unit weight of 98.0 pcf, a water content of 6%, and the specific gravity of the soil solids is 2.65. The specifications require the soil be compacted to a dry unit weight of 112 lb per cf and the water content be held to 13%. (279,355 bey, 21.0 gal/bey borrow, 18%, 132.1 lb/cf) Required:
a. How many cubic yards of borrow are required to construct an embankment having a 230,600-cy net section volume?
b. How many gallons of water must be added to borrow material, on a per cubic yard basis, assuming no loss by evaporation?
