1. Which department within NHA is primarily responsible for road design?
A. Financial Planning Department
B. Road Construction Department
C. Engineering Department
D. Public Relations Department
Answer: c) Engineering Department
Rationale: The Engineering Department is responsible for the technical
design, planning, and construction of highways, ensuring roads meet safety
and operational standards.
2. Which type of road surface is most effective at reducing road noise?
A. Concrete
B. Asphalt
C. Gravel
D. Steel
Answer: b) Asphalt
Rationale: Asphalt surfaces are more effective at reducing road noise
compared to concrete, as they offer a smoother finish and are more sound-
absorbent.
3. Which of the following is a characteristic of 'concrete pavement'?
A. More durable but less flexible than asphalt
,B. Cheaper than asphalt
C. Easier to repair than asphalt
D. Primarily used for low-traffic areas
Answer: a) More durable but less flexible than asphalt
Rationale: Concrete pavement is more durable and resistant to wear and
tear but is less flexible than asphalt, making it suitable for heavy traffic.
4. What does the term 'super elevation' refer to in highway design?
A. The maximum allowed elevation of a bridge
B. The change in road gradient at intersections
C. The banking of curves to reduce centrifugal force
D. The height of traffic signs on the highway
Answer: c) The banking of curves to reduce centrifugal force
Rationale: Super elevation refers to the banking or tilting of curves to
reduce the effects of centrifugal force on vehicles, enhancing safety during
turns.
5. Which type of road surface is most commonly used for highways?
A. Gravel
B. Concrete
C. Asphalt
D. Dirt
Answer: c) Asphalt
, Rationale: Asphalt is the most commonly used surface for highways due to
its durability, cost-effectiveness, and ability to withstand varying weather
conditions.
6. What is the function of an 'interchange' on a highway?
A. To connect multiple highways and provide access to local roads
B. To provide a location for fuel stations and rest stops
C. To separate lanes based on vehicle size
D. To manage traffic signals at intersections
Answer: a) To connect multiple highways and provide access to local roads
Rationale: Interchanges are used to connect different highways or local
roads, allowing vehicles to switch routes safely without disrupting traffic
flow.
7. Which of the following is a primary factor in the construction of
highways?
A. Soil quality and terrain
B. Air traffic management
C. River navigation
D. Tourism
Answer: a) Soil quality and terrain
Rationale: Soil quality, terrain, and topography are crucial in the planning
and construction of highways. These factors influence the choice of
materials, design, and construction methods.
