1. What is the primary purpose of a bridge foundation?
A. To increase traffic speed
B. To transfer structural loads safely into the supporting soil or
rock
C. To reduce the bridge width
D. To eliminate expansion joints
Rationale: Bridge foundations support the loads from piers,
abutments, and the superstructure and transfer those loads to
competent ground.
Correct answer: B. To transfer structural loads safely into the
supporting soil or rock
2. Which bridge component primarily supports the deck and
transfers loads to the substructure?
A. Superstructure
B. Approach slab
C. Drainage ditch
D. Wingwall
,Rationale: The superstructure includes components such as
girders and the deck that carry traffic loads and transfer them
to the substructure.
Correct answer: A. Superstructure
3. Which component supports the ends of a bridge and retains
the approach roadway?
A. Pier
B. Abutment
C. Girder
D. Bearing
Rationale: Abutments support the bridge ends and commonly
retain the approach embankment.
Correct answer: B. Abutment
4. What is the main function of a bridge pier?
A. Support intermediate portions of the superstructure
B. Provide pavement markings
C. Prevent concrete curing
D. Replace the bridge deck
Rationale: Piers provide intermediate vertical support where a
bridge spans multiple openings.
Correct answer: A. Support intermediate portions of the
superstructure
,5. What is the purpose of reinforcing steel in reinforced
concrete?
A. To provide tensile resistance
B. To make concrete waterproof
C. To replace aggregate
D. To eliminate curing
Rationale: Concrete is strong in compression but relatively
weak in tension. Reinforcing steel helps resist tensile and
flexural stresses.
Correct answer: A. To provide tensile resistance
6. Why is concrete curing important?
A. It removes all aggregate
B. It allows cement hydration and strength development
C. It increases concrete evaporation
D. It prevents concrete from setting
Rationale: Proper curing maintains favorable moisture and
temperature conditions for cement hydration and strength
development.
Correct answer: B. It allows cement hydration and strength
development
7. What does the water-cement ratio significantly influence?
, A. Concrete strength and durability
B. Bridge lane markings
C. Excavator horsepower
D. Rebar diameter only
Rationale: Excess water generally increases porosity and can
reduce concrete strength and durability after hardening.
Correct answer: A. Concrete strength and durability
8. What is the purpose of concrete formwork?
A. Shape and support fresh concrete until it can support itself
B. Replace reinforcing steel
C. Remove all moisture from concrete
D. Test soil density
Rationale: Forms provide the desired geometry and temporary
support for freshly placed concrete.
Correct answer: A. Shape and support fresh concrete until it can
support itself
9. What is a concrete slump test primarily used to evaluate?
A. Concrete temperature
B. Concrete workability/consistency
C. Rebar yield strength
D. Soil bearing capacity
