Rollers generally rely on their own weight to compact the soil through vibration. When the roller is running, the wheels or rollers will apply pressure to the surface of the soil or road surface material, gradually reducing the gap between the soil or material particles, thereby increasing the density of the soil or material. It is mainly used for compaction operations on roads, airports, parking lots and other sites to ensure the flatness and durability of the road surface.

With its high compaction efficiency, strong adaptability, easy operation, compact structure and convenient maintenance, the roller has significant advantages in improving construction quality, reducing costs, broadening application scope and improving construction efficiency. These advantages and characteristics make the roller play an important role in various road construction and maintenance projects.
