1. During placement of an asphalt concrete surface course, an
inspector observes that the delivered mix temperature is
substantially below the project's specified temperature range. The
paving crew argues that the material can still be compacted
because the ambient temperature is warm. What is the inspector's
BEST response?
A. Allow placement because ambient temperature is more important
than mix temperature
B. Allow placement and require additional roller passes
C. Reject or hold the material in accordance with the project
specifications because inadequate temperature can prevent proper
compaction
D. Add water to the mix to restore workability
Answer: C. Reject or hold the material in accordance with the
project specifications because inadequate temperature can prevent
proper compaction.
Rationale: Asphalt mixtures lose workability as they cool. If the mix
falls outside the specified placement temperature range, adequate
density may become impossible even when additional rolling is
attempted. The inspector should document the condition and enforce
1
,the applicable project requirements rather than permitting an
uncontrolled deviation.
2. A paving inspector is checking a newly placed asphalt mat and
notices that the longitudinal joint between two adjacent lanes
appears open and poorly compacted. Which condition is MOST
likely associated with this problem?
A. Excessive moisture in the aggregate stockpile only
B. Poor joint construction and insufficient compaction at the joint
C. Excessive tack coat application to the centerline
D. Excessive curing time of the asphalt binder
Answer: B. Poor joint construction and insufficient compaction at
the joint.
Rationale: Longitudinal joints are common locations for low density
because the unsupported edge of the first lane can be difficult to
compact and the second lane must be properly overlapped and
compacted. Proper joint construction, adequate overlap, appropriate
roller positioning, and timely compaction are essential.
3. Before asphalt paving begins, the inspector discovers that the
underlying base course contains several soft, pumping areas. What
should the inspector do?
A. Require the paving contractor to place asphalt over the areas
immediately
B. Ignore the areas because asphalt will bridge minor defects
C. Document and report the deficient foundation and require corrective
action according to the project requirements before paving
D. Increase the asphalt lift thickness without approval
2
,Answer: C. Document and report the deficient foundation and
require corrective action according to the project requirements
before paving.
Rationale: Asphalt pavement performance depends heavily on the
stability and uniformity of the underlying layers. Soft or pumping
areas can produce settlement, rutting, cracking, and premature
pavement failure. Paving should not be used as a substitute for
correcting an unacceptable underlying condition.
4. What is the PRIMARY purpose of tack coat between an existing
pavement surface and a new asphalt layer?
A. To increase aggregate size
B. To provide bonding between pavement layers
C. To reduce asphalt binder content
D. To eliminate the need for compaction
Answer: B. To provide bonding between pavement layers.
Rationale: Tack coat promotes adhesion between asphalt layers so they
behave as a composite pavement structure. Without adequate bonding,
slippage, delamination, and premature pavement distress can occur.
5. A contractor applies tack coat heavily enough that significant pools
of asphalt emulsion remain on the pavement surface. What concern
should the inspector have?
A. Excessive tack can create undesirable conditions and should be
addressed according to the specifications
B. More tack always improves pavement performance
C. Excessive tack automatically increases structural capacity
D. Tack coat should always be applied until the pavement appears
completely black and glossy
3
, Answer: A. Excessive tack can create undesirable conditions and
should be addressed according to the specifications.
Rationale: Tack coat is intended to establish a uniform bond, not
create excessive liquid accumulation. Overapplication can cause
tracking, construction problems, or undesirable interlayer behavior.
The inspector should verify application rate and uniformity against the
contract requirements.
6. A truck arrives at the paving site carrying an asphalt mixture.
Which inspection activity is MOST important before the material
is incorporated into the pavement?
A. Determine whether the truck driver's paperwork is handwritten
B. Verify the material identification, delivery information, condition,
and applicable mixture requirements
C. Measure the truck's tire pressure
D. Determine the age of the truck
Answer: B. Verify the material identification, delivery information,
condition, and applicable mixture requirements.
Rationale: Material traceability is critical in quality control. The
inspector should confirm that the delivered mixture corresponds to the
approved job mix or production requirements and should look for
evidence of segregation, contamination, excessive cooling, or other
unacceptable conditions.
7. Why is segregation in an asphalt mixture a serious pavement-
quality concern?
A. It guarantees uniform density
B. It produces areas with different aggregate and binder distributions
that may compact and perform differently
