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.

Q: Cement layer construction, do not roller compaction, OK?: First, I want to tell you that if you simply pour concrete, just a vibrating bar or a flat vibrator! The roller doesn't work at all!

Q: Why use this roller when paving asphalt?: The rubber tire roller through type kneading function, all work in horizontal and vertical direction, so that the mixture particles move and rearrange and close to each other, forming a contact surface and the roller contact the most stable aggregate. On the one hand to ensure the degree of compaction, reducing the double steel wheel road damage on aggregate; on the other hand, the aggregate and roller contact surface increases, under the same compaction condition, effectively reduce the possibility of aggregate crushing, improve the usage function of pavement.

Q: What are the benefits of using it?: The compaction process has kneading effect makes the compaction layer, and does not destroy the embedded particles, uniform and compact. Good mobility, fast (up to 25 km / h), roads, airports and other projects for the compaction of the cushion.

Q: What's the difference between the German BMW roller and the German BMW? Which is better? Thank you for your advice: BMW is roller imported from the German company BMW; BMW case is the German BMW company in Shanghai China company, BMW roller assembly, in order to distinguish the two different names, the price is also different; BMW Dalian canal Yici engine, some structure also is domestic production; there are great differences between BMW and Germany the quality of! Currently the best brand roller is Sweden Dynapac produced Dynapac roller!

Q: How about a Luoyang road roller?: Recommended to buy well-known trademarks, such as mountain push, Xugong roller, quality and after-sales service better.

Q: Then the grass-roots construction to the stability layer, including two ash macadam stage, will use 21T iron three times repeatedly rolling the road. Excuse me, iron three rounds again in this process, the role and vibration roller what is the difference?: Why not use vibratory roller compacted base, mainly because the composition of the two ash macadam, two ash gravel is composed of lime, fly ash and gravel mixture, the mix and then transported to the general in the construction site. After completion of paving compaction after curing can be survived, but must adopt smooth wheel roller rolling roller, if the vibration, vibration in the process, two ash gravel will occur somewhat like segregation, segregation of concrete, gravel and lime fly ash is separated from the. Crushed between the two ash separated, leading to maintenance survived, so we cannot use vibratory roller.

Q: What's the width of the 12 ton roller?: super heavy (16 tons) pressing wheel distinction: single steel wheel and double steel wheel, three wheel, tire according to the compaction principle: vibratory and static effect of impact roller, roller, roller combination at present commonly used in Engineering: single.

Q: Why does the roller shake from the building when it's past the building?: When the rollers are on, the front wheels are vibratingRoller vibration when the work tonnage is generally around 30T, the housing has a certain impactIf you have caused some damage to your building, you can claim certain compensation

Q: What is the design principle?Experts: how to build a large machine --- roller, the internal structure of its drum (with the brief introduction of the best)? What is the design principle? What is the maximum weight of the drum at present? What kind of traction equipment do you need? Thank you very much.: The structural types of vibration wheel are relatively common at present. They are through shaft type (which can be divided into single shaft type, inner and outer sleeve shaft type), welded disc type plate and detachable box type (also called independent vibration chamber).
