- Q: Is the roller on the road?
- 4, if the roller running normally, and through the municipal engineering administrative department approval, because the transition needs no violation driving. It is only after the accident scene has been identified that the conclusion can be reached.
- Q: In the practical process, which one is the most practical? May I ask who can help me explain?
- the airport runway and the F1 track level is not the same, the higher the level, the higher requirements on and micro the overall structure of the pavement radian, the rubber wheel can be very good to meet these requirements, of course, only in the high requirements of the road we can see this kind of roller, usually in the side is not 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: How does the municipal asphalt pavement budget do not have a wheeled roller?
- Municipal asphalt pavement construction quota, already contains a roller and paving machine cost, you can audit and said, don't fixed costs, change according to the market price of Jixietaiban, and don't forget the large machinery import charges.
- Q: What is the concept of the static line pressure of roller?
- I can give you a method for calculating the line pressure: the line pressure = the weight of the steel wheel, W (kg) divided by the width of the steel wheel, L (CM)What is line pressure?. This is where the pressure is concentrated in the narrow part of the contact surface. In fact, the state of the line.
- 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: How about mountain road roller
- Shantui roller is really rubbish, the cab and people can not do, no vibration teeth are too sharp, dry, claw out, customer service is extremely garbage, I really regret to buy a mountain,
- Q: 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.
- Q: When the new high-speed road roller is used to press the road surface, it will cause cracks in the surrounding houses. What are the criteria for compensation? How many meters away from the subgrade is the range of compensation?
- The general compensation is calculated according to the area of the residents.
- Q: I have never touched, very strange, roller okay? By the way, under the drive must pay attention to, to the older generation back to 150Friends to learn to drive roller, I have never touched, very strange, roller okay? By the way, we must pay attention to the following road roller
- Do you want to open what is the single roller, Ganglun repair pavement or asphalt pavement temperature, double rigid gear
