Highway Engineering Questions (h2)

In this post, I will share some important questions which are frequently asked in competitive examinations such as SSC, UPSC and state PSCs.



  1. Arrange the following stages of surveys in a chronological order.


    1. Reconnaissance
    2. Preliminary surveys
    3. Map Study
    4. Final location and detail survey

    1. (3),(2),(1),(4)
    2. (3),(1),(2),(4)
    3. (1),(2),(3),(4)
    4. (2),(1),(3),(4)

    Answer: b

  2. Which of the following factors is the most important factor of all in controlling the geometric design elements of highways?


    1. Design speed
    2. Topography
    3. Traffic factors
    4. Design hourly volume and capacity

    View Answer
    Answer: a
    Design of almost every geometric design element of a road is dependent on the design speed.

  3. Consider the following statements and select the correct option.


    1. The skid occurs when the path travelled along the road surface is more than the circumferential movements of the wheel.
    2. Slip occurs when a wheel revolves more than the corresponding longitudinal movement along the road.

    1. only (1) is correct
    2. only (2) is correct
    3. both statements are wrong
    4. both statements are correct

  4. Which of the following pairs will give maximum friction?


    1. Wet road and new tyres with treads
    2. Dry road and smoothened tyres
    3. Dry road and new tyres with treads
    4. Wet road and smoothened tyres

    1. only (1)
    2. Both (1) and (2)
    3. Both (3) and (4)
    4. Only (3)


    View Answer
    Answer: b
    Smooth and worn out tyres offer higher friction factors on dry pavements then new tyres with treads because of a large area of contact.
    But on wet pavements, new tyres with good treads give higher friction factors than worn out tyres because the lubrication effect of water on the wet surface is reduced as the water entrapped between the tyre and pavement escapes into treads of the tyre.

  5. As per IRC, the longitudinal friction coefficient values for the calculation of stopping distance is ...


    1. 0.15 to 0.35
    2. 0.35 to 0.38
    3. 0.35 to 0.40
    4. 0.40 to 0.45

    View Answer
    Answer: c

  6. As per IRC, the value of lateral friction coefficient is ...


    1. 0.15
    2. 0.20
    3. 0.30
    4. 0.35

    View Answer
    Answer: a

  7. A good pavement has unevenness of less than ...


    1. 100 cm/km
    2. 150 cm/km
    3. 200 cm/km
    4. 250 cm/km

    View Answer
    Answer: b

  8. Which of the following pavement surfaces give good visibility at night?


    1. Light coloured or white pavement surface
    2. Blacktop pavement surface
    3. Both (a) and (b)
    4. Neither (a) nor (b)

    View Answer
    Answer: a

  9. What is the main objective of providing the camber?


    1. To prevent the entry of surface water into the subgrade
    2. To prevent the entry of surface water into the bituminous layers
    3. To remove the rainwater from the surface as quickly as possible
    4. All of the above

    View Answer
    Answer: c
    The pavement becomes very unsafe for vehicle operation at high speeds when the pavement is wet.

  10. Which of the following shapes of camber is prefered?


    1. Straight line
    2. Parabola
    3. Combination of (a) and (b)
    4. Any of the above

    View Answer
    Answer: c
