[0002] With the continuous acceleration of urbanization, the role of municipal road construction has become increasingly prominent, providing a guarantee for urban travel. Roadbed and pavement compaction is an important construction link in municipal road projects. The reasonable application of compaction technology can enhance the stability and durability of the roadbed and pavement. Its construction quality is closely related to the overall project quality. The roller is one of the key components of the road compactor. The design of the roller varies according to different compaction requirements. Traditional rollers are mostly fixed in weight and may have certain limitations in some aspects, such as:

[0003] Limited applicability: Fixed-weight rollers may struggle to adapt to different types of soil or material. For example, overly heavy rollers can lead to overcompaction or machine sinking in soft soils, while insufficient weight can prevent ideal compaction in hard materials. Fixed-weight rollers can also lead to overcompaction in sensitive areas or for special materials, compromising the structural integrity of the material and the final quality of the project.

[0004] Inconvenient adjustment: When facing different compaction requirements, if the weight of the rolling wheel cannot be adjusted, it may be necessary to replace rolling equipment of different weights, which increases the time and cost of construction preparation, increases the complexity of construction operations, and affects construction efficiency.
