Ohio Asphalt Technician Level 2 Certification Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2025|2026 Q&A | Instant Download Pdf
- What is the primary objective of Level 2 Asphalt Technician testing
- To ensure project cost savings
- To verify pavement aesthetics
- To ensure materials and compaction meet specifications
- To increase paving speed
procedures?
Answer: C
Rationale: Level 2 responsibilities focus on quality control, ensuring
mix properties and compaction comply with job specifications.
- Which test is commonly used to determine asphalt binder
performance grade? 1 / 4
- Marshall Stability
- Superpave PG grading system
- Sand equivalent test
- 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:
- Core density test
- Rice test
- Marshall hammer test
- 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:
- Gmm and Gmb
- Penetration and viscosity
- Film thickness
- Sieve distribution
Answer: A
Rationale: Air voids = (Gmm - Gmb)/Gmm × 100. 2 / 4
5. The Gmb value refers to:
- Maximum theoretical density
- Binder viscosity
- Bulk specific gravity of compacted mixture
- Gradation uniformity
Answer: C
Rationale: Gmb measures density including air voids in compacted
mix.
- Which piece of equipment is used to check mat density during paving?
- Straightedge
- Penetrometer
- Nuclear gauge
- Smoothness profiler
Answer: C
Rationale: Nuclear gauges measure in-place density
nondestructively.
7. During paving, roller patterns are used to:
- Reduce binder content
- Ensure uniform compaction
- Change aggregate gradation
- Change mix temperature
Answer: B 3 / 4
Rationale: Roller patterns ensure consistent compaction across the
mat.
8. A high air void content in compacted asphalt generally indicates:
- Excess binder
- Good durability
- Insufficient compaction
- Proper rolling
Answer: C
Rationale: Higher air voids mean density is too low, reducing
durability.
9. The ignition oven test is primarily used to:
- Determine binder viscosity
- Measure aggregate specific gravity
- Determine asphalt binder content
- 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:
- Excess asphalt binder
- Improper handling or loading of mix
- Low road temperature
- Too many rollers
