The main purpose of pavement design is to ensure long term durability. Proper design ensures the pavement can withstand traffic loads, environmental stresses, and other factors without excessive deterioration.
Which material is primarily used in flexible pavements?
A Gravel
B Concrete
C Asphalt
D Bitumen
Flexible pavements are commonly made with asphalt, a material known for its flexibility and ability to distribute traffic loads effectively, allowing the pavement to adjust to varying stress levels.
What is a rigid pavement made of?
A Concrete
B Steel
C Bitumen
D Gravel
Rigid pavements are made from concrete, which is strong and stiff. This type of pavement is best suited for high load traffic areas because of its durability and resistance to deformation.
What does a traffic survey measure?
A Speed limits
B Road aesthetics
C Road conditions
D Traffic volume
Traffic surveys are conducted to measure the number and type of vehicles passing through a road segment. This data helps engineers design roadways, plan expansions, and manage traffic flow effectively.
What is the main function of highway drainage systems?
A Traffic regulation
B Vehicle safety
C Flood control
D Surface aesthetic
The primary function of highway drainage systems is to control water flow, preventing flooding on the road surface. This ensures road stability, minimizes water damage, and improves safety for drivers.
Which of the following is a key advantage of flexible pavements?
A Rigid structure
B Cost efficiency
C Strength
D Durability
Flexible pavements are typically more cost effective than rigid pavements, both in terms of initial construction and maintenance costs. They are easier and quicker to construct, especially in less developed areas.
What does the term ‘soil stabilization’ refer to in road construction?
A Increasing soil strength
B Enhancing road aesthetics
C Reducing construction time
D Decreasing material costs
Soil stabilization is the process of improving the physical properties of soil to enhance its strength and stability. This is crucial for creating a durable foundation for roads and preventing issues like erosion.
What type of road is designed for high speed, long distance travel?
A Collector roads
B Rural roads
C Local roads
D Expressways
Expressways are designed for uninterrupted, high speed travel. They feature multiple lanes, limited access points, and no intersections, ensuring efficient long distance travel and reduced congestion.
Which material is typically used in rigid pavement construction?
A Asphalt
B Gravel
C Concrete
D Bitumen
Concrete is the primary material used in rigid pavements. It is known for its high strength, making it ideal for roads subjected to heavy loads and extreme weather conditions.
What is the main purpose of road markings?
A Improve aesthetics
B Decoration
C Traffic regulation
D Improve visibility
Road markings play a crucial role in regulating traffic by indicating lanes, pedestrian crossings, and other important traffic control information, ensuring safety and smooth flow of traffic.
What is ITS in the context of highways?
A International Transport Standards
B Intersection Traffic Signals
C Integrated Transport System
D Intelligent Traffic Systems
ITS refers to the use of technology to improve traffic flow, reduce congestion, and enhance road safety. It includes systems like real time traffic monitoring, signal adjustments, and vehicle communication technologies.
What is the purpose of toll roads?
A To speed up traffic
B To collect revenue for maintenance
C To increase road width
D To improve traffic flow
Toll roads are designed to generate revenue from users to fund road maintenance, repairs, and upgrades. This allows for better infrastructure management and quality.
What is the purpose of pavement evaluation?
A To increase speed
B To assess safety
C To assess road condition
D To improve aesthetics
Pavement evaluation involves assessing the structural and functional condition of a road to determine its suitability for continued use and to identify when repairs or upgrades are necessary.
What is the role of roadside vegetation in highway design?
A Prevent erosion
B Provide shade
C Increase traffic speed
D Improve aesthetics
Roadside vegetation helps to stabilize soil along embankments and prevent erosion. It also improves air quality and provides a natural barrier that can reduce noise and increase the overall environment of the highway.
Which of the following materials is commonly used in bituminous pavements?
A Steel
B Gravel
C Asphalt
D Concrete
Bituminous pavements are made using asphalt, which is a flexible and durable material. It is resistant to weather and traffic induced stresses, making it a preferred material for road surfaces, especially in areas with fluctuating temperatures.
