1. Which of the following is a common reason for deck cracking on
concrete bridges?
A. Excessive wind loads
B. Subgrade instability
C. Shrinkage and thermal movement
D. Poor painting techniques
Shrinkage and thermal movement can cause concrete to expand or
contract, leading to surface cracking if not properly managed.
2. What is the primary purpose of bridge bearings?
A. To support lighting systems
B. To prevent bridge collapse
C. To allow controlled movement of the superstructure
D. To drain rainwater
Bearings accommodate movements due to thermal expansion, contraction,
and load shifts without damaging the bridge.
,3. Which of the following materials is typically used in bridge expansion
joints?
A. Polyethylene
B. Neoprene
C. Aluminum
D. Fiberglass
Neoprene is flexible, durable, and weather-resistant, making it ideal for
expansion joints.
4. Which method is commonly used to detect internal cracks in steel
bridge components?
A. Visual inspection
B. Tap testing
C. Ultrasonic testing
D. Load testing
Ultrasonic testing uses sound waves to identify internal flaws in metal
structures.
5. What is the best practice for removing rust from steel bridge
components prior to painting?
A. Power washing
B. Acid etching
C. Sandblasting
D. Wire brushing
Sandblasting thoroughly cleans steel surfaces and ensures better paint
adhesion.
6. What type of bridge uses cables directly connected from the towers to
the deck?
A. Arch bridge
B. Suspension bridge
C. Cable-stayed bridge
, D. Truss bridge
Cable-stayed bridges use straight cables that run directly from towers to
the deck.
7. What does "scour" refer to in bridge maintenance?
A. Damage from bird droppings
B. Cracking due to earthquakes
C. Erosion of soil around bridge foundations
D. Rusting of rebar
Scour is the removal of sediment from around bridge piers or abutments,
often caused by water flow.
8. Which inspection frequency is mandated for bridges under the National
Bridge Inspection Standards (NBIS)?
A. Annually
B. Every 3 years
C. Every 2 years
D. Every 5 years
NBIS requires inspections every two years unless conditions justify more
frequent checks.
9. What personal protective equipment (PPE) is mandatory when working
on bridge decks near traffic?
A. Safety goggles
B. Hard hat
C. Gloves
D. High-visibility vest
High-visibility clothing is critical for worker safety in traffic zones.
10. When performing welding on a bridge, which document ensures
procedures meet standards?
A. Work Order
B. Structural Load Chart
