Which aspect does the pavement smoothness rideability address?

Pavement smoothness rideability primarily addresses driver comfort. A smooth surface enhances the overall driving experience by reducing vibrations and jolting, leading to a more pleasant journey. When a road is well-maintained and smooth, it also contributes to better vehicle handling and can minimize fatigue for drivers, making travel safer and more enjoyable.

While structural integrity is crucial for the longevity and strength of a pavement, it does not directly relate to how smooth or comfortable the ride is. Similarly, surface texture and material durability play roles in other performance aspects, but they don't specifically focus on the smoothness or rideability that affects the comfort of drivers. Thus, the emphasis on driver comfort accurately captures the essence of what pavement smoothness rideability is intended to assess.
