1. During asphalt mix production, what is the primary purpose of
heating aggregates before mixing them with asphalt binder?
A. To increase aggregate weight
B. To remove moisture and ensure proper binder coating
C. To reduce binder viscosity permanently
D. To improve aggregate color
Answer: B. To remove moisture and ensure proper binder coating
Rationale: Moisture prevents proper adhesion between asphalt binder
and aggregate. Heating dries the aggregate and raises its temperature
so the binder can uniformly coat all particles, producing a durable
asphalt mixture.
2. Which asphalt binder performance grade (PG) system primarily
classifies binders based on what criterion?
A. Aggregate source
B. Climatic performance temperatures
C. Asphalt plant size
D. Pavement thickness
Answer: B. Climatic performance temperatures
1
,Rationale: The Superpave Performance Grade (PG) system classifies
asphalt binders according to expected high and low pavement service
temperatures, ensuring appropriate performance under local climate
conditions.
3. Excessive asphalt binder in a hot mix asphalt (HMA) typically
results in which pavement distress?
A. Ravelling
B. Bleeding
C. Thermal cracking
D. Aggregate polishing
Answer: B. Bleeding
Rationale: Too much asphalt binder fills air voids and migrates to the
pavement surface during hot weather, creating a shiny, slippery
surface known as bleeding or flushing.
4. What is the primary function of mineral filler in asphalt mixtures?
A. Replace coarse aggregate
B. Improve binder stiffness and fill microscopic voids
C. Lower aggregate friction
D. Reduce pavement density
Answer: B. Improve binder stiffness and fill microscopic voids
Rationale: Mineral filler fills very fine voids within the aggregate
structure and interacts with asphalt binder to improve stiffness,
stability, and durability.

, 5. Which laboratory test primarily determines the resistance of
compacted asphalt mixtures to deformation?
A. Sand Equivalent Test
B. Marshall Stability Test
C. Los Angeles Abrasion Test
D. Atterberg Limits Test
Answer: B. Marshall Stability Test
Rationale: The Marshall Stability Test evaluates the maximum load an
asphalt specimen can withstand before failure, providing an indication
of rutting resistance and structural strength.
6. During paving, what is the recommended practice if segregation is
observed behind the paver?
A. Add water immediately
B. Ignore minor segregation
C. Correct material flow and placement immediately
D. Increase paving speed significantly
Answer: C. Correct material flow and placement immediately
Rationale: Segregation creates weak areas susceptible to moisture
infiltration and premature failure. Immediate corrective action
minimizes long-term pavement defects.
7. Which aggregate property most directly affects skid resistance?
A. Particle color
B. Surface texture and angularity
C. Moisture content
D. Density alone
3
, Answer: B. Surface texture and angularity
Rationale: Angular, rough-textured aggregates maintain friction and
improve vehicle traction throughout pavement service life.
8. Why are air voids intentionally maintained within asphalt
mixtures?
A. To increase water absorption
B. To allow slight binder expansion and reduce bleeding
C. To reduce aggregate interlock
D. To decrease pavement life
Answer: B. To allow slight binder expansion and reduce bleeding
Rationale: Proper air void content allows thermal expansion of
asphalt binder while minimizing rutting and bleeding without
compromising durability.
9. Which distress is characterized by progressive loss of aggregate
particles from the pavement surface?
A. Rutting
B. Ravelling
C. Reflection cracking
D. Shoving
Answer: B. Ravelling
Rationale: Ravelling occurs when asphalt binder deteriorates or loses
adhesion, allowing aggregate particles to detach from the pavement
surface.
