b. What is sight distance? Explain with sketches, how restrictions to sight distance occurs on highways.
(08 Marks)
OR
4 a. What are the conditions which necessitate a realignment project? List the steps involved in
realignment of a highway? (08 Marks)
b. The design speed of overtaking vehicle is 60 Kmph. The rate of acceleration of the above vehicle is
3.6 Kmph/sec. The difference in speed between overtaking and overtaken vehicle is 20 Kmph.
Calculate OSD as per IRC guidelines for a road with two way traffic. Draw the sketch of overtaking
zone. (08 Marks)

following data.
Details Pavement Type A Pavement Type B
Total cost per km, Rs. (lakhs) 3.30 6.20
Design life, years 5.00 12.00
Annual rate of interest 10.00 9.00
Salvage value after design life. Rs. Lakhs 2.10 3.00

0.9 m3/sec. Design the cross section and longitudinal slope of trapezoidal drain assuming the
bottom width of the trapezoidal section and cross slope suitably. The allowable velocity of flow in
the drain is 1.2 m/sec and Manning's roughness coefficient is 0.02. (08 Marks)
