1. What is the primary purpose of asphalt pavement performance
testing?
A. To increase asphalt color
B. To evaluate long-term durability and behavior under traffic and
environmental conditions
C. To reduce aggregate size
D. To eliminate compaction
Answer: B
Rationale: Asphalt performance testing assesses durability, rutting,
cracking, and aging under real-world conditions.
2. Which property is most directly related to rutting resistance?
A. Air voids
B. Binder viscosity
, C. Aggregate gradation stability
D. All of the above
Answer: D
Rationale: Rutting resistance depends on binder stiffness, air voids, and
aggregate structure.
3. What does fatigue cracking in asphalt indicate?
A. Excess binder
B. Repeated traffic loading failure
C. High temperature softening
D. Aggregate polishing
Answer: B
Rationale: Fatigue cracking results from repeated stress cycles under traffic
loads.
4. Which test measures asphalt resistance to permanent deformation?
A. Marshall Stability Test
B. Rutting Test (Hamburg Wheel Tracker)
C. Specific Gravity Test
D. Sieve Analysis
Answer: B
Rationale: Hamburg Wheel Tracker evaluates rutting and moisture
susceptibility.
, 5. What is air void content in asphalt mix?
A. Water trapped in mix
B. Spaces between aggregate particles filled with air
C. Binder content only
D. Dust percentage
Answer: B
Rationale: Air voids are empty spaces affecting durability and compaction.
6. Which factor most influences pavement aging?
A. Traffic volume
B. Oxidation of asphalt binder
C. Aggregate size
D. Mixing time
Answer: B
Rationale: Oxidation hardens the binder leading to cracking.
7. What is the role of asphalt binder?
A. Increase voids
B. Bind aggregate particles together
C. Reduce density
D. Prevent compaction
Answer: B
Rationale: Binder acts as glue holding aggregates in place.
, 8. Which test evaluates moisture damage susceptibility?
A. Los Angeles Abrasion
B. Tensile Strength Ratio (TSR)
C. Sieve Test
D. Ductility Test
Answer: B
Rationale: TSR measures strength loss due to moisture exposure.
9. What does high air void content usually cause?
A. Increased durability
B. Reduced permeability
C. Faster oxidation and cracking
D. Higher density
Answer: C
Rationale: More air voids allow water and air intrusion, accelerating
aging.
10. Which property is MOST important for flexible pavement
performance?
A. Color
B. Flexibility of binder
C. Aggregate shape only
D. Moisture content only
