October twenty seventh in the morning，From Pingyu to Zhengyang Yuecheng Section of Daguang Expressway（Short name“Pingzheng Expressway”）Centralized maintenance project construction site，The reporter saw such a scene.：Heating machine、Scarifier、Heating machine、Remixer、Paver、Thirteen large-scale maintenance equipment, such as road rollers, are arranged in a string on the construction pavement.，Like a group of slowly moving train，This group“Maintenance special train”Everywhere you go，“Eat”Into the old road，“Puke”A new way out，The old road takes on a new look in an instant。

This group“Maintenance special train”Occupying only one carriageway，With the unit slowly moving forward.，New road surfaces are constantly being created，Simultaneous restoration of signs and markings，The maintained carriageway is passable.。That is to say“Maintenance special train”Rake the old pavement heat loose，And then adde a proper amount of regenerant、Asphalt and fresh asphalt mixture，After mixing、Spreading、Compaction technology package，A brand-new road appeared in front of people in less than an hour.，It makes people call it magic.，Such maintenance pavement“Magic skill”It is called hot in-place recycling technology.。

For Henan Pingzheng Expressway Development Co., Ltd.，For the first time, the hot recycling technology of in-situ mixing is an iterative upgrade of the traditional maintenance technology.。In recent years，With the new technology of highway maintenance、New materials、New equipment、Continuous popularization and application of new technologies，Three-year Action to Promote Highway Maintenance and Management in Henan Province Encourages All Highway Operating Units in the Province to Make Bold Attempts“Four new technologies”Application，The recovery rate of old pavement materials reaches 100 percent%、The revolving interest rate is 95.%The above objectives。In order to fully implement the key tasks of Henan Provincial Department of Transportation，Combined with the actual situation of the road section and technical feasibility analysis，Henan Pingzheng Expressway Development Co., Ltd.“Dare to be the first”The boldness of，Construction process of on-site remixing and hot recycling technology，Creatively solve the problem of traffic interference caused by traditional maintenance technology、The construction efficiency is low、High cost、A big problem of environmental pollution。

Wu Qiang, general manager of Henan Pingzheng Expressway Development Co., Ltd., told reporters.，This is the first time to adopt the hot recycling technology of in-situ re-mixing in Pingzheng Expressway, which is a bold attempt to the four new technologies.。Reuse of waste materials is the key to the technology of hot in-place recycling，Asphalt regeneration，100% of the material can be realized%Recycle on the spot，And has low cost、And that construction efficiency is high、Advantages of low carbon and environmental protection，To alleviate the contradiction between highway traffic and maintenance construction、Greatly reduce the comprehensive cost of highway pavement maintenance、Promote new process and new technology、It is of great significance to develop green transportation.，It really realizes cost reduction and efficiency increase.、Green and environmental protection。

It is reported that，The total length of the maintenance project of Pingzheng Expressway in 2023, which was constructed by Zhoukou Longxing Highway Engineering Co., Ltd., is 28 kilometers of single lane.，It covers an area of 110,000 square meters。Implementation of the new technology，It is estimated that at least 15 percent%Above cost control，The original construction period of 30 days can be controlled to complete the maintenance task within 15 days.。
