1. During bridge deck inspection, which condition most commonly
indicates active chloride-induced reinforcement corrosion in reinforced
concrete structures?
A. Uniform surface discoloration without cracking
B. Longitudinal cracking parallel to reinforcing steel with rust staining
C. Smooth honeycombing near construction joints only
D. Surface laitance caused by improper curing
B. Longitudinal cracking parallel to reinforcing steel with rust staining
Rationale: Chloride intrusion causes reinforcing steel corrosion, producing
expansive rust products that create longitudinal cracking along reinforcing
bars and visible rust staining. These symptoms are strong indicators of
active deterioration requiring corrective evaluation and repair.
2. Which document primarily establishes inspection tolerances and
acceptance criteria for structural steel bridge fabrication in Maryland
highway projects?
,A. OSHA Construction Standards
B. ACI 318 Building Code Requirements
C. AWS D1.5 Bridge Welding Code
D. MUTCD Traffic Control Manual
C. AWS D1.5 Bridge Welding Code
Rationale: AWS D1.5 specifically governs bridge welding requirements,
including fabrication tolerances, welding procedures, inspection criteria,
and acceptance standards applicable to steel bridge construction projects.
3. A bridge inspector observes scaling and delamination on a concrete
bridge deck. What is the MOST likely contributing factor?
A. Excessive carbonation only
B. Repeated freeze-thaw cycles combined with deicing salts
C. Ultraviolet radiation exposure
D. Differential settlement of abutments only
B. Repeated freeze-thaw cycles combined with deicing salts
Rationale: Freeze-thaw deterioration and chloride contamination from
deicing salts commonly cause scaling, cracking, and delamination in bridge
decks, especially in climates with seasonal freezing conditions.
4. What is the PRIMARY purpose of nondestructive testing during bridge
steel inspections?
A. To increase steel yield strength
B. To determine asphalt pavement thickness
C. To detect internal defects without damaging components
D. To verify concrete compressive strength only
C. To detect internal defects without damaging components
,Rationale: Nondestructive testing methods such as ultrasonic testing and
magnetic particle inspection help inspectors identify hidden defects, cracks,
and discontinuities without harming structural elements.
5. Which inspection method is MOST effective for detecting subsurface
delamination in reinforced concrete bridge decks?
A. Visual inspection only
B. Dye penetrant testing
C. Chain drag sounding
D. Torque wrench testing
C. Chain drag sounding
Rationale: Chain drag sounding produces distinct acoustic responses that
help inspectors identify hollow or delaminated areas beneath the concrete
surface, making it a widely used field technique.
6. When inspecting bridge bearings, which condition represents the
GREATEST immediate structural concern?
A. Minor paint peeling on bearing plates
B. Slight dust accumulation around anchor bolts
C. Frozen or seized bearings preventing thermal movement
D. Surface oxidation on galvanized components
C. Frozen or seized bearings preventing thermal movement
Rationale: Bearings must accommodate thermal expansion and
contraction. Frozen bearings can transfer unintended stresses into bridge
components, causing cracking, distortion, and structural damage.
7. Which factor MOST directly affects the load-carrying capacity of a steel
girder bridge?
, A. Color of protective coating
B. Condition of structural members and connections
C. Pavement striping layout
D. Width of approach shoulders only
B. Condition of structural members and connections
Rationale: Structural integrity depends on member condition, cross-
sectional area, connection performance, and material soundness.
Deterioration or damage reduces load-carrying capacity significantly.
8. What is the PRIMARY reason inspectors verify proper concrete curing
procedures during bridge construction?
A. To improve paint adhesion
B. To reduce labor costs
C. To achieve intended strength and durability
D. To increase steel ductility
C. To achieve intended strength and durability
Rationale: Proper curing maintains moisture and temperature conditions
necessary for hydration, ensuring concrete develops required strength,
durability, and resistance to environmental deterioration.
9. Which bridge component primarily transfers loads from the
superstructure to the foundation?
A. Expansion joints
B. Bearings and substructure elements
C. Bridge railings
D. Approach slabs only
B. Bearings and substructure elements
