The tandem steel wheel roller is a compaction machine with steel rollers front and rear. Its core feature is “dual steel wheels + vibration function” — both wheels are rigid steel, usually with adjustable vibration systems (adjustable amplitude and frequency). It achieves high-intensity compaction of pavement materials through the rigid pressure of steel wheels and impact from vibration.

It is a core device in asphalt pavement construction, mainly used in the initial compaction stage (following pavers to quickly compact high-temperature asphalt mixtures for shaping, reducing difficulties from temperature drop) and recompaction stage (enhancing density via high-frequency vibration). It also works for compacting gravel bases, cement-stabilized layers, etc.

Core advantages:
– Strong, rigid compaction capacity, suitable for high-intensity density needs;
– Adjustable vibration parameters, adapting to different thicknesses and materials;
– Synchronized dual-wheel rolling, easy to control pavement flatness.
