WAQTC: Asphalt 2 Exam | Questions And
Answers Rated A+ | 2026/2027
1. What are the two primary ingredients in asphalt mixtures?
A. Cement and water
B. Aggregate and asphalt binder
C. Sand and gravel
D. Lime and fly ash
Answer: B
Rationale: Asphalt mixtures consist of two primary ingredients: aggregate (crushed
stone, gravel, sand) and asphalt binder (the glue that holds the mixture together).
2. HMA stands for:
A. Heavy Mix Asphalt
B. Hot Mix Asphalt
C. High Modulus Asphalt
D. Hardened Mix Asphalt
Answer: B
Rationale: HMA stands for Hot Mix Asphalt, which is produced at high temperatures
(typically 275-300°F) to ensure proper coating of aggregate and workability for
placement.
3. WMA stands for:
A. Warm Mix Asphalt
B. Wet Mix Asphalt
C. Wide Mix Asphalt
D. Water Mix Asphalt
,Answer: A
Rationale: WMA stands for Warm Mix Asphalt, which is produced at lower temperatures
than HMA, reducing energy consumption and emissions.
4. What are the three types of asphalt mixtures?
A. Fine, coarse, and medium-graded
B. Dense-graded, open-graded, and gap-graded
C. Hot, warm, and cold
D. Surface, binder, and base
Answer: B
Rationale: The three types of asphalt mixtures are dense-graded (most common,
containing a wide range of particle sizes), open-graded (containing mostly large
particles with few fines), and gap-graded (missing intermediate particle sizes).
5. What is included in the total volume of an asphalt mix?
A. Only aggregate and binder
B. Entrapped air voids, moisture, effective & absorbed binder, and mineral aggregate
C. Only binder and air voids
D. Aggregate, water, and cement
Answer: B
Rationale: The total volume of an asphalt mix includes entrapped air voids, moisture,
effective and absorbed binder, and mineral aggregate.
6. Air Voids (Va) are defined as:
A. The total volume of water in the mix
B. The total volume of small air pockets between coated aggregate particles
C. The volume of asphalt binder in the mix
D. The volume of aggregate in the mix
Answer: B
Rationale: Air voids (Va) are the total volume of small air pockets between coated
aggregate particles in a compacted asphalt mixture.
,7. SMA stands for:
A. Superpave Mix Asphalt
B. Stone Matrix Asphalt
C. Standard Mix Asphalt
D. Surface Mix Asphalt
Answer: B
Rationale: SMA stands for Stone Matrix Asphalt, which is a gap-graded mixture with
high coarse aggregate content and high binder content, providing excellent rut
resistance.
8. Cutback Asphalt is defined as:
A. Asphalt mixed with water
B. Binder that has been modified by blending with a chemical solvent
C. Asphalt that has been heated to high temperatures
D. Recycled asphalt pavement
Answer: B
Rationale: Cutback Asphalt is binder that has been modified by blending with a
chemical solvent to reduce viscosity for lower-temperature applications.
9. Gmm stands for:
A. General mix modulus
B. Theoretical maximum specific gravity
C. Granular mixture measurement
D. Gradation mix method
Answer: B
Rationale: Gmm is the Theoretical Maximum Specific Gravity of an asphalt mixture,
representing the density of the mixture with no air voids (all voids filled with binder). It is
determined by the Rice Test.
, 10. Gmb stands for:
A. General mix binder
B. Measured bulk specific gravity
C. Granular mix base
D. Gradation mix balance
Answer: B
Rationale: Gmb is the Measured Bulk Specific Gravity of a compacted asphalt mixture,
which includes the volume of air voids in the calculation.
11. Gsb stands for:
A. Oven-dry bulk specific gravity of aggregate
B. Saturated surface-dry specific gravity
C. Specific gravity of binder
D. Specific gravity of the mix
Answer: A
Rationale: Gsb is the Oven-Dry Bulk Specific Gravity of aggregate, used to calculate the
volume of aggregate in the mixture.
12. Gsa stands for:
A. Apparent specific gravity of aggregate
B. Asphalt specific gravity
C. Aggregate surface area
D. Air void specific gravity
Answer: A
Rationale: Gsa is the Apparent Specific Gravity of aggregate, which excludes the volume
of water-permeable pores in the aggregate.
13. Gse stands for:
A. Effective specific gravity
B. Estimated specific gravity
