September 19-22nd，With intelligence、Safe、The Wittgen China Technology Festival with the theme of sustainable development opened in Langfang, Hebei Province。Industry elites gather here.，Star products compete for debut，Guests and customers present were enthusiastic.。

Enter the third day of the activity，The popularity remains unchanged.，The scene was crowded with people.，New products、New technology continues to ignite the scene atmosphere。

Fogler 3D Digital Control Paving Technology、Electric Hummer Small Roller Without Diesel Fuel、A series of new technologies, such as Wittgen high-performance pavement recycling technology to achieve green maintenance, as well as a full range of new models of the fourth country, attracted the attention of the audience.。

At the same time，A scene about《High Performance Pavement Regeneration Technology Based on Synchronous Paving》Expert lectures are in progress.，Next, let Xiaowei take you into the scene.，Let's learn about this technology.！

With the rapid development of highway transportation in China,，Country、The provincial trunk highway network has been gradually formed.，The proportion of new highways is decreasing year by year.，Alteration、The proportion of overhaul projects has been expanding.。If the pavement reconstruction continues to adopt the traditional way,，It not only increases the asphalt and gravel needed to rebuild the road surface.，Destroy the surrounding environment，But also can easily cause environmental pollution.。

Transportation industry is one of the main forces of carbon emissions.，The challenges are enormous，Therefore, the cold in-place recycling technology of foamed asphalt based on synchronous paving has a very broad development prospect.。

Wirtgen is the leader and innovator of cold recycling technology.，Through the cold recycling machine W 380 CR Milling can be completed、Spray、Mixing、Receive the material、Transportation and other functions，One fleet can complete cold recycling maintenance of one road，It not only simplifies the equipment configuration、Increase the continuity of construction process，Effectively improve construction quality、Shorten the construction period、Save resources。

This construction process is very flexible and efficient.，The application scenario is wide，It has been successfully applied in many provinces in China.，The total application area exceeds 10 million square meters.。（Click on the picture to view some application cases）

With W 380 CR As the core, the foam asphalt cold in-place recycling unit works together.，Cement spreader in front、Water tanker、Binder tank truck for assistance，Followed by Fogler paver、Hummer roller for paving and compaction，The damaged pavement will be regenerated at one time。Through the comparison of the medium and long term performance of the regenerated road section，The advantages of the new technology are very significant.，The technical specialist also gave a detailed explanation.：

Energy saving effect：The unit energy consumption of foamed asphalt cold in-place recycling mixture is only 29% of that of hot asphalt concrete.5%，The unit energy consumption of cement cold in-place recycling mixture is only 76% of that of traditional cement stabilized macadam.7%，The energy-saving effect is very remarkable.；

Social benefit：Utilize 100%Old pavement material，A large amount of engineer investment can be saved.，Protect resources and save costs；Leave out that excavation of the old pavement structure layer、Clear、Transportation and other processes，Shorten the construction period，Thereby reducing traffic disruption times。

In the live demonstration session，The guests and customers present showed great interest in the new technology.，It can be seen through the scene. W 380 CR The process of regenerating the fleet in a coordinated way，It can intuitively feel the cold regeneration process in place.。Through the explanation of the on-site lecturer，The characteristics of this process can be clearly understood.，The reason why there are so many economic and environmental benefits.。

In the course of construction，W 380 CR The advantages are obvious，Seamless regeneration of one lane at a time，Extremely efficient construction，But also can remarkably eliminate that inhomogeneity of the original pavement material.，And the composition of the recycled mixture is accurately controlled according to the preset mixing ratio.，Greatly improve the quality and service life of recycled pavement。The technology is in rapid construction.、Improving pavement structure performance and saving energy consumption、It has great advantages in reducing carbon emissions.。

Find out through live technical lectures and demonstrations，Wirtgen cold in-place recycling technology can achieve high efficiency of highway maintenance、Intelligent and low-carbon，Adapt to the new requirements of road maintenance technology and equipment，At the same time, it will also provide new technical solutions for the high-quality development of highway infrastructure under the background of double carbon.。
