Recently，CCTV News Channel《Live news room》Broadcast《Unmanned paver for highway construction》，This paper reports the innovative practice of Sany Group in the field of pavement construction in Anhui Province.。Located in Anhui, central China.，Its high-grade highway construction is ushering in an intelligent revolution.——UAV Group Construction Technology of Sany Group。

Since the end of April，This cutting-edge technology shines brilliantly in the first phase of Xuanjing Expressway Project in Anhui Province.。At present，Sany UAV group has completed the construction of the middle layer of the 01 and 03 bid sections of the project.，The total construction mileage has reached 80 kilometers.，It is expected to enter the upper layer construction in early August.。

During 3 consecutive months of construction，High efficiency of unmanned compactor group、The characteristics of good quality have been fully reflected.，Daily construction mileage up to 1.8 kilometers，Through comparative experiments，Construction flatness is superior to manual work，Highly recognized by customers。

The unmanned asphalt construction of Xuanjing Expressway has three prominent characteristics.：Achieve full delivery、Most complete application of technology、The whole line is unmanned.。

SANY

Achieve full delivery

The UAV group application of the 03 bid of Xuanjing Expressway has been completely separated from the R & D personnel of Sany.，It is operated completely independently by the technicians of Anhui Liju Group.。

This is the first time since Sany delivered the fourth national intelligent pressure machine group equipment to Liju Group in November 2023.，Another major milestone.，Prove that the SANY Unmanned Pressing Machine Group is no longer operated only by R & D personnel.“Precision instruments”，It becomes a product that can be delivered to customers for independent use.。

SANY

Most complete application of technology

Bid Section 01 of Xuanjing Expressway、In addition to the application of standard unmanned technology, the fleet of Section 03，It also carries the latest research and development of Sany.The paver assists in driving、The screed automatically extends and retracts、Roller Fused Welt、360 Active SafetyAnd a series of stand-alone intelligent systems.，Further reducing the number of auxiliary workers on site、The operation safety and that operation quality are improve。

SANY

The whole line is unmanned.

The first phase of Xuanjing Expressway is divided into three sections.，The whole line applies the unmanned paving and rolling machine group to carry out the paving and rolling operation of the asphalt pavement.。Lot 01、SANY unmanned spreading and pressing equipment shall be used for Bid Section 03.。

This time, Xuanjing Expressway fully applies unmanned spreading technology in all bid sections for normal construction.，Not only in the lead in the country，It also marks the unremitting efforts of colleagues in the past few years.，Unmanned pressure technology is no longer only demonstrated in various observation meetings.“Gimmick”，And began to really move towards industry applications.。

Future，Sany Unmanned Pressing Machine Group will continue to shine in the construction positions of major highways.，With its cutting-edge unmanned technology、Excellent spreading efficiency and precise control ability，Leading the Intelligent Revolution in Road Construction，It will become a beautiful scenic line in the future transportation infrastructure construction.。
