Q:Where is the driving wheel of the steel roller?
Full hydraulic drive, stepless speed change, eighth generation hydraulic single drive single steel wheel roller (SSR200AC-8)
Q:Asphalt mixture pressure should give priority to the heavy duty tire roller compaction,
As for modified asphalt mixture are generally due to discontinuous gradation, rub tire roller will make the coarse aggregate surface, causing structural depth decreases, and even bleeding. So generally use vibratory roller is better.
Q:What's the difference between a three wheeled steel cylinder roller and two wheeled steel cylinder roller?
This difference. There is no need to say the difference between them. Because generally, if they are all machines that the road must be equipped with, there are two types of machinesRoad asphalt mixture shall be compacted with the following machinery:Double drum steel roller: 8t;
Q:31 How about roller?
Accessories is certainly the most matching, performance is the most fit, the price is not cheap. Substitute to a certain extent in accordance with the requirements, but do you know whether some implicit indicators can match you? Do not have the manufacturer's specialty? So there is no best product, only the most suitable for your products. According to your needs!
Q:The roller shall not turn on the rolling section, turn around, and add water to stay
So don't turn, turn around. When adding water will cause road area of water, the same will damage the situation. So it's not allowed to add water. Please feel free to take it!
Q:When the asphalt surface is rolled, why should the driving wheel of the roller be geared to the paver?
When paving asphalt surface, rollers usually use steel rollers, steel rollers are compacted without leaving traces (Che Zhe). The driving wheel of the roller is toward the paver, that is, the power wheel faces the asphalt concrete, the material is out of order and the direction is not compacted. In this way, the driving wheel can not form the wave shape because the power is insufficient, and the asphalt concrete is pushed forwards and forwards, so that the smoothness of the surface layer is more easily controlled. At present, most rollers are driven by two wheels.
Q:What's the use of this roller? What is the difference between a roller and an ordinary roller?
This is a convex block roller, is adding a layer with a convex block device mounted on the original circular surface of the base, consisting of two semicircle. This roller is mainly used for the compactness of roadbed. In general the main base material is not easy to be smooth when compacting it will be used
Q:How many tons of rollers are needed for highway engineering?
The answer. Now there are a lot of sites with more than ten tons of roller. The selection of roller tonnage shall also consider the type of pavement structure and material type. It is not necessary to use such a large amount of compaction, and the larger the tonnage, the better the compaction. If the tonnage is too large, it is possible to crush the road material and destroy the pavement structure. After all, layered compaction, tonnage is small, can reduce the thickness of the layer, or increase the number of compaction, which can meet the requirements of compaction.
Q:The front wheel diameter of the roller is 1.6m, and the width is 2m. What is the area of the roller that rotates for one week? M2
Solution: it is known that the front diameter of the roller is 1.6 meters and the width is 2 meters,The front wheel is rotated for one week, the area of the roller = the front wheel's perimeter * width=3.14 * front wheel diameter * width=3.14 * 1.6 * 2=10.048 square metersA: the front wheel is rotated for one week. The area of the roller is 10.048 square meters.
Q:Sheepsfoot road and a distinction between what work?
Sheepsfoot do stone dam project is still alive.A main work on earth, no difference, and the effect on.
