Q: Why do different types of roller are used for road laying, initial pressure and final pressure?: Technical specifications for construction of highway asphalt pavement (JTG40-2004) provides that: "the construction of asphalt pavement should be equipped with a sufficient number of roller, roller selection of reasonable combination and the initial pressure complex pressure final pressure (including molding) the rolling steps, in order to achieve the best compaction effect. No less than 5 rollers should be installed in the double lane asphalt pavement of the expressway. When the construction temperature is low, the wind is large and the rolling layer is thin, the number of rollers should be increased appropriately."Initial pressure is to stabilize the pressure, and in order to reduce the passage, it is necessary to use a small tonnage model, which should be adopted static pressure;In order to achieve the required degree of compaction, vibration compaction must be used, and large tonnage heavy compaction machines must be used;In order to eliminate the wheel trace and satisfy the requirement of the whole Gaoping, the steel wheel hydrostatic pressure should be adopted.

Q: What kind of vibratory roller is used in roller compacted concrete construction?: Specific should look at the scale of your project to choose, not a single model of the roller will be able to solve.Hope to be of help to you.

Q: The roller shall not turn on the rolling section, turn around, and add water to stay: Because of the internal and rear wheel deceleration of the turn, the acceleration of the outer rear wheel or the front wheel twist, it will roll into a dent on the inner ground and destroy the already formed road surface.

Q: How many tons are there in the maximum roller?: Static roller selection should also consider the large tonnage products, especially for the construction of the user only static roller, in order to improve the construction efficiency and compaction quality, the tonnage is best not less than 15t, after adding sand weight after weight should be more than 18t.Because of the existence of elastic deformation during the rolling process, the tire roller can play a role in kneading the compacted material, and can make the asphalt and other paving materials sealed and reduce the leakage of the pavement under the rain. According to the requirements of the new national standard "construction and acceptance of asphalt pavement" in our country, it is necessary to popularize and apply the large tonnage tire roller to re load asphalt composite paving.

Q: Roller roller steel what material? Thickness 10mm or so, which expert pointing Q235, OK?: when the old hardening layer wear off, new hardening layer formed again.A3 steel as an ordinary component, not force, but force components, but not, strength, toughness, hardness is not good.

Q: What's in the roller in front of the roller?: Inside is a set of eccentric mechanisms that vibrate by eccentric rotation with frequencies between 25-50HZ.

Q: Roller models: According to the operating weight, it can be divided into micro (1 tons less), small (1-6 tons), medium (6-10 tons), heavy (10-14 tons) and super heavy (16 tons or more)Press the wheel to distinguish: single steel wheel and double steel wheel, three wheel, tire

Q: What is the influence distance of the road roller on the building?: This generally does not affect the house, and if so, leave proof

Q: How long does it take to go to the No. 121 bus from Changshu south station to the roller road?: Bus route: Changshu 121 Road, about 22.8 kilometers1. From the Changshu coach station, about 50 meters walk to the China Men's Center (long-distance station) station2, take Changshu 121 Road, after 41 stops, to the golden home Lane station3, walk about 870 meters, to reach the roller VillageAbout 2.5 hours or so

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.
