Recently, CCTV News Channel's "News Live Room" broadcast "Unmanned Paving Machines Used in Highway Construction", reporting on Sany Group's innovative practices in the field of road construction in Anhui Province. Located in central China, Anhui's high-grade highway construction is ushering in an intelligent revolution - Sany Group's drone swarm construction technology.Since the end of April, this cutting-edge technology has shined in the first phase of Anhui Xuanjing Expressway. At present, the Sany drone group has completed the middle surface construction of the project 01 and 03 sections, with a cumulative construction mileage of 80 kilometers. It is expected to enter the upper layer construction in early August.

During the three-month construction process, the high efficiency and good quality of the unmanned spreading machine group have been fully demonstrated, with a daily construction mileage of up to 1.8 kilometers. Through comparative experiments, the construction flatness is better than manual work, which has been highly recognized by customers.The unmanned asphalt construction of Xuanjing Expressway has three outstanding features: full delivery, the most comprehensive application of technology, and unmanned application along the entire line.Achieve full delivery

The drone swarm application of the Xuanjing Expressway Section 03 has been completely separated from Sany R&D personnel, and is fully independently operated by the technical staff of Anhui Liju Group.

This is another major milestone since Sany delivered the first set of National IV intelligent spreading and pressing machine group equipment in the country to Liju Group in November 2023, proving that Sany's unmanned spreading and pressing machine group is no longer a "precision instrument" that can only be operated by R&D personnel, but has become a product that can be delivered to customers for independent use.SANY

The most comprehensive technology application

In addition to the standard unmanned driving technology, the fleet of the 01 and 03 sections of Xuanjing Expressway is also equipped with a series of single-machine intelligent systems such as SANY's latest developed paver assisted driving, automatic extension and retraction of ironing plates, integrated edge-adhering of rollers, and 360 active safety, which further reduces the number of auxiliary workers on site and improves the safety and quality of operations.Unmanned application throughout the line

The first phase of Xuanjing Expressway is divided into three sections, and unmanned paving and compacting machines are used throughout the line for asphalt pavement paving and rolling operations. Sections 01 and 03 both use Sany unmanned paving and compacting equipment.

This time, Xuanjing Expressway fully applies unmanned paving and compacting technology for regular construction in all sections, which is not only leading in the country, but also indicates that through the unremitting efforts of peers in the past few years, unmanned paving and compacting technology is no longer just a "gimmick" that exists only in various observation meetings, but has begun to move towards industry application.In the future, Sany's unmanned road-laying compactors will continue to shine at the construction sites of major highways. With its cutting-edge unmanned technology, excellent road-laying efficiency and precise control capabilities, it will lead the intelligent revolution in the field of road construction and become a beautiful landscape in the future transportation infrastructure construction.
