Domain 1: Highway Maintenance Fundamentals
Question 1 — Roadway Maintenance
What is the primary purpose of routine highway maintenance?
A. To increase traffic speed
B. To preserve the roadway and keep it safe and functional
C. To eliminate all future repairs
D. To reduce the number of roadway signs
Answer: B. To preserve the roadway and keep it safe and functional
Rationale: Routine maintenance preserves pavement, drainage systems, signs,
shoulders, and other highway components while helping maintain safe operating
conditions.
Question 2 — Pavement Distress
A pothole is best described as:
A. A raised pavement ridge
B. A pavement marking
C. A localized hole or depression caused by pavement deterioration
D. A drainage ditch
Answer: C. A localized hole or depression caused by pavement deterioration
,Rationale: Potholes are localized areas where pavement material has broken
away, commonly due to moisture, traffic, freeze-thaw cycles, and underlying
pavement deterioration.
Question 3 — Pavement Cracking
Alligator cracking is characterized by:
A. A single straight crack across the roadway
B. A network of interconnected cracks resembling reptile skin
C. A crack found only in concrete curbs
D. A crack caused exclusively by paint
Answer: B. A network of interconnected cracks resembling reptile skin
Rationale: Alligator cracking forms interconnected patterns and is commonly
associated with structural pavement problems, particularly inadequate support or
repeated loading.
Question 4 — Shoulder Maintenance
A highway shoulder primarily provides:
A. A permanent travel lane
B. Lateral support and an area for emergency stopping
C. A location for storing construction equipment
D. A replacement for the roadway drainage system
Answer: B. Lateral support and an area for emergency stopping
Rationale: Shoulders provide structural support to pavement edges and may
provide a safer area for disabled vehicles or emergency activities when conditions
permit.
Question 5 — Roadway Crown
The crown of a roadway is designed primarily to:
,A. Increase pavement thickness
B. Allow water to drain toward the sides of the roadway
C. Prevent vehicles from changing lanes
D. Increase shoulder width
Answer: B. Allow water to drain toward the sides of the roadway
Rationale: The crown creates a cross slope that directs surface water away from
the center of the roadway, reducing standing water and pavement damage.
Domain 2: Drainage and Culverts
Question 6 — Drainage
The primary purpose of roadway drainage is to:
A. Increase pavement temperature
B. Remove water from the roadway and surrounding infrastructure
C. Increase traffic volume
D. Reduce road width
Answer: B. Remove water from the roadway and surrounding infrastructure
Rationale: Proper drainage protects pavement and the roadway foundation while
reducing standing water, erosion, and other moisture-related problems.
Question 7 — Culvert
A culvert is primarily used to:
A. Mark a traffic lane
B. Carry water beneath a roadway or other obstruction
C. Store road salt
D. Support a traffic signal
Answer: B. Carry water beneath a roadway or other obstruction
Rationale: Culverts allow streams, drainage flows, and stormwater to pass
underneath roads while maintaining the roadway above.
, Question 8 — Clogged Drainage
A clogged roadside drainage inlet can cause:
A. Improved pavement strength
B. Water to accumulate on or near the roadway
C. Increased lane width
D. Improved visibility
Answer: B. Water to accumulate on or near the roadway
Rationale: Blocked inlets prevent water from entering the drainage system,
potentially causing ponding, flooding, erosion, and pavement deterioration.
Question 9 — Ditch Maintenance
A roadside ditch primarily functions to:
A. Store traffic-control devices
B. Collect and convey surface water away from the roadway
C. Provide a permanent pedestrian path
D. Increase pavement friction
Answer: B. Collect and convey surface water away from the roadway
Rationale: Properly shaped and maintained ditches direct runoff away from the
roadway and toward appropriate drainage outlets.
Question 10 — Erosion
Vegetation along an exposed roadside slope can help:
A. Increase soil erosion
B. Stabilize soil and reduce erosion
C. Block all drainage
D. Reduce pavement thickness
Answer: B. Stabilize soil and reduce erosion
