The cross section notes of the ground surface at a given station of a road survey shows that the ground is at an 8% sloping upward to the right for the first station, 100m from the first station the ground is now 9% sloping upward to the right. If the areas of irregular sections in cut at station are 32m 2 and 64m 2 respectively, where the width of subgrade is 8m with a side slopes of 2H:1V for the left slope stake and 3H:1V for the right slope stake for both section. a. Determine the difference in elevation between the ground and surface and the finished subgrade at the centerline of the proposed road for the first and second section of the surveyed roadway. b. Compute the distance between the left and right slope stake of the surveyed roadway.
