1. What is the primary objective of Level 2 Asphalt Technician testing
procedures?
A. To ensure project cost savings
B. To verify pavement aesthetics
C. To ensure materials and compaction meet specifications
D. To increase paving speed
Answer: C
Rationale: Level 2 responsibilities focus on quality control, ensuring
mix properties and compaction comply with job specifications.
2. Which test is commonly used to determine asphalt binder
performance grade?
, A. Marshall Stability
B. Superpave PG grading system
C. Sand equivalent test
D. Sieve analysis test
Answer: B
Rationale: The Superpave system grades asphalt binders based on
climate performance characteristics.
3. The maximum theoretical specific gravity (Gmm) is determined using:
A. Core density test
B. Rice test
C. Marshall hammer test
D. Ignition oven test
Answer: B
Rationale: Gmm is obtained from the Rice test which measures the
density of asphalt mix without air voids.
4. Air voids in asphalt mixtures are calculated using:
A. Gmm and Gmb
B. Penetration and viscosity
C. Film thickness
D. Sieve distribution
Answer: A
Rationale: Air voids = (Gmm - Gmb)/Gmm × 100.
,5. The Gmb value refers to:
A. Maximum theoretical density
B. Binder viscosity
C. Bulk specific gravity of compacted mixture
D. Gradation uniformity
Answer: C
Rationale: Gmb measures density including air voids in compacted
mix.
6. Which piece of equipment is used to check mat density during paving?
A. Straightedge
B. Penetrometer
C. Nuclear gauge
D. Smoothness profiler
Answer: C
Rationale: Nuclear gauges measure in-place density
nondestructively.
7. During paving, roller patterns are used to:
A. Reduce binder content
B. Ensure uniform compaction
C. Change aggregate gradation
D. Change mix temperature
Answer: B
, Rationale: Roller patterns ensure consistent compaction across the
mat.
8. A high air void content in compacted asphalt generally indicates:
A. Excess binder
B. Good durability
C. Insufficient compaction
D. Proper rolling
Answer: C
Rationale: Higher air voids mean density is too low, reducing
durability.
9. The ignition oven test is primarily used to:
A. Determine binder viscosity
B. Measure aggregate specific gravity
C. Determine asphalt binder content
D. Measure temperature of mix
Answer: C
Rationale: The ignition oven burns off binder to calculate binder
percentage.
10. Segregation in asphalt pavement is usually caused by:
A. Excess asphalt binder
B. Improper handling or loading of mix
C. Low road temperature
D. Too many rollers
