What term is used to describe stones expelled from between a truck tire and the pavement?

• A. Loose aggregates
• B. Shot stones
• C. Runoff materials
• D. Airborne debris

Answer: (B)

The term "shot stones" refers specifically to stones that are expelled from the space between a truck tire and the pavement. This occurs as the tire rotates and generates forces that can dislodge small stones that have become trapped in the tread pattern. These stones can then be thrown out onto the road or surrounding area, potentially posing a risk to other vehicles or creating debris on the roadway. Other terms such as "loose aggregates" generally refer to materials used in construction, which can include gravel or stone that is not bound to a surface. "Runoff materials" typically relate to water and substances that flow over land and are not related to tire mechanics. "Airborne debris" describes materials that are lifted off the ground by wind or other forces, which is distinct from the direct expulsion of stones by tire action. Thus, the specificity of "shot stones" in describing this phenomenon makes it the appropriate choice.
