Florida Asphalt Paving Contractor Exam Questions And Correct Answers (Verified Answers) Plus Rationale2026 Q&A| Instant Download Pdf

• What is the primary binder used in asphalt paving mixes?
• Portland cement
• Lime
• Asphalt cement
• Fly ash

Rationale: Asphalt cement is the standard binder used in asphalt paving

mixes due to its adhesion and durability.

• The Florida DOT typically specifies asphalt using which grading

system?

• Viscosity grade
• Performance grade (PG)
• Aggregate gradation
• Marshall grade

Rationale: FDOT uses the Performance Grade (PG) asphalt binder system

based on environmental conditions.

• PG 67-22 indicates asphalt designed for what temperature range?
• High 60°C, low –22°C
• High 67°C, low –22°C
• High 67°F, low –22°F
• High 22°C, low 67°C

Rationale: PG grades express high- and low-temperature performance

parameters. 1 / 3

• Which test evaluates asphalt binder stiffness at low temperatures?
• Marshall stability
• Bending beam rheometer (BBR)
• Gyratory compaction test
• Rice test

Rationale: BBR measures low-temperature stiffness to prevent cracking.

• What is the main purpose of tack coat?
• Waterproof surface
• Ensure bond between pavement layers
• Strengthen base
• Reduce aggregate absorption

Rationale: Tack coat creates adhesion between existing and new layers.

• Which material is commonly used as tack coat?
• Cutback asphalt
• Asphalt emulsion
• Polymer pellets
• Cement slurry

Rationale: Emulsions are safer, cleaner, and preferred over cutbacks.

• Which aggregate property is most important for skid resistance?
• Moisture content
• Angularity
• Microtexture and polish resistance
• Absorption

Rationale: Surface texture determines skid resistance.

• What does RAP stand for?
• Rapid Asphalt Paving
• Residual Aggregate Product
• Reclaimed Asphalt Pavement
• Reinforced Asphalt Product

Rationale: RAP is milled or processed recycled asphalt mixture. 2 / 3

• The maximum allowable air voids for a standard FDOT dense-graded

asphalt mix is typically:

A. 10–12%

B. 6–8%

C. 3–5%

D. 1–2%

Rationale: Dense-graded mixes require low voids to maintain durability.

• What is the purpose of the Rice test?
• Determine binder content
• Determine theoretical maximum specific gravity (Gmm)
• Measure compaction level
• Test aggregate wear

Rationale: Gmm is determined by the Rice test for calculating air voids.

• The Florida DOT requires which compaction equipment for final

rolling?

• Pneumatic roller
• Steel-wheeled static roller
• Vibratory or static steel drum roller
• Plate compactor

Rationale: Steel drum rollers provide smooth finish and density.

12. The term "lift" refers to:

• The crane needed on site
• Thickness of one asphalt layer
• Slope of the pavement
• Air void percentage

Rationale: A lift is a single compacted layer of asphalt.

• What is the typical temperature for compacting hot-mix asphalt?
• / 3
