FAQ
- 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.
- How much for an hour, how much money a day, oil?
- Your question is incomplete. If it is a vibratory roller, it can be divided into double wheel and single steel wheel. Single steel wheels are used in earthworks and crushed stone subgrade. Double steel wheels are used on asphalt.
- in order to increase the pavement permeability, the total mass of not less than 25 tons.
- As for modified asphalt mixture are generally due to discontinuous gradation, rub tire roller will make the coarse aggregate surface, causing structural depth decreases, and even bleeding. So generally use vibratory roller is better.
- The asphalt pavement here is divided into three layers, the two layer with rubber tire roller for rolling, the surface layer is needed for the rubber roller, wherein the two layer is below AC, the top layer is SMA series.
- The asphalt aggregate ratio and slag amount is more than 6% SMA can not use leather wheel, this is the result of the test section, the rub mastic floating that the depth of the surface structure reduces in this case leather wheel, skid resistance is reduced, skin wheel function is rubbing that is dense, so more suitable for dense graded mixture.
- The difference between tracked roller and wheel roller
- Heavy duty rollers include horizontal vibratory rollers, which have their own weight plus vibration force to make the road more solid and flat, suitable for large road laying.
- What are the tonnage of the rubber tyred rollers?
- 1. rubber tyred roller has 16 tons, 20 tons, 26 tons, 25 tons, 26 tons, 30 tons and so on.2. tyre roller is a kind of machine which is used for compacting the road by a plurality of pneumatic tyres. The roller of tyre roller adopts pneumatic tyres, usually 3~5 front wheels and 4~6 rear wheels. If the change of inflation pressure can change the ground pressure, the range of pressure regulation is 0.11 ~ 1.05 mpa. The tire roller adopts hydraulic, hydraulic or mechanical transmission system, single shaft or full axle drive, wide base tire, articulated frame structure, three point support. Compaction process has the role of rubbing, so that the compaction layer particles are not damaged and embedded, homogeneous and dense. Good maneuverability, fast speed (up to 25 km / h).
- Why is the roller driving force facing the paver when the asphalt is laid and rolled?
- The exact requirements should be paved and rolled according to the direction of the road.
- May I ask who knows the vibration Shantui 22 tons roller much money, thank you
- Are you going to buy it?! If you want to buy I can help you ask, my home is in Jining City, my friend in mountain plant, and can be a lot of money.
