Q:Why should we use the rubber tyred roller in the construction of the asphalt pavement?

Initial pressure is generally used by steel wheel rollers, but there will be a phenomenon of passing, that is, the front of the roller mixture is subjected to lateral movement of pressure, and may cause cracks after compaction. Also useful for the initial pressure of the rubber wheel, but because the initial temperature is higher, the mixture easily adhere to the tire, and the traces are not easy to remove, so there is a lot of opportunities for the rubber wheel to re pressure.I think there are two main advantages of rubber wheels:1., rubber wheel compaction is a kind of kneading type compaction, compaction effect is good, and can remove the steel wheel compaction generated small cracks;2., the rubber wheel compaction will make the mixture of asphalt, mineral powder, fine aggregate and other forms of adhesive floating, so that the upper surface more closely, waterproof better.The disadvantage or non applicability of a rubber tyred roller:

Q:What about Luo Jian Road Roller?

In the domestic goods are on the level, the brand is very old, the higher price, the price cheaper than Xugong, Xiagong, quality than Ketai, through good.

Q:Excuse me, is there a 80 ton heavy duty roller?

No, at least the domestic roller is not so high, the general vibroll maximum is 28 tons, even if the tyre roller is only 30 tons, but the vibroll can rely on the vibration compaction effect is much higher than its own weight, you can refer to 28 tons of vibration of Liugong roller

Q:XCMG alarm lamp for vibratory roller

As the global economy is still in a slow recovery period, coupled with China's Roller Road enterprises export major market recovery is weak, in 2013, the road roller exports situation has improved, but the growth rate is weak. In 2013, the roller main production enterprises exported 3395 rollers, an increase of 1.8%. More than 200 enterprises export roller this year, Xugong, Xiagong, Liugong, Luoyang Road, Liuzhou, mountain and other 6 enterprises. This one, because of the influence of brand and overseas channels, up to 752 units of export Xugong roller, total sales of 18.5%; export 693 units Xiagong roller, has accounted for 42.6% of total sales; Liugong exports 556 units accounted for 39.85%.

Q:The width of the road is four meters. The roller runs for half an hour. It can press a large area of road

Solution: it is known that a roller runs 25 meters per minute and the width of the roller is =4 meters,Get the roller area per minute of the roller= running length per minute * width of road=25 * 4=100 square metersAnd roller drive for half an hour, half an hour =30 minutes,Roller must be driven for half an hour= pressing area per minute * road time=100 * 30=3000 square metersAnswer: roller run for half an hour, can press 3000 square meters of road.

Q:Xugong has 22 tons of rollers weighing several tons

22 tons is the nominal weight of the factory, the actual weight is about 21.5 tons. Generally speaking, the weight of more than 21 tons, even 22 tons.

Q:Why do different types of roller are used for road laying, initial pressure and final pressure?

The rolling shall be carried out along the centerline of the road. The rolling speed is uniform, the wheel track overlap width, the two wheel roller is 30CM, and the three wheel roller is half of the rear wheel width.Baidu Library in the road construction program and roller construction technology and other related articles, suggest to take time to see.

Q:In the process of asphalt pavement construction, can the wheel roller use diesel oil to clean the surface of the wheel?

Generally, the use of steel roller, use plain water cooling and surface cleaning, the use of rubber tire roller, the use of diesel oil, it is only in the beginning or sticking wheel rolling, rolling wheel, after a while, the surface temperature, there is no need for.In the rolling, mainly by spraying some solvents make the wheels not sticky asphalt mixture, like diesel, oil film of asphalt mixture is damaged, and the cost is high, the construction unit and the use of rapeseed oil, water washing powder, the specification also mentioned some. In general construction, more diesel and water ratio of 1:1 solution is used.

Q:I recently wanted to buy a 20 ton roller, but I don't know which one is better Now know, a long work, ha, Liugong, but they say roller their good, here also please comment

XCMG is good, but the price is too expensive, not worth the roller than buy the mountain! Cost-effective, good service!

Q:The working principle of roller

The working principle of the roller is as follows:1 、 roller is a method of using mechanical weight and vibration to repeatedly load the compacted material to overcome the cohesion and internal friction between the materials.2, to exclude its internal gas and water, forcing the particles between the displacement, wedge close each other, increase the density, so that it reaches a certain degree of compaction and integrity of the operating machinery.
