Dynapac Road Roller technology greatly enhances bridge deck construction, preventing aggregate breakage, reducing noise by 50%, achieving zero complaints during nighttime construction, reducing the number of compaction passes by 30% compared to competitors, and shortening the construction period for the same road section.

Vibratory Compaction Technology:

Dynapac pioneered vibratory roller technology, a global leader in this field.

Precisely adjustable vibration frequency (25–67Hz) to adapt to different materials.

Dual amplitude options (high/low) to adapt to different layer thicknesses.

The vibration system uses an eccentric block design for uniform and stable vibration force.

Vibration bearings are from top-tier SKF/FAG brands, ensuring extremely long service life.

Vibratory compaction efficiency is 40–60% higher than static compaction. Fewer passes are required for the same compaction effect, significantly saving fuel and time.

Precise Compaction Control:

Vibration Frequency

1. Precisely adjustable amplitude, adaptable to any compaction material

2. Automatic Vibration Cut-off System (AVS): Automatically stops vibration during turns to prevent over-compaction

3. Edge compaction function: ensures consistent compaction at roadside corners with the center

4. Compaction pass counter: ensures no compaction is missed in each pass

5. Industry-leading compaction uniformity, significantly extending pavement life

Oscillation compaction technology:

6. Horizontal oscillation replaces vertical vibration

7. No upward impact on asphalt surface layer, no aggregate displacement or breakage

8. Suitable for compacting sensitive areas such as bridge decks and thin asphalt layers

9. Oscillation compaction noise is 50% lower than vibration compaction, allowing for unimpeded construction at night in urban areas

10. No damage to concrete bridge decks, the preferred technology for bridge deck construction
