The core compaction advantages of pneumatic-tired rollers lie in their flexible rolling and uniform compaction. They can achieve deep-layer compaction without damaging the material structure, making them particularly suitable for scenarios requiring high compaction degrees both on the surface and inside the material.

1. Flexible Compaction to Protect Material Structure

The tires come into contact with materials through their own elastic deformation, rather than rigid extrusion.

• It avoids the crushing of material particles, making it especially suitable for brittle materials such as graded crushed stone and rock-filled subgrades. This helps maintain the original gradation of the materials and improves overall load-bearing capacity.

• During the rolling process, it will not form a hard crust on the material surface, preventing the problem of "surface compaction while internal looseness" and ensuring consistent compaction from the surface layer to the deep layer.

2. Uniform Pressure Distribution for Higher Compaction Degree

The contact between the tires and the ground is surface contact, and the ground contact specific pressure can be flexibly adjusted by increasing or decreasing counterweights.

• The ground contact pressure is evenly distributed without obvious rolling marks, which can effectively eliminate internal pores of the material and improve the overall compaction degree.

• Combined with the kneading effect of the tires, it can further enhance the interlocking force between material particles and reduce the risk of subsequent settlement. It is particularly suitable for the final compaction process of asphalt pavements.

3. Wide Adaptability to Various Materials and Strong Versatility

Compared with steel-wheel rollers, pneumatic-tired rollers have wider adaptability to different material types.

• They can be used for compaction of various materials such as asphalt pavements (especially the final compaction of modified asphalt and rubberized asphalt pavements), graded crushed stone, stabilized soil, and rock-filled subgrades.

• They can not only meet the compaction needs of road bases and subbases but also be used for the final compaction of asphalt surface layers, catering to the operation requirements of different engineering stages.

4. Improved Surface Flatness and Impermeability

The flexible rolling and kneading effects of the tires can finely trim the material surface.

• It can effectively make up for the slight unevenness that may occur after steel-wheel rolling, improving the surface flatness of pavements or sites.

• For asphalt pavements, it can further close the tiny pores on the surface layer, enhance the impermeability and durability of the pavement, and reduce the damage to the base layer caused by rainwater penetration.
