   The operator can flexibly select the three-gear milling rotor speed during operation.，For W 195(i) The already economical engines of large milling machines further improve fuel efficiency

In addition，The paving material that the machine needs to remove is very strong，In which that asphalt comprise a porous puddle (PMA)。When cutting these hard asphalt layer，Can produce extreme force loads.，Therefore, it is necessary to select a precisely matched round bar tool.，In order to ensure good milling performance、And that service life of the cut is long。

In this project，Nippon Road Negotiated with Wirtgen Group Sales & Services Malaysia，Decided to use Wittgen's original round bar cutter，And a hard alloy tool bit which is beneficial to cutting is adopted.。

“Years of experience tells us，The Wirtgen cold planer is extremely efficient、Versatile machine。Especially our new W 195(i) And W 205(i)，Powerful，And that mil speed is high，Excellent performance，Trusted by us。”Ir Wan Zainuddin Express。“In addition，W 195(i) Also suitable for all typical milling applications in the two-meter class，Its diesel oil consumption and cutting tool loss are low.，Higher economy can be ensured。

LEVEL PRO PLUS – Always ensure high quality milling results

In addition to the efficient and thorough removal of old pavement,，Accurate maintenance of milling depth is also an important goal in construction.。For this reason，W 195(i) And W 205(i) Intuitive as standard LEVEL PRO PLUS Leveling system——Leveling is one of the key technologies in this field.。Independently developed by Wittgen LEVEL PRO PLUS The high-tech leveling system is fully integrated into the machine control system，The current milling depth can be continuously compared to a preset target value。

Excellent completion of milling tasks

All cold milling machines involved in this milling construction are front discharge models.，Therefore, the whole milling construction process is optimized.：Unload the waiting truck without interruption，Ensure smooth milling process；And then，The milled asphalt is reused in a nearby road construction project.，Save and protect the environment，After excellent completion of all links including road surface cleaning，Ir Wan Zainuddin Praise：”Once again, the Wirtgen cold planer has proven its strength.，Reliable、Efficient，Live up to its reputation！”

   Wittgen、Fogler and Humvee's trusty machines played a decisive role in the overall runway overhaul project.

Refurbishment of asphalt pavement by Vogler wheel paver

Using the Fogler Paver Pair 4,000 m x 60 m The runway is paved.，This paving operation follows the milling task。That is to say，Need to be in the middle of the runway（Zone 1）Paving 25 cm Thick asphalt pavement，In the more distant Zone 2，The paver only needs to be refurbished 7.5 cm A thick surface layer。

Two sets were used in the construction AB 600 TV Super 1803 for Telescopic Screed-3 Wheeled paver。Because the airport construction site needs to travel a long distance.，Wheeled pavers can play an important advantage.：Relying on its own wheels for rapid transshipment，It uses 6x4 or 6x6 Drive scheme，Travel speed up to 20 km/h，The powerful hydraulic independent drive also ensures that the machine has strong traction during paving。
