Q:What is the difference between 18t roller and vibratory roller? What's their respective function?
Your problem is not comprehensive. If it is a vibratory roller, it will be divided into double and single steel wheels. Single steel wheels are used in earthwork and Macadam foundations. Double steel wheels are used on asphalt
Q:Shaanxi impact roller manufacturers which scale is relatively large?
To improve the entire strength and uniformity of subgrade treatment; impact rolling loess foundation or soft foundation collapsibility before filling, to meet the requirements of bearing capacity and stability of foundation; old road, gravel road, cement concrete pavement and the use of impact compaction technology renovation, can speed up the progress of construction, to project quality request and so on. At present, in addition to very few provinces, municipalities and autonomous regions, most of them have been widely used.
Q:Does the vibratory roller affect your health?
They are all shock proof. When you open, watch for the noise
Q:How many tons are there in the maximum roller?
At present, some provinces in China have been forced to use more than 25t heavy-duty tire rollers in the bidding of expressways, which should be paid special attention to when purchasing.The roller main technical parameters including work quality, vibration force, vibration frequency, amplitude, climbing ability, diesel engine model and power, roller quality equivalent work normally with the exciting force is greater, the vibration frequency and amplitude range is more series, climbing ability is stronger, the power of diesel engine the bigger is better, but it is important to note that with a smaller turning radius as well, so you can bring more convenience for construction in the process of storage and transportation, steering.
Q:Who has a roller for me?
I know there is a road roller in Meishan, and he knows quite a lot of people who do road rollers, loaders and excavators. I used several rollers there, and now I have one on the construction site. The colour is good, and the labor is good.

There are many styles and many models, so the prices are different. Usually within 3w. 1W above!

If the roller wheel width is 2m, the pressure is the pressure every time he 2m width, and when the left pressure 2m pressure, pressure right now, but the roller can not allow left traces of transfer line toward it has pressed to pressure, but to shift to the left 0.1 to 0.2m pressure, and this is the two time they offset the pressure of overlap width. Do you understand that?
Q:Why should not be modified asphalt mixture roller compaction, and dense asphalt mixture should be used tire roller compound pressure?
For dense bituminous mixture aggregate due to small and continuous gradation, the tyre roller has the rubbing function makes the compaction layer of particles without destroying and interlocked, uniform and compact.
