Q1/The readings for cross sectional levelling at stations (0+00) and (1+00) are shown in the table below to construct a road with width (8m) and side slope (IV:2H). The garde line level is (22m). Compute the elevations of the points. draw the cross section using scale (1:100) and find the height of the fill at the stations? Station B.M. L. Distance (m) C.L. 0+00 R. B.S. 1.1 I.S. 1.47 F.S. H.I. Ele. (m) 20.5

Calculate: The bearing and final length of point AB  The slope of the gradeline joining the two points. Given: Point A : N= 3547m E= 755m Z= 699m Point B : N= 10489m E= 1086m Z= 633m

Define the term Slope Inclination Indicator.

Q6/ Below the elevation of points on the center of road project. If the D.L is start at elevation (25m) with ascending slope (0.5%). Find the heights of Fill and depths of cut for each points. с E F H I 100 150 200 250 300 350 400 25.7 25,2 24.8 26.6 26.8 27.2 27 60 28.0 Points A Dist. 0.0 C 26 B 50

(2) At station 3 + 020 the side slope of a road fill is 2:1. The width of the roadbed (including shoulder ditches) is 7m and the height of fill at the road center is 3m. The ground slope 8% upward to the right. At station 3+ 120 the cross section for the road is presented with a road width of 6m. 7.8 4 5.65 +3.84 +2.42 +4.25 +2.50 +2.12 Calculate the following: (a) the area of the station 3 + 020 (b) area at station 3 + 120 (c) Is the volume of cut sufficient to cover the volume of fill? How much volume of earth is needed or wasted for the given project. (Use end area method only)
