The borrow material to construct an embankment has a dry unit weight of 86.2 pcf and a water content of 5%. The specific gravity of the solids is 2.64. The contract specifications require that the soil be placed in the fill at a ya of 115 pcf and a water content of 8%. a) How many cubic yards of borrow are required to construct an embankment having a 65,000-cy net volume? (15 points) b) If this material is to be compacted, estimate the production in compacted cubic yards per hour for a roller if its average speed will be 8 mph and it will cover 6 ft in one pass. The job specifications limit the compacted lift thickness to 6 inches and require 7 passes per lift. The company usually determine production based on a 50 min hour.
