Since the end of April，The first phase project of Xuanjing Expressway in Anhui Province has started the asphalt spreading operation.，SANY unmanned spreader compactor group is applied to the construction of bid sections 01 and 03 of the project at the same time.，The total working area has reached 30 kilometers.，At present, the operation of asphalt underlayer has been basically completed.，The spreading and pressing construction of the middle layer will be started one after another.。

During the construction in May，Unmanned presser groupHigh efficiency、Good qualityIts characteristics 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.。

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。

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.。

For the next two months,，Unmanned Pressing Machine Group Will Continue to Be Busy on Xuanjing Expressway。

Sanyi Road Machine will continue as before.，Deeply develop intellectualization、Research on Unmanned Construction Technology，Help the industry change，To contribute more to the development of new quality productivity in the field of intelligent construction。
