In March 2012, a 600-horsepower WR2300L pavement cold recycling machine produced by our company was used for pavement cold recycling construction on S325 Provincial Road in Changge City, Henan Province. This section is a provincial road with a surface layer of 6-7 cm of asphalt concrete. The stabilization layer is a cement crushed stone stabilization layer. The owner's overhaul requirements for this road section are to mill and transport the asphalt surface layer using a milling machine, and then use a cold recycling machine to perform in-situ cold recycling on the cement stabilized soil base below. Under the careful organization of construction, the quality of a WR2300L pavement cold recycling construction produced by our company is stable and has been well received by the owner. The comprehensive evaluation is better than similar foreign models in another bidding section. In the later stage of construction, the owner only has one company WR2300L cold recycling machine construction work, and promised to continue to use our company's WR2300L road cold recycling machine in future projects. The praise of domestic road construction units in actual pavement cold recycling construction has greatly encouraged our company's employees. This is the result of our company's years of hard work to catch up with the performance of pavement cold recycling machines of foreign advanced companies. This is my The company's goals for many years, and now this goal has been partially achieved. The performance of advanced foreign machines is not impossible for domestic manufacturers. At present, the 600-horsepower cold recycling machine produced by our company is in the comprehensive construction efficiency of the machine and the accuracy of water injection measurement. , Milling drum wear resistance has been at the domestic leading level. We are convinced that hard work can get a return on progress, and we will continue to work hard to develop more advanced models, work hard to return users and society.
