Cities as agglomerated population、Resources、The main carrier of industry，Then the construction of transportation facilities can be said to be the pioneer of high-quality development.。The explosion of Harbin is inseparable from its developed transportation network.，Based on the new development stage，Promoting the quality and speed of urban construction and development，Only in this way can the city be more dynamic and charming.，At the same time，Always think ahead、Develop vision and plan transportation project construction，Further draw a rough and dense road network of the whole city，Tamping the city、Traffic double support。

In this interview, Xiaowei has the honor to invite the ownership enterprise of Heilongjiang Trading Engineering Construction Co., Ltd.，Heilongjiang Expressway Development and Construction Co., Ltd.（Hereinafter referred to as the Provincial High-speed Development and Construction Company）Party branch secretary、Mr. Qu Bin, Executive Director。As a practice of green construction concept、Enterprise leaders who attach importance to low-carbon environmental protection，Let's listen to Qu Zong's experience and views in the field of road construction and maintenance.！It should be noted that，This interview is conducted when General Manager Qu is not feeling well.，Still insist on completing the recording and acquisition with illness。Here, Xiaowei would like to praise General Manager Qu's professionalism.，Thank you very much for General Manager Qu's support.！

Prior to others，Must be the front

The provincial high-speed development and construction company is affiliated to Heilongjiang Transportation Investment Group Co., Ltd.，Since its inception, the concept of green and low-carbon has run through the planning of transportation infrastructure construction.。At present, the company has the first-class qualification for professional contracting of highway subgrade engineering.，Grade II qualification for general contracting of municipal public works construction，It is also the leading enterprise of asphalt pavement construction in Heilongjiang Province.。General Manager Qu said：“

Implement green construction，Practice the application of four new technologies，This is one of the highlights of our company.。By the end of 2023，The total mileage of expressways in Heilongjiang Province has exceeded 5000 kilometers.，After many years of use, the expressway has entered a maintenance period.，The future maintenance project has a lot of room for development.。

This is a key breakthrough direction for us in the future.，The future trend of maintenance must be low-carbon environmental protection.，Economical and fast process，This is in line with our company's construction philosophy.。”

As a senior person with many years of practical experience in the field of road construction and maintenance,，General Manager Qu's judgment on the development trend of road maintenance is far-sighted.。Back in 2010，General Manager Qu came into contact with Vogler Super 2100.-2 Paver，At that time, Qu Zong took an early look at the advanced construction technology and reliable and durable equipment advantages of Wittgen Group.。

“Starting with the purchase of the first Vogler Super 2100-Up to now，Our company has successively purchased the Wittgen milling machine under the Wittgen Group.、Fogler paver、There are more than 20 sets of equipment such as Hummer rollers.，My assessment is that：Advanced and practical technology、Reliable、Durable！”

In more than ten years of dealing with Wirtgen Group equipment，General Manager Qu believes that the most commendable thing is Wittgen Group's exploration of green road construction technology.，“The cost is reduced、The efficiency is improved、Scrap is reduced、Low carbon and environmental protection，The shortboard problems existing in the traditional technology have also been solved by the new technology.”，Mention the application in recent years“Four new”The sweet taste of technology，General Manager Qu is like a family treasure。“

Harbin Ring Expressway Maintenance Project、Pavement Quality Improvement Project of Ha-Tong Expressway、Road Quality Improvement Project of Toll Road in 2023 Owned by Trading & Investment GroupABid 1 Qiqihaer-Tailai Section Project, etc.，In these projects, the new technology of green low-carbon maintenance has been applied.，Including ultra-thin wearing course paving and cold in-place recycling。It can be said that in the whole Heilongjiang.，We're here‘Four new technologies’It is also in the forefront of the application.。”

In the maintenance project of Harbin Ring Expressway，The provincial high-speed development and construction company selected the complete set of pavement equipment of Wittgen Group to pave the ultra-thin wearing course.，Traffic is opened immediately after the roller rolls for 30 minutes.，The purpose of rapid maintenance is achieved.。“

This process not only saves costs by reducing material consumption，It is also helpful to improve the quality of the road surface.。

For example，Preventive maintenance or emergency maintenance of high-grade asphalt pavement or cement pavement，The 2 cm asphalt overlay is completed by fine milling and ultra-thin wearing course paving technology based on synchronous spraying.，The construction efficiency has been significantly improved.，30 days after completion of rolling Minutes to open for traffic。So that that construction can be carry out on the same day，Traffic is open on the day，Low carbon and environmental protection，Its application prospect is very broad.。”

2021，The quality improvement project of Hatong Expressway adopts the foam asphalt cold recycling technology based on synchronous paving of Wittgen Group.，It is also the first application of this technology in Heilongjiang Province.。“

Compared with the traditional maintenance scheme,，Cold in-place regeneration has better economic and social benefits.，The construction period can be saved by about half。With the gradual application of this technology throughout the country,，The future development space of cold in-place recycling technology is promising。”

In addition to working with the Wirtgen Group，The provincial high-speed development and construction company also has its own unique insistence in the field of technological innovation.。In order to create innovative enterprises with sustainable and high-quality development，The company was awarded the first batch of Heilongjiang Trading Group“Qu Bin Labor Model Innovation Studio”，Be responsible for improving the intelligent management and operation and maintenance level of equipment construction。

Trust each other，Witness the growth

“In addition to reliable equipment and innovative technology，Wittgen Group also attaches great importance to after-sales service.，I was very impressed with the quality and timeliness of the service.，What touches me most is whether it is within or outside the warranty period.，The quality of service is as good as ever.。”Being close to customers is the service concept that Wittgen Group has been practicing.，It is this tacit knowledge gained from years of experience in the industry.，It also boosts the provincial high-speed development and construction company to move forward quickly.。

With the continuous improvement of road construction and maintenance requirements in the future,，Qu Zong and the provincial high-speed development and construction company adhere to the concept of green and low carbon.、Exploration and application of new technologies，Undoubtedly, it has set an example for the development of the industry in the region.。

Wittgen Group's technological innovation and high-quality service in the field of road construction and maintenance，Also won the trust and support of more and more customers.。Future，I believe that under the guidance of General Qu.，The provincial high-speed development and construction company will be a strong transportation province.、Contribute more to the construction of a powerful country。Qu Zong and the provincial high-speed development and construction company also welcome colleagues from all over the country to visit Harbin for exchanges and cooperation.。
