1. What is the primary purpose of asphalt binder in asphalt concrete?
A. To provide aggregate strength
B. To fill air voids
C. To bind aggregates together
D. To reduce traffic load
Correct Answer: C
Rationale: Asphalt binder acts as the glue that holds aggregate
particles together in the asphalt mixture.
2. Which material makes up the largest percentage by weight in asphalt
concrete?
A. Asphalt binder
, B. Mineral filler
C. Additives
D. Aggregates
Correct Answer: D
Rationale: Aggregates typically constitute 90–95% of the total
asphalt mix by weight.
3. What test is commonly used to determine asphalt binder consistency
at high temperatures?
A. Penetration test
B. Ductility test
C. Viscosity test
D. Flash point test
Correct Answer: C
Rationale: Viscosity testing evaluates how asphalt binder flows at
elevated temperatures.
4. The purpose of mineral filler in an asphalt mix is to:
A. Increase asphalt content
B. Improve drainage
C. Fill voids and stiffen the mix
D. Reduce mixing temperature
Correct Answer: C
Rationale: Mineral filler improves stability by filling voids and
stiffening the asphalt mastic.
,5. What does HMA stand for?
A. Heavy Mineral Aggregate
B. Hot Mix Asphalt
C. Hot Mix Asphalt
D. High Modulus Asphalt
Correct Answer: C
Rationale: HMA is the standard abbreviation for Hot Mix Asphalt.
6. Which temperature range is typical for placing Hot Mix Asphalt?
A. 50–70°C
B. 80–100°C
C. 120–160°C
D. 180–220°C
Correct Answer: C
Rationale: HMA must be placed hot enough to ensure workability
and compaction.
7. What property of asphalt binder helps resist cracking at low
temperatures?
A. Hardness
B. Flexibility
C. Viscosity
D. Adhesion
Correct Answer: B
, Rationale: Flexibility allows the binder to accommodate thermal
contraction without cracking.
8. Which test evaluates the resistance of asphalt mix to moisture
damage?
A. Marshall Stability test
B. Tensile Strength Ratio (TSR)
C. Penetration test
D. Sieve analysis
Correct Answer: B
Rationale: TSR compares strength of conditioned and unconditioned
samples to assess moisture susceptibility.
9. The primary function of compaction in asphalt paving is to:
A. Improve appearance
B. Increase temperature
C. Reduce air voids and increase density
D. Speed up cooling
Correct Answer: C
Rationale: Proper compaction ensures durability by reducing
permeability and improving load distribution.
10. Excessive air voids in asphalt pavement can lead to:
A. Higher stability
B. Improved drainage
C. Premature oxidation and cracking
