B. Bridge load ratings
C. Traffic control devices
D. Asphalt mixing procedures
• Answer: C. Traffic control devices
The Manual on Uniform Traffic Control Devices standardizes road
signage and markings.
4. Which of the following best describes a "frost heave"?
A. Pavement damage caused by heavy trucks
B. Upward soil movement due to freeze-thaw cycles
C. Settlement of road subgrade due to water
D. Bridge pier cracking
, • Answer: B. Upward soil movement due to freeze-thaw cycles
Common in Alaska’s permafrost areas, frost heave impacts road
alignment.
5. Before highway construction begins, the contractor must:
A. Submit an environmental impact statement
B. Obtain permits and approvals
C. Remove all vegetation
D. Start excavation
• Answer: B. Obtain permits and approvals
Permitting ensures environmental and legal compliance.
Roadway Materials
6. Which material is most commonly used for Alaska road surfacing?
A. Gravel
B. Asphalt concrete
C. Portland cement concrete
D. Brick
• Answer: B. Asphalt concrete
Asphalt is flexible, cost-effective, and suitable for cold climates.
7. What is the purpose of geotextiles in road construction?
A. Increase concrete strength
B. Prevent soil erosion and separation
C. Reduce asphalt oxidation
D. Replace gravel layers
• Answer: B. Prevent soil erosion and separation
Geotextiles stabilize soil and improve drainage.
8. In asphalt paving, the term “lift” refers to:
A. A type of crane used
B. A layer of asphalt placed and compacted
C. A bridge support system
D. A slope stabilization method
• Answer: B. A layer of asphalt placed and compacted
Asphalt is applied in lifts to achieve thickness and compaction.
9. The main binder in asphalt concrete is:
A. Lime
,B. Bitumen
C. Portland cement
D. Epoxy resin
• Answer: B. Bitumen
Bitumen binds aggregate particles together in asphalt.
10. Which type of aggregate is preferred in Alaska to resist freeze-thaw cycles?
A. Soft shale
B. Porous limestone
C. Hard, durable granite or basalt
D. Sandstone
• Answer: C. Hard, durable granite or basalt
Dense, durable aggregates reduce frost damage.
Bridge Construction
11. The structural element that transfers loads from a bridge deck to foundations
is:
A. Parapet
B. Abutment
C. Pier
D. Both B and C
• Answer: D. Both B and C
Abutments and piers carry deck loads to foundations.
12. Which bridge type is most commonly used for Alaska highway crossings?
A. Suspension
B. Truss
C. Girder
D. Arch
• Answer: C. Girder
Steel or concrete girder bridges are economical and widely used.
13. What is the main purpose of bridge bearings?
A. Support traffic loads
B. Allow controlled movement and rotation
C. Provide decorative finishing
D. Reduce frost action
, • Answer: B. Allow controlled movement and rotation
Bearings transfer loads while accommodating expansion and contraction.
14. Which inspection is mandatory after bridge construction?
A. Biennial FHWA inspection
B. Monthly structural check
C. OSHA safety audit
D. Materials testing only
• Answer: A. Biennial FHWA inspection
Federal regulations require inspection of bridges every two years.
15. The primary load considered in bridge design is:
A. Pedestrian load
B. Wind load
C. Vehicle load (live load)
D. Dead load only
• Answer: C. Vehicle load (live load)
Highway bridges are designed mainly for vehicle loads.
Construction Safety
16. What is the minimum distance for placing warning signs ahead of a work
zone on rural highways in Alaska?
A. 50 ft
B. 100 ft
C. 500 ft
D. 1,000 ft
• Answer: C. 500 ft
Adequate distance allows drivers time to adjust.
17. Which federal law governs worker safety on Alaska construction sites?
A. MUTCD
B. OSHA Act
C. Clean Water Act
D. ADA
• Answer: B. OSHA Act
OSHA standards apply to highway and bridge projects.
18. Fall protection is required for workers at heights above:
A. 4 ft
Alaska?
A. FHWA
