1. During an asphalt paving operation, the inspector observes that
the contractor has begun placing asphalt concrete even though the
required certified asphalt-concrete plant technician is not present at
the plant or job site. What is the most appropriate inspection
response?
A. Allow production to continue because the paving inspector is
responsible for quality assurance.
B. Allow production to continue provided the mixture temperature is
within the specified range.
C. Require the contractor to comply with the applicable certification
requirement before continuing operations.
D. Allow production for one hour while waiting for the technician to
arrive.
Answer: C.
Rationale: DOTD's asphalt QA documentation identifies the presence
of appropriately certified personnel as an important component of the
quality system. For asphalt concrete production, the contractor is
required to employ an appropriately certified Asphalt Concrete Plant
Technician, with the applicable manual stating that daily plant
operations should not commence unless the certified technician is
1
,present. The paving inspector should therefore recognize the
personnel-certification deficiency rather than treating temperature
alone as sufficient evidence of compliance.
2. What is the primary responsibility of an Asphaltic Concrete
Paving Inspector under the DOTD certification framework?
A. Design all asphalt mixtures used on the project.
B. Perform complete inspection and acceptance of asphalt-concrete
paving operations.
C. Operate the contractor's asphalt plant laboratory.
D. Establish the contractor's production rates.
Answer: B.
Rationale: DOTD describes Asphaltic Concrete Paving certification as
qualifying inspectors to perform complete inspection and acceptance
on asphalt-concrete paving projects. Plant mix design and plant QC
functions are associated with the asphalt-concrete plant certification
area, so the paving inspector's principal responsibility is field
inspection and acceptance of paving operations rather than taking
over the contractor's production responsibilities.
3. Before asphalt concrete is placed, which item should receive the
inspector's greatest attention?
A. Whether the contractor's equipment is painted in the project color.
B. Whether the underlying surface, alignment, grade, dimensions, and
required preparation comply with the plans and specifications.
C. Whether the haul trucks have identical engine sizes.
D. Whether the contractor has enough employees to finish early.
Answer: B.
2
,Rationale: Asphalt paving quality begins before the mixture reaches
the paver. The inspector must verify that the receiving surface has
been properly prepared and that the required line, grade, width, cross
slope, drainage, cleanliness, and other contract requirements have
been satisfied. Placing an otherwise acceptable mixture on an
improperly prepared surface can still result in a deficient pavement.
4. A truck arrives at the paving site with asphalt mixture that
appears substantially cooler than the mixture from previous loads.
What should the inspector do first?
A. Automatically reject the load solely because it looks different.
B. Ignore the condition because appearance has no significance.
C. Check the applicable specification/project requirements and obtain an
appropriate temperature measurement before deciding disposition.
D. Add water to the mixture to restore workability.
Answer: C.
Rationale: Visual observations are valuable inspection indicators, but
acceptance should be based on documented requirements and
appropriate measurements. Temperature can materially affect
workability, compaction, and ultimately pavement performance. The
inspector should measure and document the condition and compare it
with the governing requirements rather than making an unsupported
rejection or attempting to modify the mixture in the field.
5. What is the principal purpose of controlling the temperature of
hot-mix asphalt during transportation and placement?
A. To increase aggregate particle size.
B. To maintain sufficient workability for proper placement and
compaction without damaging the mixture.
3
, C. To eliminate the need for density testing.
D. To increase the asphalt binder content automatically.
Answer: B.
Rationale: Asphalt mixture must remain workable enough to be placed
and compacted properly. Excessive cooling can make achieving
required density difficult, while excessive heating can adversely affect
binder and mixture properties. Temperature control therefore supports
uniform placement and effective compaction.
6. A paving inspector notices that the paver is repeatedly stopping
and starting because trucks are not arriving consistently. What is
the principal concern?
A. The interruptions may contribute to longitudinal or transverse
irregularities and nonuniform compaction.
B. Stopping the paver always increases asphalt binder content.
C. Stopping has no potential effect on pavement quality.
D. The only concern is the contractor's fuel consumption.
Answer: A.
Rationale: Continuous, properly coordinated paving is important for
producing a uniform mat. Frequent stops can produce changes in
temperature, surface texture, thickness, joint characteristics, and
compaction. The inspector should identify the operational problem
and require the contractor to address the underlying production and
delivery coordination issue.
7. Which paving-machine characteristic is most important when
evaluating whether the paver can produce a uniform mat?
