What is the primary function of flexible pavements?
A High speed
B Low cost
C Aesthetic appeal
D Load distribution
Flexible pavements are designed to distribute the loads from traffic over a large area. They are made from materials like bitumen, which provide flexibility and adaptability to load stresses, preventing cracks.
What is the main material used in rigid pavements?
A Concrete
B Wood
C Bitumen
D Gravel
Rigid pavements are primarily constructed with concrete, known for its high strength and ability to resist deformation under heavy traffic loads. Concrete pavements are durable but less flexible compared to bituminous ones.
What does a traffic survey help determine?
A Road curvature
B Traffic volume
C Traffic speed
D Road material
Traffic surveys collect data on vehicle counts, types, and travel patterns. This data is essential for planning road capacity, designing intersections, and improving traffic flow and safety on highways.
What is the purpose of drainage design in highways?
A To reduce traffic
B To improve speed
C To remove water
D To increase aesthetic value
Drainage design ensures that water does not accumulate on road surfaces, which could lead to pavement damage, flooding, and safety hazards. Proper drainage enhances road durability and prevents erosion.
Which road feature allows vehicles to travel at higher speeds?
A Intersections
B Crosswalks
C Curves
D Expressways
Expressways are designed for high-speed, uninterrupted travel. They have no intersections or stoplights, ensuring continuous traffic flow and reducing the chance of accidents, making them suitable for long-distance travel.
What is the purpose of road markings?
A To beautify roads
B To increase traffic
C To guide drivers
D To reduce costs
Road markings provide visual instructions for drivers, indicating lanes, pedestrian crossings, stop signs, and directions. They help maintain traffic flow and ensure road safety, especially at night or in poor weather.
What material is commonly used in bituminous pavements?
A Asphalt
B Gravel
C Concrete
D Soil
Bituminous pavements are made using asphalt, a petroleum based product that is both flexible and water resistant. Asphalt is widely used because it provides durability and smooth surfaces for traffic.
What is the primary reason for widening roads?
A To reduce noise
B To handle more traffic
C To reduce costs
D To enhance beauty
Road widening is done to accommodate increased traffic volumes. By adding more lanes, it helps improve traffic flow, reduce congestion, and enhance road safety.
What is the benefit of soil stabilization in road construction?
A Prevents flooding
B Lowers construction cost
C Strengthens road base
D Faster construction
Soil stabilization improves the strength and durability of the soil used in road construction, ensuring a more stable base. It prevents erosion and increases the lifespan of the pavement.
What is the main purpose of noise barriers along highways?
A To provide shade
B To reduce traffic
C To block noise
D To improve road safety
Noise barriers are designed to reduce the impact of traffic noise on nearby communities. By reflecting or absorbing sound, they help improve the quality of life for people living close to busy highways.
What does ITS stand for in highway engineering?
A International Transport Standards
B International Traffic System
C Intelligent Traffic Systems
D Integrated Transport Service
ITS refers to the use of advanced technologies to manage traffic efficiently, improve safety, and reduce congestion. These systems include real time traffic monitoring, signal control, and vehicle communication systems.
Which type of pavement is best suited for high traffic areas?
A Rigid pavement
B Wooden pavement
C Flexible pavement
D Gravel pavement
Rigid pavements, made of concrete, are well suited for high traffic areas because they are more durable and resistant to deformation compared to flexible pavements. They can handle heavy loads better.
What is the role of pavement evaluation?
A To select road material
B To plan traffic flow
C To assess pavement condition
D To check aesthetic quality
Pavement evaluation involves inspecting the road surface to determine its condition. It helps identify cracks, ruts, or surface deterioration, guiding decisions on maintenance and rehabilitation needs.
What is the function of roadside vegetation in highways?
A To prevent erosion
B To reduce traffic speed
C To enhance visibility
D To block traffic
Roadside vegetation helps control erosion by stabilizing soil along highway embankments. It also contributes to environmental benefits, such as air purification and providing habitats for wildlife.
What is a toll road designed for?
A To widen lanes
B To collect fees for road use
C To prevent accidents
D To increase traffic speed
Toll roads are designed to generate revenue for road maintenance and construction. Users pay a fee to access the road, helping fund ongoing infrastructure projects and upkeep.
