Questions

  1. Q1

    1. a)

      The design speed of a highway is 90 kmph. There is horizontal curve of radius 200 m on a certain section. Allowable limit of lateral coefficient of friction is 0.15. i) Calculate the superelevation required to maintain this speed. ii) If the maximum allowable superelevation is 7.0 percent, calculate the allowable speed on this horizontal curve.

  6. Q6

    1. a)

      A two lane two way road is carrying an initial traffic of 1600 Commercial Vehicles per day (CVPD) is to be strengthened to cater the need of growing traffic.
