In the special chapter of the track application in the last issue.，Xiaowei took you to learn about the equipment construction of Wittgen Group. F1 The behind-the-scenes construction process of the track。This issue will bring Uyghur fans the construction process behind the track restoration.。

Smoothness is one of the important indexes in the construction control of high quality track.，If the pavement no longer meets this requirement，At this time, repair construction is required.，

The restoration of these complex tracks needs to be completed within a specific time.，So as to prepare for the new season.。For example：In the course of the game，If there is a jam on the straight at the start and end of the track，It will lead to disastrous consequences.。When braking before entering the curve，The car will start to spin out of control.，Swing from side to side！This brings a great security risk to the operator.，That is to say，The smoothness and grip of the pavement must be restored – This is the strength of the typical Wirtgen milling construction application.。

For example：In Assen, the Netherlands TT On the track，Precision milling along a straight path of start and end points 3-8 mm A tall bag，Wirtgen Milling Machine with Super Milling Rotor by Finish Milling Application，So that the track has an excellent flatness.。

In some cases，It is also necessary to adjust the slope in the designated area of the track.，This involves milling the surface layer.，It may also be necessary to mill the tack coat if necessary，The new asphalt layer was subsequently laid and compacted using a Fogler paver and a Hummer roller。

In order to improve the stability of the track，Sometimes it is even necessary to construct a new base pavement.，In this case,，Cold in-place recycling technology will be fast、Efficient construction method。Thanks to the strong construction capacity and effective and reliable construction technology of Wirtgen Group equipment，It provides professional renovation and repair solutions for many tracks around the world.。
