It is the king's way to know the technology of milling and planing

As the branch of milling and planing, the technology of milling and planing is more and more applied to the pavement maintenance in China. So what do you know about this milling technology? The following small editor from what is the fine milling planer, the use of fine milling planer and the advantages of fine milling three aspects to give you a brief introduction.

What is a fine milling planer

Fine milling is a variety of standard milling technology, the difference is that the spacing of the cutter is smaller than that of the standard milling. The cutter spacing of the milling planer is generally less than or equal to 8mm, so the cutter on the rotor is much more than the standard rotor tool.

Equipped with a milling machine milling planing rotor, pavement texture interval milled in 3mm to 8mm, the maximum milling depth of 50mm.

Use of fine milling and planing

Milling planer with fine milling and planing texture is fine, with different tool spacing and milling speed, milling planer has a wide range of applications. It mainly includes the following four uses:

1. improve the friction coefficient of pavement

With the increase of the service life of the road, the surface wear of the road will cause the pavement to lose its anti skid performance.

Milling and planing can cut the aggregate on the top of the wear layer of the pavement, enhance the friction coefficient of the pavement, and improve the safety of driving.

2. improve the lateral and longitudinal smoothness of the pavement

In many cases, disease exists only on the surface of the road, and the resurfacing of milling and planing appears very uneconomical. According to the condition of the road, you can consider using precision milling method of rutting and Yong package milling, followed by a cleaning machine.

After the milling and planing, the traffic can be opened immediately, so as to improve the comfort and safety of the driving economy.

3. preparation for Thin Layer Paving

If the rutting is deeper and the deformation of the pavement is relatively large, the thin surface can be removed by the fine milling and planing, and then the thin layer paving method can be used to repair it.

This overlay to no less than the traditional milling materials. And because of the finish milling and planing in Gaoping, the smoothness of the thin layer paving is also higher.

Install the appropriate width of milling drum in small milling machine, in the road reconstruction project in milling removal marking. In addition, the polygon wheel can be used to carry on the milling planer with the sound warning belt.

Advantages of fine milling and planing

Although the fine milling technology can not eliminate the deep damage of the pavement structure, it can produce a smooth surface with ideal anti sliding capability. In particular, there are several advantages:

1. applications are widely used

Milling and planing can be widely used in rutting milling, pavement roughness recovery, road friction coefficient improvement, marking line removal and other pavement repair projects.

The width of the milling drum is from 15 cm to 3.8 m, which meets the application of various working conditions.

Milling and planing can be used not only in asphalt concrete pavement, but also in cement concrete pavement.

2. economic and efficient

The traditional milling and planing and paving need to milling a large amount of material and transportation. The thickness of the paving is large, and a large amount of new mixture is needed.

In contrast, the milling and planing material of fine milling is less, and the cost of material transportation is saved. And the construction speed is fast, and usually the traffic can be opened immediately after the milling.

If Wittgen's milling and drums fast changing system (FCS system) is used, it will be very simple to replace the fine milling drum and the standard milling drum.

3. environment friendly

Because of the high efficiency of milling and planing, the milling and planing is less, and the use of transportation vehicles is reduced. At the same time, the use of overlay materials is reduced, and valuable resources are saved. So the fine milling is an environmentally friendly process.

4. high quality of milling and planing

By fine milling, milling and planing can reach a high degree of integration. The high quality of the pavement can be obtained whether it is directly open to traffic or by thin layer.

At the same time, the texture of the pavement after milling and planing can also effectively reduce the noise level.

Nowadays, with the rapid development of China's economy, the demand for highway is becoming more and more high. The technology of fine milling and planing plays an important role in the repair of pavement diseases. It is believed that along with the wide application of this technology, the road construction in our country will be better and better.
