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%.
