The pneumatic tired roller is a key piece of equipment specially responsible for final rolling, sealing and finishing in asphalt pavement construction, forming an ideal combination with the tandem-drum roller.

I. Main Functions

Final Rolling and Finishing

Performs the final leveling and compaction after the vibratory compaction by the tandem-drum roller.Eliminates wheel marks to make the pavement smoother and more aesthetically pleasing.

Kneading Compaction (Core Function)

The rubber tires provide flexible compaction, exerting a kneading effect on the asphalt mixture.This rearranges and interlocks the aggregates, improving density and reducing micro-cracks.

Sealing Surface Voids

The uniform pressure from the rubber tires squeezes asphalt mortar to the surface.It forms a dense, waterproof surface course, enhancing the durability and impermeability of the pavement.

Improving Surface Smoothness and Gloss

After compaction, the pavement has a better oil appearance and higher gloss, resulting in improved visual quality.

II. One-Sentence Summary

• Tandem-drum roller: Responsible for vibratory compaction to ensure density.

• Pneumatic tired roller: Responsible for kneading, void sealing, finishing and leveling.

Standard asphalt pavement construction process:Initial rolling (tandem-drum roller) → Secondary rolling (tandem-drum roller) → Final rolling (pneumatic tired roller)
