8ton Double Drum Vibratory Road Roller

Q: How does the roller run in a straight line?: The roller presses 1/3 of the wheel as required. You can make a mark on the front cross bar and then follow the mark! Thanks for taking it. If I don't make it clear, leave a message

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: The front wheel of a road roller is known to be cylindrical, with a width of 2.5 meters and a diameter of 1.2 meters. The front wheel rotates 8 minutes per minute. The 1. roller takes 20 minutes from one end of the road to the other. How many meters is the length of the road?. 2. what is the area of the road roller from one end to the other end of the road?. Process and description: 1, turn 8 laps per minute, 20 minutes, a total of =20*8=160 circles;2, because the diameter is 1.2 meters, so a turn is equal to the front wheel perimeter =3.14*1.2=3.768 (meters);

Q: I would like to ask, 18T roller layered centimeters, compaction is the most appropriate?: Xugong's name is 18J, right. The basic stone can be compacted at 25-30 centimeters, and the lime soil can be compacted by 40 centimeters, but..! Density and tonnage are related, the pressure of the same depth, the difference is the density of it, perhaps we are colleagues, do not know if I can help you, the management here is not a thing, I am not allowed to review

Q: The dangers of young people turning on rollers: Negatively speaking, lack of social experience is actually eat less, so you eat more slowly understand why the boss says that they make pressure on how how pressure, not with his nonsense, you say to him, he more angry, more than 10 hours a day and the boss asked people, a person carry not to live! I also drive the road ~ in the construction site must listen to.

Q: Roller brake lock why: 3, wear plate return tension spring failure;4, the brake master cylinder push rod to adjust properly, there is no freedom of travel (four wheel lock);

Q: Difference between single steel wheel roller and double steel roller: Rubber roller and double steel roller is generally in asphalt concrete pavement use; rubber tire roller plays a role, enhance the degree of fit between aggregate and asphalt concrete, reinforced compactness; double steel roller has the effect of asphalt concrete.

Q: There are several types of impact rollers: Single steel wheel vibratory roller (mechanical drive or full hydraulic drive): 12T/14T/16T/18T/20T/22T/26TDouble steel vibratory roller: 12T/13T/14TThree wheel static roller: 1518 / 1821 / 2124 (or 2125)Tire roller: 16T/20T/26T/30T

Q: When using 20T heavy vibratory roller, what is the backfill thickness per layer?: The measurement of unbalance can be carried out online or offline. Due to the unique frequency meter technique of the East, the measured unbalance amplitude and phase have high precision. Theoretically, the amplitude accuracy can reach 0.1%, and the phase accuracy is less than 1 degrees. Vectors can be synthesized and decomposed.

Q: What is the cause of soil cracking when subgrade is pressed by subgrade?: When the moisture content of backfill material is too large, cracking occurs in the course of pressing, and it will become loess when it is serious. The optimum moisture content of backfill is between 9% and 11%.
