At station 1+100 of a portion of a highway stretch has an area of 100 sq.m in cut while that of station 1+200 the area is 240 sq.m in cut. At station 1+100, the ground surface to the left of the center line is flat and the height of the right slope stake above the grade line is one half that of the left, while that of station 1+200, the height of the right slope stake is 3 times higher that of the left stake. The center cut at station 1+200 is 2.89. The width of the roadway is 10m with a side slope of 2:1. Determine the volume by end area method.

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.
