If the pavement is still warm, water, ice, dry ice, or liquid nitrogen may be used to cool the pavement to prevent damage.

• A. Not Applicable
• B. True
• C. Not Stated
• D. False

Answer: (B)

Cooling a pavement that’s still warm helps prevent damage by removing heat before the surface and underlying layers are harmed. When pavement is hot, it can soften, deform, or transfer excessive heat to the base, leading to tracking, rutting, or cracking. Using cooling media such as water, ice, dry ice, or liquid nitrogen provides a way to pull heat away from the surface quickly and control temperature during construction or repair.

Water is commonly used because it’s readily available and effective at cooling. Ice adds cooling with reduced moisture impact, while dry ice and liquid nitrogen offer very rapid, localized cooling when precise temperature control is needed. Each method must be applied carefully to avoid thermal shock, moisture-related issues, or damage from rapid contraction, and to manage runoff and safety.

So, this statement is true because there are practical cooling methods that can protect warm pavement from heat-related damage.
