Q:Why can't we use the tire roller in the modified asphalt road?
Can not generally say that modified asphalt pavement can not use tire roller. We know that SMA asphalt layer can not be used in tire roller rolling, because the SMA asphalt mixture aggregate gradation and aggregate gradation is not continuous, relatively large, and the modified asphalt content is relatively higher, when using the tyre roller, tire roller is very heavy, tire ground the pressure is large, easy to SMA asphalt layer of modified asphalt mixture from the voids in the extrusion, it is not up to the role of the SMA asphalt layer, from the analysis of this meaning is not used tire roller. For the highway, the asphalt layer has three layers, in order to save money, in the surface layer is used instead of the base asphalt, modified asphalt, and this phenomenon is not that modified asphalt pavement can not use tire roller, on the contrary, the asphalt pavement is matched with the need of tyre roller to achieve good compaction effect, including modified asphalt. The asphalt is hot, the tire will bond in asphalt, a tire pressure will mark is not scientific, if afraid of this and that, without the use of tyre roller, for the asphalt pavement, is to pick a watermelon seed lost performance for the asphalt pavement compaction effect, not only is the most terrible.
Q:How to choose a second-hand roller?
Roller is an indispensable road equipment in modern road construction. It is widely used in filling and compacting operations of large scale projects such as highways, railways, airports, runways, dams and stadiums. Compared with the new machine of second-hand roller with good price, steel in the world will give you a brief introduction about, how to buy second-hand roller.First, the use of time is a key factor in determining the price of used rollersTreatment of rollers and other construction machinery, although our country does not have the same as the mandatory scrapping of the car, according to the annual use of 2000 hours to calculate, roller service life is generally 10 years. Due to the new roller, the normal use of the case, five years without heavy repair, the machine during this period generally has a good cost performance. The price of used rollers is usually depreciated by 20% in the first year, and then decreased by 5% each year to calculate the basic price. First year depreciation 20%, second year depreciation 15%, third year depreciation 10%, fourth year depreciation 5%. Fifth years after the machine parts, with normal wear and aging, plus some unpredictable factors, the probability is greatly increased when the need to overhaul the roller prices in general, because of the individual machine product phase is different, there are great differences. After 10 years, the roller, with the impact of technology and other factors, the price is generally maintained at 20% below the price of new machines.
Q:When using 20T heavy vibratory roller, what is the backfill thickness per layer?
2, subgrade backfill using heavy roller, in order to ensure backfill quality. The construction of subgrade soil subgrade must be layered backfilling, each layer backfilling thickness is less than 30cm, roller with 18-20T times the number of not less than four times, with cutting ring check its density to meet the design requirements must be.3, after the roadbed forming, should be central line, elevation, vertical and horizontal gradient test, qualified immediately after maintenance, after the expiration of the maintenance report submitted to the quality inspection department for acceptance testing.
Q:In the process of asphalt pavement construction, can the wheel roller use diesel oil to clean the surface of the wheel?
Can use the tyre roller, the use of diesel surface cleaning using steel roller, use plain water cooling and cleaning the surface, 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.The road roller belongs to equipment in construction machinery category, widely used in Embankment Compaction of highway, railway, airport runway, dam, stadium and other large projects, can crush sand, semi viscous soil, the stability of subgrade soil and asphalt concrete pavement.
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:Building construction, taking vibratory compactor as an example, illustrates the method of compaction Matters to be attended to?
Compaction method has three principles: (1) first light and heavy: (2) first slow, then fast; (3) first low and high;It should be noted that: (1) the time of compaction, soil base must be appropriate water content, asphalt mixture temperature appropriate.(2) the role of the regulator - first slow and stable, is to maintain the new layer without deformation:(3) crown holding by low in high RCC will guarantee;(4) asphalt mixture rolling - watering appropriate, non stick office building, but quickly cool down
Q:What is a roller?
The road belongs to the road equipment in construction machinery category, widely used in Embankment Compaction of highway, railway, airport runway, dam, stadium and other large projects, can crush sand, semi viscous soil, the stability of subgrade soil and asphalt concrete road surface
Q:How do I charge the roller electromechanical bottle?
The engine comes with a little accelerator, and the generator will recharge itself
Q:31 How about roller?
In fact, each enterprise has its product positioning, the use of the object has its choice models considering how to choose from that the highest cost-effective products, eyes of the beholder.
Q:Why is it forbidden to apply diesel to the roller? In the process of roller compaction, to prevent the wheel sticking of asphalt mixture,
Diesel oil is very corrosive to asphalt, and it must have potential quality problems, but it is not too bigIf you are in the construction process, supervision, the owner does not allow you to use diesel oil, you can buy cottonseed oil to fight, the price is cheaper than diesel, and the effect is much better than diesel, asphalt is also no damage
