Q5/ The information below was taken from Longitudinal survey of road project. Draw the longitudinal section for the road, if the Hs (1:500) and the Vs (1:50). Calculate the slope between first and last point of the road. Draw the D.L starting from the elevation (23.7 m) with ascending slope (1%). Calculate the heights of Fill and depths of Cut for each points. DG)E() pi 10 20 30 40 50 60 70 80 90 25 25.6 25.8 26.10 25.90 25. lo 24.0 243 24.2 25.10 25.50

Calculate the minimum slope on which the channel shown in figurebelow must be laid if it is to carry 1.416 m3/s of water with a depth of0.61 m. The sides and bottom of the channel are made of formed, unfinished concrete.

At station 95+220, the center height of the road is 4.5 m cut, while at station 95+300, it is 2.6 m fill. The ground between station 95+220 to the other station has a uniform slope of -6.5%. What is the grade of the road?

7) A straight section of a proposed road having a formation width of 10.00 m is to be constructed as a cutting having side slopes of 1 in 2. A cross-section is to be taken at chainage 1225 m, where the depth of dig to the proposed formation level is to be 4.82 m. At this crosssection, the transverse slope at right angles to the proposed centre line falls from left to right but changes at the proposed centre line from a fall of 1 in 11 to a fall of 1 in 17. Calculate the area of cut required at this cross-section.
