Recently, XCMG foam asphalt in-situ cold recycling technology has been successfully put into use on the national highway G239 in Xinzhou, Shanxi Province. This economical and environmentally friendly sustainable road maintenance technology is the first successful application of domestically produced cold recycling equipment in this field.

New Technologies Make Chinese Roads Longer in Life

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

Project Overview

What the construction company pays more attention to is the asphalt and water flow control technology in XLZ2305K, which also plays a decisive role in the construction of foam asphalt. The foam asphalt process has almost strict requirements on the mix ratio of asphalt and water. The recycled road section after construction has shown good results. After 3 days of health preservation, the recycled road surface was cored, achieving the expected results and receiving recognition and praise from users.

Construction site

As of the end of 2019, the total length of highways in China reached 5.0125 million kilometers. While developing rapidly, the traditional road maintenance model is also facing severe challenges.

As a key technology that can realize asphalt pavement recycling at one time, foam asphalt cold recycling technology can provide better solutions to pavement maintenance problems such as tight asphalt resources and difficult disposal of road construction and maintenance wastes, making "long-life" pavement possible.

Breaking through difficulties to strengthen the tendons and bones of asphalt roads

Due to the large number of cold regeneration equipment, strict technical requirements for the whole machine, and long development cycle, China has long relied on imported equipment. However, the foreign technology blockade has led to the high price of equipment, which severely limits the application of foam cold regeneration technology in China.

Seizing the new opportunity in the era of large-scale highway maintenance, and highlighting the responsibility and responsibility of "the national key", XCMG began to study the in-situ recycling technology of foam asphalt in 2014.

Construction site

Behind the core technology research and breakthroughs in the application field of domestic cold regeneration equipment are the industrial accumulation of XCMG's cold regeneration machine for more than 20 years.

XCMG has a complete product line of recycling equipment, which can provide different technical applications, including on-site cold recycling of cement, foam asphalt and emulsified asphalt, for the maintenance of high-grade highways, national and provincial trunk lines, rural roads and other roads of different levels. This is not only the rapid development of XCMG's products and technology, but also the rapid takeoff of the country's manufacturing strength!

Construction site

Starting from scratch, he successively overcame three major technical difficulties: "foaming device", "asphalt circuit electric heating", and "flow automatic control". In six years, he broke through industry barriers and foreign brand technology blockades, and finally achieved victory in Xinzhou, Shanxi.

As a national brand of cold recycling machinery, XCMG actively implements the innovation driven development strategy, takes "Made in China 2025" as the starting point to promote the solution of technical problems, and gains a lot in the new road maintenance process with economic and environmental protection led by "foam asphalt in-situ recycling" technology, laying a solid foundation for better serving the road construction and maintenance cause of the motherland!
