What would be the worst choice for rolling hot asphalt?

Using a rubber wheel for rolling hot asphalt is generally considered the least effective choice among the options given. Rubber-tired rollers do offer some benefits, such as the ability to conform to surface irregularities and apply pressure evenly. However, when it comes to compacting hot asphalt, rubber wheels are less effective compared to other roller types.

The key to successful compaction of hot asphalt is to achieve the necessary density and texture while the material is still at the right temperature. Steel wheel rollers, vibratory rollers, and static rollers exert heavier pressure and provide the type of compaction that is optimal for asphalt materials. These types of rollers allow for better distribution of weight and more effective settlement of the asphalt mix, leading to a denser and more durable pavement.

Rubber wheels do not provide the same level of contact pressure or effectiveness in interlocking the aggregate particles in hot asphalt. Therefore, while rubber-tired rollers have their applications, they are not the ideal choice for rolling hot asphalt, as they may fail to achieve the required compaction quality that is essential for long-lasting pavement.
