What are the characteristics of vibratory roller?       

Compared with the static roller, vibratory roller has the following advantages:

1) the vibratory roller with the same quality has better compaction effect than the static roller; the compacted foundation has high compactness and good stability.

2) the production efficiency of vibratory roller is high. When required by the same degree of compaction, compaction times less.

3) due to the application of airborne compaction meter in vibratory roller, the driver can find the weak points in the construction road timely, and take remedial measures at any time, thus greatly reducing the quality of hidden trouble.

4) when compacted asphalt concrete surface, because of vibration, the asphalt material of the surface layer can be fully permeable and flexible with other aggregate. Therefore, the road wear resistance is good, the repair rate is low.

5) compaction of asphalt concrete, allowing the temperature of asphalt concrete is low.

6) can be compacted large size backfill stone static roller compacted material is difficult to.

7) because of the vibration, pressure can work hard cement concrete.

8) when the compaction effect is the same, the vibratory roller is twice lighter than the static roller in the structure quality, and the power of the engine can be reduced by about 30%.

However, due to the vibration of vibratory roller, the environment and the human body have brought some public hazards, which limits the use of vibratory roller. In the densely populated areas, dangerous areas, close to buildings equipped with precision instruments, as well as highway bridge deck, it is not suitable to use vibratory compactor for compaction operation. In addition, because of the influence of vibration on human health, vibratory roller with poor damping effect is not popular.
