The location survey of the proposed road passes through a rough terrain and crosses a small valley between two points along the center line of the proposed road. One of the points is at station 56 + 636.00 and at elevation (150.42 m.), the other point is at station 56 + 684.00 and at elevation (149.82 m.). The lowest point at the bottom of the valley is 23 m. from the highest point and has an elevation of its bottom equal to 140.64 m. The road passes through these three points. Al sections on this proposed roadway are three level sections having a width of roadway equal to 12 m. with side slope of 1.5: 1. Assume shrinkage factor to be 1.30. (a) Compute the cross-sectional area at station 56 + 659 in m². (b) Compute the volume of fill needed starting from the highest point of road to the lowest point of the valley in m³. (c) Compute the volume of fill needed from station 56 + 659 to 56 +684 in m³.
