Introduction of Double Drum Roller
The road rollers can be divided into single drum ones and double drum ones. Our company, Aido Company has these both two types for sale.The biggest difference between single drum roller and double drum droller is that it has two drums instead of tires behind. That’s a characteristic which has its strength and shortcoming at the same time. A double drum roller can flatten ground in front of and behind the roller at the same time, while the single drum one can only compact on the front at one time.
It has double drums and no tires, so it uses these two drums to walk forward. Because of this, you can’t use this kind of machine for specialized work. They just work better on relatively flat ground or ground with gradual grading. They are not that suitable for slope.

Advantages of Double Drum Roller
The most significant advantage of double drum roller is efficiency. After all when you are operating the roller, two drums will work on the same time, it’s double area when compared with single drum roller.That will certainly improve working efficiency and economize manpower.
Because of better power and efficiency, double drum roller can work greatly on asphalt.The machine can flatten ground of highway with fast speed and high accuracy.
The double drum roller can also work on areas like parking lots or new roads.Before paving, it can compact the surface. Then after the pouring phase, the single drum roller can also compact the pavement and make it even.
The double drum roller is a kind of heavy duty compaction machine, it weighs at least a ton. The power of double drum roller comes from its pair of steel drums. Because of its heavy weight and giant power, it can be driven over most of the substances.
Drum rollers are absolutely the most useful machine when you need to compact and flatten surface of construction site. When working on asphalt ground, the double drum roller is your best choice without doubt. For most other compaction job, the single drum can be a good choice too. Anyway, you should consider your working requirement and working site first. Then you can choose the most suitable kind to help your business efficiently.

Compaction Performance of Double Drum Roller
- The compaction performance is the basic function of the steel wheel roller, which reflects the final operation effect of the project, including flatness, compaction, uniformity, etc.
- Compared with other types of rollers, steel-wheel rollers are mostly used for the implementation of asphalt pavement surface lamination, and the compaction degree has very strict requirements.
- If the compaction performance of double steel roller is defective, it will affect the final construction effect. For example, in the compaction operation, the aggregate is not rolled evenly or the aggregate is broken, which will reduce the road surface roughness, affect the safety and comfort of driving in the later period. At the same time, it is easy to appear the quality diseases such as overburden, loose and pushing.
- When using double steel wheel roller to thin layer pavement or bridge deck pavement, it will produce great impact.
- The surface aggregates are damaged so as to appear crushing phenomenon, which seriously damages the aggregate gradation characteristics, especially for the special structure of the mixture, aggregate more obvious impact.
- In order to ensure the compaction effect, it is necessary to ensure that the roller has good compaction performance and operates according to professional standards.
- According to the structure characteristics of the roller, set the working parameters, including rolling temperature, running speed, layer thickness, etc., to avoid resonance and vibration problems caused by improper vibration impact interval or vibration reduction performance Settings, affecting the pavement smoothness.
Working Parameter of Double Drum Roller
In order to give full play to the function of the steel roller, the working parameters must be set in advance, including the value of working quality, vibration parameters, driving speed and so on.
1.The rolling speed of the work efficiency and compaction effect has a key impact, it should improve the work efficiency when ensures the compaction effect at the same time.
The lower rolling speed can transfer more energy to the layer material and affect the construction material structure. However, it will also result in unsustainable spreading operations and reducing the compaction quality.
While higher rolling speed can improve the work efficiency, but it is easy to appear problem of material moving, and reduce the compaction flatness;
2.Whether the setting of amplitude and frequency is reasonable determines roller compaction performance. In the face of the differences between different compacted material performance, we need to adjust the amplitude and frequency, to avoid appearing low value to affect compaction performance. Or appearing problem of wheel vibration amplitude and vibration acceleration being too high, so that compaction performance and structure of roller will be affected.
In general, the vibration frequency of double steel roller should be kept constant to reduce the change of acceleration caused by frequency change and improve the compaction quality.
