SUZHOU, China, Sept. 26, 2021 /PRNewswire/ -- XCMG (000425.SZ)
has deployed its unmanned road construction fleet to complete the
spreading and maintenance of the Suzhou Road segment of the
Nanjing-Shanghai Expressway, the busiest highway in China. As the largest scale unmanned road
construction fleet in the world, its successful application as an
integrated set solution is a landmark event of milestone
significance in the development of intelligent highway maintenance
and construction globally.
The Nanjing-Shanghai Expressway is one of the highest-class
highways in China and a golden
passage in the Yangtze River Delta. XCMG's unmanned fleet consisted
of 10 tandem road rollers and two large-width pavers, all under the
unified command of the BeiDou satellite positioning reference
station. Supported by technologies including the highly precise
BeiDou positioning, inertial navigation and obstacle recognition,
the fleet completed the scheduled tasks including driving, steering
and rolling compaction.
"This unmanned road maintenance and construction project allowed
us to reach the 'intelligent maintenance' stage. The inspection
pass rate is much higher than that of traditional manual
construction, and XCMG's unmanned technologies have excelled in
construction efficiency and control accuracy," said Li Xin, Assistant GM of Jiangsu Xiandai Road
& Bridge Co. Ltd..
XCMG has applied its unique and exclusive continuous asphalt
thickness measurement radar technology to this unmanned road
maintenance project, which is way ahead of the traditional core
measurement that continuously and accurately measures the
thickness of the paved asphalt without damage, reaching a maximum
depth of 120mm and guaranteeing a measurement error of ±1mm. The
technology provides an accurate basis for real-time control of the
paving thickness and improves paving accuracy and construction
quality.
The unmanned fleet has met all construction and maintenance
requirements through the grid format tests of thickness, compaction
and friction coefficient.
XCMG has always placed unmanned intelligent technology as a
research focus and successfully achieved normalized application on
the Panzhihua-Dali Expressway, Liuzhou-Nanning Expressway,
Beijing-Xiong'an Expressway and Beijing-Dezhou Expressway.
"In the future, XCMG will continue to commit to the R&D of
intelligent and unmanned products, truly achieving standardization
of unmanned engineering construction and reshaping highly complex
and difficult construction. With intelligent sensing and control,
digital construction and unmanned technology as the core, XCMG is
dedicated to providing customized, high-quality intelligent
solutions for customers," said Lige Xue, R&D Engineer of
XCMG.
