1. Which of the following is the primary purpose of a public
infrastructure inspection?
a) Increase project costs
b) Ensure compliance with standards
c) Recommend new construction materials
d) Design new infrastructure
b) Ensure compliance with standards
Inspections are conducted to verify that infrastructure meets applicable
codes, standards, and specifications.
2. When inspecting asphalt pavement, the term "rutting" refers to:
a) Cracks forming perpendicular to traffic
b) Depressions in wheel paths
c) Surface texture
d) Fading color
b) Depressions in wheel paths
Rutting indicates permanent deformation in the wheel paths, usually
caused by traffic loads.
3. What is the minimum slope recommended for a standard sidewalk
to ensure proper drainage?
,a) 0.5%
b) 1%
c) 2%
d) 5%
c) 2%
A slope of 2% ensures water drains off the sidewalk without pooling.
4. Which type of stormwater drainage system is most common in
urban areas?
a) Open channels
b) Swales
c) Closed conduit pipes
d) Natural streams
c) Closed conduit pipes
Urban areas typically use closed pipes to manage stormwater efficiently.
5. During bridge inspections, which type of defect is most critical to
structural safety?
a) Paint deterioration
b) Minor surface cracks
c) Structural cracks or corrosion of main members
d) Expansion joint debris
c) Structural cracks or corrosion of main members
Damage to primary load-carrying elements directly affects bridge
safety.
6. What is the primary tool for measuring pavement roughness?
a) Straightedge
b) Profilograph or inertial profiler
,c) Level
d) Tape measure
b) Profilograph or inertial profiler
These devices measure the International Roughness Index (IRI) for
pavement assessment.
7. Which of the following is considered a preventative maintenance
activity for streets?
a) Milling and overlay
b) Crack sealing
c) Complete reconstruction
d) Bridge replacement
b) Crack sealing
Crack sealing prevents water infiltration and extends pavement life.
8. When inspecting a sanitary sewer manhole, which condition
requires immediate repair?
a) Minor graffiti
b) Small sediment accumulation
c) Large structural cracks or displacement
d) Slight odor
c) Large structural cracks or displacement
Structural cracks can compromise manhole integrity and public safety.
9. What is the most common failure mode of reinforced concrete
curbs?
a) Spalling
b) Rusting of paint
c) Color fading
, d) Settlement of soil beneath sidewalks
a) Spalling
Spalling occurs due to freeze-thaw cycles or corrosion of reinforcing
steel.
10. For traffic signs, retroreflectivity is primarily important for:
a) Aesthetic appearance
b) Nighttime visibility
c) Ease of installation
d) Maintenance cost
b) Nighttime visibility
Retroreflective surfaces improve safety by making signs visible in low-
light conditions.
11. A crosswalk that shows fading markings should be:
a) Repainted immediately
b) Ignored
c) Repainted only if accidents occur
d) Relocated
a) Repainted immediately
Faded markings reduce pedestrian safety and driver awareness.
12. What is the main purpose of catch basins in stormwater systems?
a) Store water for irrigation
b) Filter large debris and convey water
c) Provide aesthetic value
d) Reduce traffic congestion
b) Filter large debris and convey water
Catch basins trap debris and sediment to protect downstream pipes.
