Recently，The 12th Annual Conference of Maintenance and Management Branch of China Highway Society, an industry event in the field of highway maintenance in China, was held in Hangzhou, Zhejiang Province.，The annual meeting is jointly sponsored by the Maintenance and Management Branch of China Highway Society and Zhejiang Transportation Investment Group Co., Ltd.，TopconChina was invited to participate in this annual meeting and was commended.。

This annual meeting is based on“High quality service, high technology innovation and high speed development”As the theme，It has attracted more than 3000 experts from all over the country.、Leaders and colleagues gather together、Participate in the grand event together！The experts and leaders attending the annual meeting are mainly the former vice-minister of the Ministry of Transport.、Weng Mengyong, President of China Highway Society，Zhu Hehua, academician of Chinese Academy of Engineering，Former Director of Highway Bureau of the Ministry of Transport、Li Yanwu, President of Maintenance and Management Branch of China Highway Society，Doctoral supervisor of Beijing Jianzhu University、“Beijing scholar”Xu Shifa，Li Jian, Deputy Director of Maintenance and Communication Department of Ministry of Transport Highway Bureau，Member of the Party Group of Zhejiang Transportation Department、Shao Hong, Director of Provincial Highway and Transportation Management Center, etc.。

During the opening ceremony of the annual meeting，It reveals the innovative application cases of maintenance projects in China's highway industry in recent years, namely“Innovative Cases of Maintenance Engineering in Highway Industry”Award and Selection Result。“Innovative Cases of Maintenance Engineering in Highway Industry”It is selected on the basis of extensive solicitation for the national highway industry.，It represents the leading level of highway maintenance engineering technology development in China at the present stage.。

Topcon China and Jiangsu Expressway Engineering Maintenance Company、Jiangsu Caracal Intelligent Engineering Co., Ltd.G15 Shenhai Expressway（The construction section located in Jiangsu Province is also called Coastal Expressway.）3DVariable milling project，That is《Application of Millimeter Variable Milling System in Jiangsu Expressway Maintenance Project》It has been recognized by the experts of the judges and the industry leaders of the Highway Bureau of the Ministry of Transport.，It stands out from more than 180 entries.，And won the second prize。

Project award certificate of honor and medal

Mr. Chen Xin, General Manager of Topcom Greater China, presented the award on the stage.

During this annual meeting，A total of 51 well-known domestic experts made thematic reports during the annual meeting.，Communicate and discuss together“Innovation of Highway Maintenance Management Mode、Maintenance Technology and Management of Long Bridge and Tunnel、Exploration and Practice of Intelligent Maintenance Equipment”And other industry hot topics。

Zhu Hehua, academician of the Chinese Academy of Engineering, made the keynote report of the conference.

Academician Zhu is here《Connotation and Evaluation of Smart Tunnel》In the report，Combined with the background of digital transformation，The application and development of infrastructure intelligent service system are comprehensively explained.。In depth, the digitalization in intelligent construction is elaborated.、Supporting role in the realization of smart tunnel and smart city，Make it clear“Digital technology is the fundamental guarantee for the intelligence of complex infrastructure construction process.”，And pointe out sharply that our country is in that“Intelligence”In process“Lack of top-level design and overall planning、The innovation of system and mechanism is lagging behind.，In some places, the train of thought is unclear.、Signs of blind construction，It is urgent to strengthen guidance。”

Doctoral supervisor of Beijing Jianzhu University、

“Beijing scholar”Xu Shifa made the theme report of the conference.

Teacher Xu is here《Development and Application of Durable Cold-mixed Cold-laid Pavement Material for Road and Bridge》The report points out the dilemma of domestic pavement materials at the present stage.，At present, most of the bridge deck pavement materials used are high pollution, high energy consumption and serious diseases.、Short life asphalt based material，Typical pain points include：“Pushing”、“Crack”、“Peel off”、“Pothole”Etc。The polymer paving material developed by Mr. Xu is polymer concrete.RubberStone®Have“Combine hardness with softness、Stable and durable、Energy saving and environmental protection”And other notable features，If its dynamic stability can reach 58000 times/mm（70℃,1.0MPa），YesSMAMix 4800 times/mm（70℃,1.0MPa）More than 10 times，The anti-fatigue life is more than 6 times that of the traditional pouring type。

The high polymer paving material is a positive response to and realization of national advocacy.“A transportation power”And“Ping An Centennial Quality Project”An important carrier。It is worth pointing out that，RubberStone®It has won the second prize of National Science and Technology Progress Award.，The typical overlay thickness is usually not more than 4cm，In front of the long bridge deck pavement of key projects，Generally, there are higher technical requirements for the flatness of the lower bearing layer.，Combined with TopconSmoothRideSmooth variable control system（Including millimeter variable milling and variable paving）Can achieve excellent paving and long-life application effect。
