A 1 km road is to be constructed in existing ground level having reduced levels 54.1, 53.8, 53.5, 53.5, 54.3, 54.6, 54.9, 54.5, 54.7 and 54.3 meters at 100 m intervals as shown in Figure 1. A required reduced level at station 1 is 55 meter and the downward gradient is 1 in 1000. The width of the road at formation level is 8 meter. To allow for drainage the road will have a slope of about 1:50 from the centre to the edge of the concrete drainage. a. Calculate the volume of Earthwork. [17 marks] b. Determine the number of trucks needed to transport the net cut/fill material if the swell of material is 20%. [3

Question
A 1 km road is to be constructed in existing ground level having reduced levels 54.1, 53.8, 53.5, 53.5,
54.3, 54.6, 54.9, 54.5, 54.7 and 54.3 meters at 100 m intervals as shown in Figure 1. A required
reduced level at station 1 is 55 meter and the downward gradient is 1 in 1000. The width of the road
at formation level is 8 meter. To allow for drainage the road will have a slope of about 1:50 from the
centre to the edge of the concrete drainage.
a. Calculate the volume of Earthwork.
[17 marks]
b. Determine the number of trucks needed to transport the net cut/fill material if the swell of
material is 20%.
