I need a roller, but the search found different working principles of rollers
The biggest difference is that the hydrostatic roller is used to press asphalt, that is, the road surface, the road will be used laterVibratory roller is used to press the earth, the road is full of its life, the first few layers of the foundation will be used before the static roller
The hydrostatic roller is obsolete and is a roller compactor that is compacted by its own weight.Vibratory rollerBy using the centrifugal force principle of vibration, the compaction strength is increased.purpose1 road, the road wheel compaction2 compaction when asphalt is laidPS: some vibratory rollers have the function of switching between vibration and static pressure
Hydrostatic roller is the most common is 3 steel wheels, produced by walking the compaction effect, vibration in rolling oil single steel wheel and double steel wheel, can static pressure, but also can make the steel wheel vibration, there are two stalls, high vibration and low vibration, high Zhenneng reached more than double the compaction effect now, hydrostatic roller are eliminated for many years.
