Recently, XCMG foamed bitumen in-situ cold recycling technology was successfully put into use on the national highway Zhengyang line G239 in Xinzhou, Shanxi. This economical, environmentally friendly and efficient sustainable road maintenance technology is the first successful application of domestic cold recycling equipment in this field.

At the construction site of Xinzhou National Road in Shanxi, XCMG XLZ2305K cold recycling machine is under intense construction. The equipment has a large power reserve, a powerful milling power and a recycling width of 2.3 meters, the mixture is mixed evenly, and the operation walking can reach 6-8m/min, and the construction is stable and efficient.

The most concerned by the construction party is also the decisive role in the foamed asphalt construction. It is the asphalt and water flow control technology in XLZ2305K. The foamed asphalt technology has almost strict requirements for the mixing ratio of asphalt and water. The reclaimed road section after construction has a good effect. The reclaimed pavement was cored after 3 days of health maintenance, and the expected effect was achieved, which was recognized and praised by users.

As of the end of 2019, the total mileage of national highways reached 5.0125 million kilometers. While rapid development, traditional road maintenance models are also facing severe challenges.

As a key technology that can realize asphalt pavement regeneration at one time, foamed asphalt cold recycling technology can provide excellent solutions to road maintenance problems such as shortage of asphalt resources and difficult disposal of road construction and maintenance waste, making it possible to "long life" pavement .

Due to the huge equipment of the cold recycling machine, strict technical requirements for the complete machine, and long development cycle, my country has long relied on imported equipment. However, foreign technical blockades have caused expensive equipment and severely restricted the application of foam cold recycling technology in China.

To seize the new opportunities in the era of large-scale highway maintenance and demonstrate the responsibility and responsibility of the “national weapon”, XCMG began to study foamed asphalt in-situ recycling technology in 2014.

Behind the core technology research of domestic cold recycling equipment and the breakthrough in the application field are the industrial accumulation of XCMG cold recycling machines for more than 20 years.

XCMG has a complete product line of recycling equipment, which can provide different technologies for high-grade highways, national and provincial trunk lines, rural roads and other different levels of road maintenance, including cement in-situ cold recycling, foamed asphalt, and emulsified asphalt. application. This is not only the rapid development of XCMG products and technology, but also the rapid take-off of the national manufacturing strength!

Starting from scratch and starting from scratch, it has overcome the three major technical difficulties of "foaming device", "asphalt loop electric heating", and "automatic flow control". It took 6 years to break industry barriers and technical blockades of foreign brands, and finally settled in Shanxi. Xinzhou played triumphantly.

As a national cold recycling machinery brand, XCMG actively implements an innovation-driven development strategy. It uses "Made in China 2025" as a starting point to promote technical problems. It has an economical, efficient and environmentally friendly road maintenance technology led by "foamed asphalt in-situ recycling" We have gained a lot from the craftsmanship, laying a solid foundation for better serving the road construction and maintenance of the motherland!
