solve it for number "7".
Question 1. Part A (12 marks) A short section of road, has the chainages, existing engineering ground level, and required formation levels shown in Table 1. Station (m) 0 100 200 300 400 500 Ground Level (m) 32.5 30 28 28 28 27 Formation level im) 31.5 30.3 29.1 28.1 27.1 26.1 Table 1: Existing ground level and required formation level against chainage The width of the formation to be prepared is Xm. Cuts have a batter of 1:1 and embankments have a batter of 12 if the shrinkage factor is SF, use a table to determine the mass haul ordinates, for each station on the short section of carriageway, and thus sketch the Mass Haul Diagram (MHD) The values of X Y, Z and SF are determined from Table 2 below, by the last digit of your Student ID (for example. Student ID 10983907 would use the set of variables) Cutting slope Embankment Slope Shrinkage Student ID "last digit Width (m) Factor Y z SF 0 2. 3 0.75 1 12 2.3 2 0.8 2 13 2.5 3 0.85 3 14 2.7 2 0.9 4 15 3 2 0.95 5 15 2 3 0.95 6 14 2.3 2 0.9 7 13 2.5 3 0.85 8 12 2.7 2 0.8 9 11 3 2 0.75 Table 2: Values of X, Y, Z and SF for all Student IDs a. Compile a table showing all relevant values so as to be able to draw a MHD. b. Show hand calculations for all values entered into the table. Sketch MHD. d. On the MHD sketch, draw the natural ground level and the formation level (different scale) for the various chainages. e. Confirm the significance of the highest point on the MHD curve. f. If I draw a horizontal line along the-500 ordinate from one point on the MHD curve to an adjacent point, what can you deduce from the formation natural ground pilot? Question 1.
