The centre line of a proposed road of formation width 12.00 m is to fall at a slope of 1 in 100 from chainage 50 m to chainage 150 m. The existing ground levels on the centre line at chainages 50 m, 100 m and 150 m are 71.62 m, 72.34 m and 69.31 m, respectively, and the ground slopes at 1 in 3 at right angles to the proposed centre line. If the centre line formation level at chainage 50 m is 71.22 m and the side slopes are to be 1 in 1 for cut and 1 in 2 for fill, calculate the volumes of cut and fill between chainages 50 m and 150 m.

Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.
