1. What is the primary objective of a transportation structures
inspection program?
A. To determine whether a structure should be replaced immediately
B. To identify structural deficiencies, document condition, and support
decisions concerning safety, maintenance, repair, and rehabilitation
C. To determine the original construction cost of the structure
D. To calculate the annual traffic volume only
Answer: B. To identify structural deficiencies, document condition,
and support decisions concerning safety, maintenance, repair, and
rehabilitation
Rationale: The fundamental purpose of structural inspection is to
evaluate existing conditions and identify deficiencies that could affect
structural safety, serviceability, durability, or functionality. Inspection
information is then used to prioritize maintenance, repairs,
rehabilitation, load restrictions, and, when necessary, replacement.
2. During an inspection of a bridge, an inspector observes a
significant crack in a reinforced-concrete beam. What should the
inspector do first?
1
,A. Immediately seal the crack without further investigation
B. Ignore it because all concrete cracks are cosmetic
C. Evaluate and document the crack's location, orientation, width,
length, depth if determinable, and associated distress
D. Paint over the crack to prevent water intrusion
Answer: C. Evaluate and document the crack's location, orientation,
width, length, depth if determinable, and associated distress
Rationale: A crack cannot be properly evaluated simply by observing
that one exists. Its characteristics and surrounding conditions must be
documented so that its significance can be determined. Cracking
associated with corrosion, shear distress, flexural distress, movement,
settlement, or deterioration can have substantially different
implications.
3. Which condition is generally most concerning when evaluating
cracking in a reinforced-concrete flexural member?
A. A very fine, isolated surface crack in a noncritical area
B. Cracking that is associated with reinforcement corrosion, significant
section loss, or structural distress
C. A construction joint that is properly detailed
D. A superficial shrinkage crack in an architectural surface
Answer: B. Cracking that is associated with reinforcement
corrosion, significant section loss, or structural distress
Rationale: Cracks become particularly significant when they provide
evidence of an active deterioration mechanism or structural distress.
Corrosion-related cracking can indicate expanding reinforcement and
loss of concrete protection, while structural cracks may indicate
overstress or inadequate load-carrying capacity.

, 4. What is the principal concern when reinforcing steel in a
reinforced-concrete bridge member becomes heavily corroded?
A. The concrete becomes lighter
B. Corrosion can cause loss of steel cross-sectional area and
deterioration or spalling of surrounding concrete
C. The member automatically becomes stronger
D. Corrosion only affects the appearance of the structure
Answer: B. Corrosion can cause loss of steel cross-sectional area and
deterioration or spalling of surrounding concrete
Rationale: Reinforcement corrosion produces expansive corrosion
products that can crack and delaminate the surrounding concrete.
Continued corrosion can reduce reinforcement area, bond, and
anchorage, potentially compromising the structural capacity and
durability of the member.
5. What is the most appropriate purpose of sounding concrete during
an inspection?
A. To determine the concrete's exact compressive strength
B. To identify potentially delaminated or hollow-sounding areas that
may indicate deterioration beneath the surface
C. To measure bridge deflection
D. To determine the bridge's design load
Answer: B. To identify potentially delaminated or hollow-sounding
areas that may indicate deterioration beneath the surface
Rationale: Sounding with appropriate tools can help identify areas
where concrete has separated from underlying concrete or
reinforcement because of corrosion, freeze-thaw damage, inadequate
consolidation, or other deterioration mechanisms. Sounding does not
directly determine compressive strength.

, 6. A bridge inspector observes concrete spalling over a reinforcing
bar. Which condition should receive particular attention?
A. Whether the spalled area is near a source of moisture or chloride
contamination
B. Whether the concrete was originally painted
C. Whether the bridge has a decorative railing
D. Whether the roadway markings are faded
Answer: A. Whether the spalled area is near a source of moisture or
chloride contamination
Rationale: Moisture and chlorides can accelerate reinforcement
corrosion. Spalling over reinforcement may therefore be evidence of
an ongoing corrosion process rather than an isolated surface defect.
The inspector should evaluate the surrounding concrete and
reinforcement condition as well.
7. Which bridge component is primarily intended to transfer traffic
loads from the deck to the supporting superstructure while
accommodating movement?
A. Expansion joint
B. Bearing
C. Drainage inlet
D. Guardrail reflector
Answer: B. Bearing
Rationale: Bearings transfer forces between structural components
while allowing specified movements and rotations. Depending on the
bridge system, bearings may accommodate thermal expansion,
contraction, rotation, and other movements while transmitting vertical
and horizontal forces.
