Such non-directional vibration with unadjustable amplitude has a tendency to lift the surface material, and with the progress of compaction, the reflection and 'bounce' of the vibration wave on the compacted material layer can lead to the vibration of the surface layer of the paving material, the crushing of the aggregate of the surface layer and other construction defects.

[0005] To solve one of the above problems, a novel road roller adjustable amplitude vibration steel wheel is urgently needed. CONTENT OF THE UTILITY MODEL
