INTRODUCTION
The NICET Level 3 Highway Construction Inspection
assessment evaluates the advanced knowledge and
supervisory judgment required for senior-level inspection of
highway construction projects. It assesses interpretation of
plans and specifications, soil and slope stabilization, roadway
and structure construction, concrete pavement, materials
testing, quality control and quality assurance, and project
administration. Items include multiple-choice and scenario-
based questions requiring critical thinking and real-world
application. The examination emphasizes AASHTO and ASTM
standards, OSHA compliance, and professional accountability
essential for NICET certification. This assessment prepares
candidates for supervisory inspection roles on capital highway
construction projects.
SECTION ONE: QUESTIONS 1–100
Question 1
A Level III inspector is reviewing the compaction results for a
roadway embankment. The field density test indicates 92%
of maximum dry density per AASHTO T 180, but the
,specifications require 95%. Which action should the
inspector take first?
A. Accept the lift because 92% is within acceptable tolerance
B. Direct the contractor to rework the lift with additional
compaction and moisture adjustment
C. Document the result and continue placement of the next
lift
D. Notify the project engineer that the test result is invalid
🟢 Correct answer: B
🔴 RATIONALE: The compaction result does not meet the
specification requirement of 95%. The inspector must direct
the contractor to rework the lift by adding moisture and
recompacting until the required density is achieved.
Accepting deficient work would compromise the long-term
performance of the pavement structure.
Question 2
During inspection of a mechanically stabilized earth (MSE)
wall, the inspector observes that the geogrid reinforcement
is being placed with insufficient overlap at the panel joints.
Which action should the inspector take?
A. Approve the installation because overlap is not critical for
MSE walls
, B. Stop work and require the contractor to correct the
overlap per the approved shop drawings and specifications
C. Document the observation and continue inspection
D. Allow the contractor to proceed if the wall height is less
than 10 feet
🟢 Correct answer: B
🔴 RATIONALE: Geogrid overlap at panel joints is a critical
design element for MSE wall stability. Insufficient overlap
can lead to wall failure. The inspector must stop work and
require correction in accordance with the approved shop
drawings and project specifications.
Question 3
A Level III inspector is supervising a team inspecting hot mix
asphalt (HMA) paving. The contractor's rolling pattern
appears inadequate, and the mat shows signs of insufficient
density. Which test method should the inspector reference
to evaluate in-place density?
A. AASHTO T 245
B. AASHTO T 166
C. AASHTO T 310
D. AASHTO T 283
🟢 Correct answer: B
