1. Which document primarily governs the design standards for public
highways in Minnesota?
A. Minnesota Plumbing Code
B. AASHTO Green Book
C. National Electrical Code
D. OSHA Handbook
B. AASHTO Green Book
The AASHTO Green Book provides nationally recognized guidance for
geometric highway design, including lane widths, sight distance, and
alignment standards commonly adopted by Minnesota transportation
agencies.
, 2. What is the primary purpose of a highway subgrade?
A. To support pavement loads
B. To increase pavement color visibility
C. To reduce bridge expansion
D. To improve signage placement
A. To support pavement loads
The subgrade is the natural soil layer prepared to support pavement
structures and traffic loads. Its stability greatly affects pavement
performance and longevity.
3. Which surveying instrument is most commonly used to measure
horizontal and vertical angles in highway construction?
A. Barometer
B. Total station
C. Thermometer
D. Micrometer
B. Total station
A total station combines electronic distance measurement and angular
measurement capabilities, making it essential for highway layout and
construction surveying.
, 4. What is the standard unit for measuring roadway gradient?
A. Degrees Celsius
B. Pounds per square inch
C. Percent slope
D. Cubic feet
C. Percent slope
Roadway gradient is expressed as percent slope, calculated by dividing
vertical rise by horizontal distance and multiplying by 100.
5. Which pavement distress is characterized by interconnected cracks
resembling alligator skin?
A. Bleeding
B. Rutting
C. Alligator cracking
D. Polishing
C. Alligator cracking
Alligator cracking results from repeated traffic loading and structural
fatigue in asphalt pavements, often indicating base or subgrade failure.
6. What is the primary function of aggregate in asphalt pavement?
, A. Increase electrical conductivity
B. Provide structural strength and stability
C. Reduce traffic signs
D. Prevent snow accumulation
B. Provide structural strength and stability
Aggregates form the structural skeleton of asphalt pavement and
contribute significantly to load distribution and durability.
7. Which traffic control device warns drivers of upcoming road
conditions?
A. Regulatory sign
B. Warning sign
C. Guide sign
D. Pavement marker
B. Warning sign
Warning signs alert motorists to hazards or changes in roadway conditions
ahead, helping improve driver response and safety.
8. What is the typical color of warning signs in highway engineering?
A. Blue
B. Green
