1. What is the primary objective of a bridge preservation
program?
A. Replace every bridge before it reaches 50 years of age
B. Extend bridge service life by applying appropriate
treatments before significant deterioration occurs
C. Eliminate the need for bridge inspections
D. Increase the design load of every bridge
Rationale: Bridge preservation focuses on maintaining existing
assets and slowing deterioration so that bridges remain safe
and functional for as long as practical. Timely preservation can
reduce the need for more expensive rehabilitation or
replacement.
2. Which statement best distinguishes bridge preservation
from bridge rehabilitation?
A. Preservation applies only to new bridges, while rehabilitation
applies only to old bridges
B. Preservation increases bridge capacity, while rehabilitation
,never does
C. Preservation generally consists of proactive treatments that
delay deterioration, while rehabilitation addresses more
substantial deficiencies
D. There is no meaningful distinction between the two
Rationale: Preservation is generally proactive and intended to
sustain an existing condition or slow deterioration.
Rehabilitation is typically more extensive and is used when a
bridge has developed significant deficiencies requiring
corrective work.
3. Why is preventive maintenance particularly important for
bridge preservation?
A. It guarantees that a bridge will never deteriorate
B. It eliminates the need for inspections
C. It addresses deterioration mechanisms before they become
more extensive and costly
D. It is required only for bridges with structural deficiencies
Rationale: Preventive maintenance is most effective when
applied before deterioration becomes severe. Addressing minor
problems early can prevent water, chlorides, corrosion, or other
deterioration mechanisms from causing more extensive
damage.
4. Which condition is generally most favorable for applying a
preservation treatment?
,A. The structural element has already failed
B. The bridge is in relatively good condition and the
deterioration mechanism can be controlled
C. The bridge requires complete replacement
D. The bridge has lost all load-carrying capacity
Rationale: Preservation is most effective when the bridge is still
in serviceable condition. Treatments applied before
deterioration becomes severe have a greater opportunity to
extend service life and protect the existing investment.
5. Which factor is most important when selecting a bridge
preservation treatment?
A. The treatment's appearance alone
B. The contractor's preferred method
C. The deterioration mechanism, bridge condition,
environment, and expected treatment performance
D. The age of the bridge alone
Rationale: Treatment selection should be based on the actual
problem being addressed. Understanding the deterioration
mechanism, existing condition, exposure environment,
constructability, and expected performance helps ensure that
the treatment is appropriate.
6. What is the primary purpose of routine bridge
maintenance?
, A. To redesign the bridge
B. To increase traffic capacity
C. To keep bridge components and systems functioning
properly and prevent avoidable deterioration
D. To replace all structural members periodically
Rationale: Routine maintenance addresses recurring needs such
as cleaning, debris removal, drainage maintenance, lubrication,
and minor repairs. These activities help preserve functionality
and prevent small problems from becoming major deficiencies.
7. Why is water management critical to bridge preservation?
A. Water always increases concrete strength
B. Water prevents steel corrosion
C. Uncontrolled water can accelerate corrosion, concrete
deterioration, erosion, and other damage mechanisms
D. Water has no significant effect on bridge durability
Rationale: Water is a major contributor to bridge deterioration.
It can transport chlorides, penetrate cracks and joints, promote
corrosion, freeze within porous materials, and cause erosion or
scour. Effective drainage and waterproofing therefore play
important preservation roles.
8. Which bridge component is particularly important for
controlling water movement away from the structure?
