How is retroreflectivity measured on newly applied markings? A) With a ruler B) By visual inspection C) Using a retroreflectometer D) With a thermometer Answer: C Explanation: Retroreflectometers objectively measure how much light is reflected from the marking. Question 16. What is the primary difference between Type I and Type III glass beads?
Level II Exam
A) Color B) Size and reflectivity C) Weight D) Binder composition Answer: B Explanation: Type III beads are larger and provide higher reflectivity compared to Type I beads. Question 17. Which marking material is most affected by humidity during application? A) Thermoplastic B) Water-based paint C) Polyurea D) Preformed tape Answer: B Explanation: Water-based paints are sensitive to humidity, which can affect drying time and adhesion. Question 18. Which piece of equipment is used to verify pavement marking thickness? A) Caliper gauge
Level II Exam
D) Water-based paint Answer: C Explanation: Epoxy has high abrasion resistance, making it suitable for areas with snow plowing. Question 21. What is the recommended application method for water-based paint? A) Brushing B) Spraying C) Rolling D) Extrusion Answer: B Explanation: Spraying provides an even coat and is efficient for water-based paints. Question 22. Which MUTCD part specifically addresses pavement markings? A) Part 2 B) Part 3 C) Part 4 D) Part 6 Answer: B
