1. What is the primary purpose of a seal coat on an
existing asphalt pavement?
A. Increase the structural thickness of the pavement
B. Protect the pavement from oxidation and water
infiltration
C. Replace failed base material
D. Eliminate all pavement cracking
Answer: Protect the pavement from oxidation and water
infiltration
Rationale: A seal coat protects an existing asphalt
surface from air, moisture, oxidation, and environmental
deterioration while also improving surface
characteristics and extending pavement service life.
2. Which aggregate characteristic is generally desirable
for a chip seal?
A. Smooth and rounded particles
B. Highly absorptive clay particles
C. Clean, durable, angular aggregate
D. Organic soil particles
Answer: Clean, durable, angular aggregate
,Rationale: Clean, durable, angular aggregate provides
good interlock, skid resistance, and retention in the
asphalt binder.
3. Which piece of equipment is primarily used to apply
liquid asphalt uniformly?
A. Motor grader
B. Asphalt paver
C. Distributor truck
D. Backhoe
Answer: Distributor truck
Rationale: The distributor truck uses a spray bar and
controlled pumping system to apply asphalt binder at a
specified rate and uniform width.
4. What is one of the most important steps before
applying a seal coat?
A. Flooding the pavement with water
B. Cleaning the pavement of dust, dirt, and loose
material
C. Applying loose sand everywhere
D. Increasing traffic on the pavement
Answer: Cleaning the pavement of dust, dirt, and loose
material
Rationale: Dust and loose debris interfere with adhesion
between the asphalt binder and existing pavement,
increasing the possibility of premature failure.
5. What is a major concern when applying a seal coat to
a wet pavement?
A. Excessive aggregate interlock
B. Increased skid resistance
,C. Poor adhesion and improper curing
D. Faster pavement strengthening
Answer: Poor adhesion and improper curing
Rationale: Excess moisture can interfere with the bond
between the binder and pavement and can delay or
disrupt the breaking and curing of emulsified asphalt.
6. What is the function of an asphalt distributor's spray
bar?
A. Compact aggregate
B. Remove pavement markings
C. Apply asphalt binder uniformly across the pavement
D. Heat aggregate
Answer: Apply asphalt binder uniformly across the
pavement
Rationale: The spray bar distributes the binder through
multiple nozzles to produce the specified application
rate and uniform coverage.
7. What does "flushing" or "bleeding" generally
indicate?
A. Too little asphalt binder
B. Excessive aggregate loss
C. Excess asphalt binder at the pavement surface
D. Excessive pavement cracking
Answer: Excess asphalt binder at the pavement surface
Rationale: Flushing occurs when excessive binder rises
to the surface, reducing texture and potentially
reducing skid resistance.
8. What is raveling?
, A. Excessive asphalt on the surface
B. Loss of aggregate particles from the pavement
surface
C. Expansion of concrete
D. Movement of a pavement joint
Answer: Loss of aggregate particles from the pavement
surface
Rationale: Raveling is the progressive loss of aggregate
caused by inadequate bonding, aging, insufficient
binder, poor aggregate cleanliness, or other pavement
deficiencies.
9. What is a fog seal?
A. A thick asphalt overlay
B. A concrete curing compound
C. A light application of diluted asphalt emulsion used to
seal and rejuvenate a pavement surface
D. A layer of aggregate placed before paving
Answer: A light application of diluted asphalt emulsion
used to seal and rejuvenate a pavement surface
Rationale: A fog seal can reduce surface permeability,
bind lightly raveled material, and rejuvenate an
oxidized asphalt surface when appropriate.
10. Why is aggregate gradation important in seal-coat
work?
A. It determines the color of the pavement
B. It determines the truck's fuel consumption
C. It affects coverage, texture, voids, and binder
requirements
D. It eliminates the need for rolling
Answer: It affects coverage, texture, voids, and binder
requirements
