Question 1

The super elevation needed on a horizontal circular curve of 150m radius for a design speed of 60 kmph with coefficient of friction of 0.15 is

Question 2

For two major roads with divided carriageway crossing at right angle, a full clover leaf interchange with four indirect ramps is provided. Following statements are made on turning movements of vehicles to all directions from both roads. Identify the correct statement:

Question 3

The superelevation for a horizontal highway curve of radius 450 m and speed 80 kmph in mixed traffic condition will be ______%.

Question 4

The radius of a horizontal circular curve on a highway is 120 m. The design speed is 60
km/hour, and the design coefficient of lateral friction between the tyre and the road surface is 0.15. The estimated value of superelevation required (if full lateral friction is assumed to
develop), and the value of coefficient of friction needed (if no superelevation is provided) will, respectively, be

Question 5

If the difference in elevation of an edge of the pavement 9m wide and its crown is 15 cm, the camber of the pavement is

Question 6

In the absence of superelevation, the formation of pot holes, is generally
