2. Given below are the ordinates of the mass diagram for a highway project. No haulage is possible pass station 38+50, so this project may be considered the end of the project for this purpose. The free-haul distance is 500 ft. Draw the mass diagram and determine a) the volume of excavation and embankment, b) the quantities of overhaul (station yards), waste and borrow; and c) the direction of haul.
