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?
In this case, the local government can be reflected in the situation, and for the corresponding losses caused by residents, or compensation.
Q:Asphalt mixture pressure should give priority to the heavy duty tire roller compaction,
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:What's the inner structure of the roller?
The structural types of vibration wheel are relatively common at present. They are through shaft type (which can be divided into single shaft type, inner and outer sleeve shaft type), welded disc type plate and detachable box type (also called independent vibration chamber).
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:How many tons of rollers are needed for highway engineering?
The answer. Now there are a lot of sites with more than ten tons of roller. The selection of roller tonnage shall also consider the type of pavement structure and material type. It is not necessary to use such a large amount of compaction, and the larger the tonnage, the better the compaction. If the tonnage is too large, it is possible to crush the road material and destroy the pavement structure. After all, layered compaction, tonnage is small, can reduce the thickness of the layer, or increase the number of compaction, which can meet the requirements of compaction.
Q:What are the tonnage of the rubber tyred rollers?
The main part of the river is 26 tons, 30 tons. It's around here
Q:The front wheel diameter of the roller is 1.6m, and the width is 2m. What is the area of the roller that rotates for one week? M2
Solution: it is known that the front diameter of the roller is 1.6 meters and the width is 2 meters,The front wheel is rotated for one week, the area of the roller = the front wheel's perimeter * width=3.14 * front wheel diameter * width=3.14 * 1.6 * 2=10.048 square metersA: the front wheel is rotated for one week. The area of the roller is 10.048 square meters.
Q:What is the advantage of vibratory vibratory roller in comparison with vibratory roller?
Vibratory roller is more widely used than vibratory roller. As the bridge deck is not suitable for vibration compaction of asphalt compaction and repair, vibration and oscillation roller can be used oscillatory compaction. In this convenient Jiangsu horse roller is good, I have a JMD810H, bought 2 years, no problems, the quality is good. You can think about it if you buy it. I hope I can help you.
Q:How to prevent sticking wheel on modified asphalt pavement using rubber tyred roller?
This is a dilemmaSuggest finding a bright migrant workerThe construction of diesel spray blasting,The standard of control is "non stick"
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.
