25 30 Used Dynapac CA25D / CA251/CA30D Road Roller HAMM Road Roller Single Drum Hydraulic System
Compared with Bai, Du vibratory roller has the following advantages:
1) The results show that the same quality vibratory roller has better compaction effect than static roller; the compaction degree of compacted foundation is higher and the stability is better.
2) The production efficiency of vibratory roller is high. When the required compactness is the same, the compaction times are less.
3) Due to the application of airborne compactness meter in vibratory roller, the driver can find the weak points in the construction road in time and take remedial measures at any time, so as to greatly reduce the potential quality hazards.
4) When the asphalt concrete surface is compacted, due to the vibration, the asphalt material of the surface layer can fully penetrate and blend with other aggregates. Therefore, the pavement has good wear resistance and low repair rate.
5) When compacting asphalt concrete, the temperature of asphalt concrete is allowed to be lower.
6) It can be used to compact the materials which are difficult to be compacted by static roller, such as backfill stone with large particle size.
7) Because of its vibration action, it can compact the dry and hard cement concrete.
8) When the compaction effect is the same, the structure weight of the vibratory roller is twice as light as that of the static roller, and the engine power can be reduced by about 30%.
