The term "Wet Weather Performance" in the context of Hot Mix Asphalt (HMA) primarily refers to the ability of the asphalt mixture to resist moisture-induced damage, commonly known as stripping. Stripping occurs when water infiltrates the pavement layer, causing the asphalt binder to lose its adhesion to the aggregate. This process can lead to significant deterioration in pavement performance.

Resisting stripping is crucial for maintaining the integrity of an asphalt pavement, especially in regions subjected to frequent rainfall or wet weather conditions. When the HMA is designed with appropriate materials and additives, it can significantly enhance its wet weather performance, ensuring that the pavement remains durable and functional even under adverse conditions.

In contrast, the other options—susceptibility to damages from rain, effectiveness of compaction, and temperature sensitivity—while relevant to HMA as a whole, do not specifically capture the essence of how an asphalt mixture performs under wet conditions. The focus on moisture-induced damage highlights the importance of ensuring long-lasting pavements that can withstand environmental stresses, making the resistance to stripping the correct interpretation of "Wet Weather Performance."
