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
  • procedures?

  • To ensure project cost savings
  • To verify pavement aesthetics
  • To ensure materials and compaction meet specifications
  • To increase paving speed

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
  • / 4
