1. What is the primary purpose of asphalt binder in pavement?
A. To increase pavement color
B. To act as a binding agent for aggregate
C. To reduce construction cost
D. To speed up compaction
Correct Answer: B. To act as a binding agent for aggregate
Rationale: Asphalt binder coats and holds aggregate particles
together, providing strength and flexibility to the pavement
structure.
2. What does proper compaction of asphalt primarily ensure?
A. Faster cooling
B. Higher air voids
C. Pavement density and durability
D. Increased water absorption
Correct Answer: C. Pavement density and durability
Rationale: Proper compaction reduces air voids, increasing density
and improving pavement strength and lifespan.
3. Which factor most affects asphalt mix workability?
A. Aggregate color
B. Temperature of the mix
C. Traffic volume
D. Subgrade slope
, Correct Answer: B. Temperature of the mix
Rationale: Asphalt becomes more workable at higher temperatures,
allowing proper placement and compaction.
4. What is the main function of a tack coat?
A. To color the pavement
B. To bind asphalt layers together
C. To cool the surface
D. To increase thickness
Correct Answer: B. To bind asphalt layers together
Rationale: A tack coat ensures adhesion between existing and new
asphalt layers, preventing slippage.
5. What happens if asphalt is placed at too low a temperature?
A. Improved compaction
B. Better bonding
C. Poor compaction and weak pavement
D. Faster curing
Correct Answer: C. Poor compaction and weak pavement
Rationale: Cold asphalt stiffens quickly, making it difficult to compact
properly and reducing durability.
6. What is segregation in asphalt paving?
A. Uniform mix distribution
B. Separation of coarse and fine particles
C. Overheating of binder
D. Excess moisture in base
Correct Answer: B. Separation of coarse and fine particles
Rationale: Segregation leads to inconsistent pavement quality and
weak spots in the surface.
7. What is the purpose of a prime coat?
A. To paint the surface
B. To waterproof the subgrade
C. To bind asphalt layers
D. To cool aggregates
Correct Answer: B. To waterproof the subgrade
Rationale: A prime coat penetrates and stabilizes the base layer,
reducing moisture infiltration.
, 8. Which tool is used to measure asphalt temperature?
A. Barometer
B. Thermometer
C. Hydrometer
D. Altimeter
Correct Answer: B. Thermometer
Rationale: A thermometer ensures asphalt is within proper
temperature range for placement and compaction.
9. What is the typical function of a paver machine?
A. To crush aggregates
B. To transport asphalt only
C. To place and distribute asphalt evenly
D. To cool asphalt
Correct Answer: C. To place and distribute asphalt evenly
Rationale: The paver spreads asphalt uniformly before compaction
by rollers.
10. What is rutting in asphalt pavements?
A. Surface cracking due to shrinkage
B. Depression in wheel paths
C. Surface polishing
D. Binder bleeding
Correct Answer: B. Depression in wheel paths
Rationale: Rutting occurs when pavement deforms under repeated
traffic loads.
11. What is the role of a steel wheel roller?
A. Crushing aggregate
B. Finishing and compacting asphalt surface
C. Mixing asphalt
D. Heating asphalt
Correct Answer: B. Finishing and compacting asphalt surface
Rationale: Steel wheel rollers provide smooth finish and initial
compaction of asphalt layers.
12. What is asphalt bleeding?
A. Loss of aggregate
B. Excess binder on surface
