  1. Which petrographic feature in coarse aggregate is most directly associated with accelerated alkali-silica reaction (ASR) susceptibility? β†’ Strained quartz and microcrystalline silica
  2. What does "Air Content" refer to in concrete testing, according to CCIL? β†’ The volume of air voids in plastic concrete, excluding pores in aggregate particles
  3. When capping concrete cylinders with sulfur mortar per ASTM C617, the cap thickness should not exceed: β†’ 6 mm
  4. What does the term 'percent compaction' mean in the context of HMA field testing? β†’ The ratio of field density to maximum theoretical density, expressed as a percentage
  5. According to ASTM D422, what is the standard sieve size used to separate coarse and fine fractions during a mechanical sieve analysis of soil? β†’ No. 4 (4.75 mm)
  6. Which action is necessary when a sample contains aggregate larger than what is appropriate for the size of the moulds or equipment? β†’ Sieve the sample to remove larger aggregates
  7. What does a bleeding rate in fresh concrete primarily indicate? β†’ Excess mix water migrating to the surface
  8. A laboratory balance is found to read 0.05 g high across its entire range. This type of error is called: β†’ Systematic error
  9. Which ASTM standard governs the determination of flash and fire points of bituminous materials using the Cleveland Open Cup method? β†’ ASTM D92
  10. What is the purpose of a longitudinal joint in asphalt pavement construction? β†’ To connect adjacent lanes paved in separate passes while maintaining density at the seam
  11. The hierarchy of controls in laboratory safety lists which measure as MOST effective at reducing hazard exposure? β†’ Elimination or substitution
  12. At what test temperature is Marshall Stability typically determined, and why? β†’ 60Β°C, to simulate maximum summer pavement surface temperature
  13. Which test method is used to measure the elongation index of coarse aggregate according to Canadian standards? β†’ CSA A23.2-13A
  14. A spectrophotometer's wavelength accuracy is verified using: β†’ Holmium oxide or didymium glass filters with known absorption peaks
  15. When sampling plastic concrete, which method is recommended? β†’ Passing a receptacle completely through a discharge stream
  16. What pavement condition survey method assigns a numerical rating from 0 to 100 to quantify overall pavement surface condition? β†’ Pavement Condition Index (PCI) per ASTM D6433
  17. Where should cementing materials be stored? β†’ In a dry place, in moisture-proof containers
  18. According to CSA A23.2-5C, when performing a slump test, how should the slump cone be lifted from the concrete sample? β†’ Vertically, in a smooth and continuous motion taking approximately 5 seconds
  19. When are laboratory workers required to remove personal protective equipment (PPE) such as gloves before leaving the lab? β†’ Before exiting into any common area or corridor
  20. In the Bending Beam Rheometer (BBR) test, which two parameters are measured to evaluate low-temperature cracking resistance? β†’ Creep stiffness (S) and m-value
  21. What is a typical minimum percent compaction specification for HMA pavements? β†’ 92–96%
  22. Which specification document governs the performance grading (PG) of asphalt binders used in pavement construction across North America? β†’ AASHTO M 320
  23. During DSR testing of a PAV-aged binder for fatigue cracking evaluation, which criterion must be satisfied? β†’ G*Γ—sinΞ΄ ≀ 5,000 kPa
  24. Which class of fire extinguisher is appropriate for a laboratory fire involving electrical equipment? β†’ Class C
  25. Environmental conditions such as temperature and humidity must be monitored and recorded during calibration because: β†’ They influence measurement results and form part of the uncertainty budget
  26. What is the concrete maturity method used to estimate? β†’ The in-place strength of concrete based on its time-temperature history during curing
  27. ISO/IEC 17025 requires that calibration laboratories demonstrate competence through: β†’ Proficiency testing and interlaboratory comparisons
  28. When casting 3 cylinders measuring 100mm x 200mm, what is the minimum sample size required? β†’ 20 liters
  29. What is the minimum air void content typically specified for compacted hot mix asphalt pavement lifts to ensure adequate durability? β†’ 3%
  30. What is the purpose of the meniscus correction applied when reading a hydrometer during a particle-size analysis? β†’ To account for the curved water surface at the hydrometer stem

What Practice Test Geeks adds beyond an AI chat for CCIL

An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:

  • A timed, full-length CCIL mock exam β€” 80 questions in 120 minutes with a 75% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
  • A fixed CCIL question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
  • Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
  • CCIL flashcards built from the same question bank.
  • Free CCIL practice tests with the correct answer shown after each question.
