1. Which of the following is the primary objective of the 'road safety audit'?
A. To assess the durability of road surfaces
B. To evaluate the safety of a road or highway design
C. To review the construction cost estimates
D. To improve aesthetic features of roads
Answer: b) To evaluate the safety of a road or highway design
Rationale: A road safety audit aims to identify potential hazards and
recommend improvements to enhance road safety for all users.
2. In highway planning, what does the term 'right of way' refer to?
A. The legal authority to construct roads on specific land
B. The specific area designated for the road, including all lanes and
shoulders
C. The area designated for construction equipment
D. A lane where vehicles are allowed to speed
Answer: b) The specific area designated for the road, including all lanes and
shoulders
Rationale: 'Right of way' refers to the land or property designated for the
construction of roads, including lanes, shoulders, and any associated
infrastructure.
3. 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.
4. 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.
5. 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.
6. In NHA projects, what is the significance of a 'feasibility study'?
A. To assess the likelihood of project completion on time
B. To evaluate the environmental impact of the project
C. To determine whether the project is financially viable and technically
feasible
D. To predict future traffic patterns
Answer: c) To determine whether the project is financially viable and
technically feasible
Rationale: A feasibility study assesses the practicality, financial viability,
and technical aspects of a project, ensuring that it can be successfully
completed within the given constraints.
7. Which type of construction material is most commonly used for the
subbase layer of highways?
A. Concrete
B. Asphalt
C. Gravel
D. Steel
Answer: c) Gravel
Rationale: Gravel is commonly used for the subbase layer due to its ability
to provide drainage and support the layers above it.
A. To assess the durability of road surfaces
B. To evaluate the safety of a road or highway design
C. To review the construction cost estimates
