IntroductionThe purpose of the Kentucky Quality Control Technician Exam is to verify the technical
competency of professionals performing field and laboratory materials testing on transportation
infrastructure projects within the Commonwealth. This comprehensive assessment evaluates
fundamental engineering concepts, regulatory compliance, and practical field application skills required
to satisfy Kentucky Transportation Cabinet (KYTC) quality assurance standards. Featuring both
foundational multiple-choice and practical scenario-based problems, the examination challenges
technicians to apply critical thinking and data analysis to real-world highway construction scenarios.
Technicians must demonstrate proficiency in interpreting technical specifications, performing rigorous
volumetric calculations, and maintaining strict adherence to ethical and safety protocols to ensure
materials meet project lifespans.
, SECTION ONE: QUESTIONS 1–100
A technician is obtaining a field sample of coarse aggregate from a stockpile for gradation analysis.
According to standard quality control procedures, which method must be utilized to minimize
segregation?
A. Shoveling materials directly from the outer perimeter base of the pile.
B. Combining increments taken from the top third, middle third, and bottom third of the pile using a
sampling tube or shield.
C. Taking one large batch from the exact peak of the stockpile where fine particles aggregate.
D. Scraping material exclusively from the surface crust of the pile.
🟢 B. Combining increments taken from the top third, middle third, and bottom third of the pile using a
sampling tube or shield.
🔴 RATIONALE: To ensure a representative sample of coarse aggregate from a stockpile, increments
must be taken from multiple zones (top, middle, and bottom thirds) with the outer layer discarded or
shielded to prevent segregated material from biasing the test results.
During a fresh concrete field verification test on a KYTC bridge deck pour, the technician observes
a slump that exceeds the maximum allowable specification limit. What is the immediate correct
action required?
A. Proceed with casting the strength cylinders and note the deviation on the delivery ticket.
B. Add additional coarse aggregate directly into the mixer truck drum to stiffen the mix.
C. Reject the load immediately and notify both the project engineer and the plant quality control
manager.
D. Allow the truck to sit for 30 minutes so the concrete can lose workability naturally before testing again.
🟢 C. Reject the load immediately and notify both the project engineer and the plant quality control
manager.
🔴 RATIONALE: Materials failing to meet the strict fresh property envelope limits, such as excessive
slump, must be rejected prior to placement to avoid structurally deficient concrete, followed by immediate
notification to stakeholders.
