QUESTION 1.
,A contractor requests approval to place structural fill after a prolonged rainfall. Field
density results satisfy the minimum specification, but the inspector observes visible
pumping and rutting beneath construction equipment. What is the most appropriate
action?
A. Reject placement until the underlying material demonstrates adequate stability in
addition to meeting density requirements.
B. Accept the work because density testing governs acceptance.
C. Permit placement if the contractor assumes responsibility for future settlement.
D. Delay only the density testing until moisture conditions improve.
Correct Answer: A. Reject placement until the underlying material
demonstrates adequate stability in addition to meeting density requirements.
Explanation: Density alone does not demonstrate adequate foundation
performance. Visible pumping and rutting indicate unstable support conditions
that may compromise long-term pavement performance. The inspector should
require correction before additional fill is placed. The remaining options improperly
rely on density results or contractor responsibility instead of specification
compliance.

QUESTION 2.
While reviewing concrete placement operations, the inspector notices the contractor
adding water directly into the truck after arrival without documenting the addition.
What should the inspector do first?
A. Allow placement because workability appears acceptable.
B. Verify whether the additional water remains within specification limits and ensure
proper documentation before placement proceeds.
C. Reject every load delivered that day.
D. Ignore the action if slump remains below the maximum limit.
Correct Answer: B. Verify whether the additional water remains within
specification limits and ensure proper documentation before placement
, proceeds.
Explanation: Water may only be added under controlled conditions consistent with
specifications and documented accordingly. The inspector must verify compliance
before concrete is accepted. Automatically rejecting all loads or ignoring
documentation requirements would not represent sound inspection practice.

QUESTION 3.
An inspector discovers that excavation for a drainage structure extends below plan
grade because unsuitable material was encountered. The specifications require
competent bearing material. Which action best reflects proper inspection practice?
A. Order immediate backfilling with available material.
B. Accept the excavation depth because additional depth improves stability.
C. Notify appropriate project personnel, document conditions, and obtain direction
before proceeding with corrective work.
D. Reduce the structure elevation to match the excavation.
Correct Answer: C. Notify appropriate project personnel, document conditions,
and obtain direction before proceeding with corrective work.
Explanation: Changes affecting structural support require documentation and
engineering direction. The inspector should neither redesign the structure nor
independently authorize corrective measures. Proper communication preserves
contractual compliance and structural integrity.

QUESTION 4.
During asphalt paving, mat temperature decreases below specification before final
rolling can be completed. What is the greatest concern?
A. Increased asphalt binder content.
B. Reduced aggregate absorption.
C. Excessive longitudinal joint density.
, D. Failure to achieve required pavement density because compaction becomes
ineffective.
Correct Answer: D. Failure to achieve required pavement density because
compaction becomes ineffective.
Explanation: Asphalt becomes increasingly resistant to compaction as temperature
decreases. Inadequate density significantly reduces pavement durability by
increasing permeability and susceptibility to premature distress. The other options
are not the primary consequence of insufficient rolling temperature.

QUESTION 5.
Which document has the highest priority when resolving a conflict between
construction drawings and written technical requirements, assuming the contract
establishes a standard order of precedence?
A. The governing contract specifications.
B. Shop drawings.
C. Contractor work schedules.
D. Field notebook entries.
Correct Answer: A. The governing contract specifications.
Explanation: Contract documents generally establish an order of precedence, with
written specifications often controlling over drawings for technical requirements.
Shop drawings and schedules cannot override contract requirements without
formal approval. Inspector notes are documentation rather than contract authority.

QUESTION 6.
A nuclear density gauge consistently reports values significantly different from
laboratory correlation data. Before accepting or rejecting production based on those
readings, the inspector should first:
