1. What is the primary purpose of bridge repair?
A. Improve the appearance only
B. Restore or maintain structural function and serviceability
C. Increase roadway speed limits
D. Eliminate all maintenance requirements
Correct Answer: B. Restore or maintain structural function and
serviceability
Rationale: Bridge repair addresses deterioration or damage so
the structure can safely perform its intended function.
2. Which bridge component primarily carries traffic loads
directly?
A. Superstructure
B. Landscaping
C. Drainage ditch
D. Sign support
Correct Answer: A. Superstructure
Rationale: The superstructure includes components such as
,decks, girders, and beams that carry traffic loads and transfer
them toward the supports.
3. What is the primary function of a bridge foundation?
A. Provide roadway markings
B. Transfer structural loads safely into the ground
C. Prevent vehicle noise
D. Support traffic signs
Correct Answer: B. Transfer structural loads safely into the
ground
Rationale: Foundations transfer loads from piers and
abutments to competent supporting soil or rock.
4. Which condition is a common sign of deterioration in
reinforced concrete?
A. Rust staining and cracking
B. New pavement markings
C. Clean expansion joints
D. Smooth traffic flow
Correct Answer: A. Rust staining and cracking
Rationale: Corroding reinforcement can cause rust staining,
cracking, delamination, and concrete spalling.
,5. What is concrete spalling?
A. Polishing concrete
B. Breaking or flaking away of concrete
C. Painting concrete
D. Increasing concrete strength
Correct Answer: B. Breaking or flaking away of concrete
Rationale: Spalling occurs when portions of concrete detach,
often because of reinforcement corrosion, freeze-thaw
damage, impact, or other deterioration.
6. Why is reinforcement corrosion particularly damaging to
concrete?
A. Corrosion products occupy more volume than the original
steel
B. Steel becomes lighter
C. Concrete becomes waterproof
D. Reinforcement disappears immediately
Correct Answer: A. Corrosion products occupy more volume
than the original steel
Rationale: Expansion from corrosion can create internal
pressure that cracks and dislodges surrounding concrete.
7. What should generally be done before repairing
deteriorated concrete?
A. Cover the deterioration with paint
, B. Identify and remove unsound concrete
C. Increase traffic loads
D. Add water to the concrete surface
Correct Answer: B. Identify and remove unsound concrete
Rationale: Sound repair requires removal of loose,
delaminated, or otherwise unsound material before
replacement.
8. What is delamination in concrete?
A. A separation between layers within the concrete
B. A type of bridge lighting
C. A method of welding
D. A drainage system
Correct Answer: A. A separation between layers within the
concrete
Rationale: Delamination is separation within the concrete,
often associated with reinforcement corrosion or freeze-thaw
deterioration.
9. Which test can help identify delaminated concrete?
A. Chain drag or hammer sounding
B. Traffic counting only
C. Paint thickness measurement
D. Tire pressure testing
