3. A road is to be constructed on the side of a hill having a cross fall of 1 in 50 at right angles to the center-line of the road: the side slopes are to be 1 in 2 in cut and 1 in 3 in fill; the formation is 20 m wide and level. Find the position of the center-line of the road with respect to the point of intersection of the formation and the natural ground a. To give equality of cut and fill. b. So that the area of cut shall be 0.8 of the area of fill, in order to allow for bulking.
