On January 15, 2020, shaanxi zhongda machinery group co., ltd. and xi 'an zhongli asphalt co., ltd. held the signing ceremony of the strategic intention cooperation agreement at the headquarters of zhongda machinery group. The signing of the agreement marks a solid step forward for both sides to jointly build a brand of long life and high quality road construction, laying a solid foundation for the next step of close cooperation and market expansion.

On November 14, 2019, asphalt, chairman of cuhk machinery group, xi 'an, chairman of the force had an informal discussion with the senior management team, said it will join hands to give full play to both sides in the asphalt pavement materials and intelligent road equipment advantages, promote long life, high quality road construction, in order to speed up the construction of the traffic power contribution to a force.
On December 4, 2019, at China aviation city ” Yanliang national aviation technology industry base on the municipal road, da da machinery “ Four in one, iron partner ” The high modulus natural asphalt pavement paving operation was carried out, and the lower temperature in winter did not affect the pavement paving. Power DT2000 model “ Transformers ” Structure segregation resistance Paver, auxiliary 17 tons of seven amplitude double steel roller and 37 tons tyred roller compaction, in the case of low temperature, two machine used a machine to replace the whole section of paving, to effectively control the gradation segregation, temperature segregation and close-grained evenness segregation, successful spread out of the open roof, no longitudinal seam and the road surface smooth level off, solves the problem of municipal road construction for many years, the present experts and leadership's consistent high praise, made a model for improving the quality of municipal road engineering, rewrite the history of the municipal road construction using traditional Paver.
For a long time, restricted by the construction conditions, construction environment and other factors, municipal road is the use of traditional Paver and paved, there are more common segregation, temperature segregation, density segregation, seriously affected the pavement service life. Long-term commitment to improve the quality of road paving cuhk mechanical and xi 'an to cooperate the force, the best road construction equipment and the best combination to improve the service life of road asphalt material, get the support of the project owner, supervision and conTractors, in cuhk mechanical innovation method + the paving segregation resistance force high modulus of natural asphalt AC - 20, has successfully completed in the municipal road construction technology research, has obtained the remarkable effect.
As the only research and development center of highway construction and maintenance intelligent equipment transportation industry in shaanxi province, zhongda machinery has been committed to it for 22 years. Scientific and technological innovation of intelligent equipment solves the problem of road construction and promotes the reform of construction method to promote the revolution of engineering quality ” In this paper, we have developed 6 series of road constructors, such as modern anti-segregation paver and super-large vibration force intelligent directional vibration roller, which have overcome the two major worldwide problems of pavement pavement segregation and subgrade anti-settlement compaction, and ended the history of relying on imported paver and paving.
Xi 'an zhongli asphalt company is a high and new technology enterprise integrating asphalt material trade, product deep processing and new material technology research and development. In recent years, they learn from foreign advanced experience, imported high-quality natural asphalt raw materials, patent technology to achieve the natural asphalt ldquo; Liquefaction & throughout; & other; Activation & throughout; To give full play to the good properties of natural asphalt and apply it to road construction.
It is proved by theory and practice. Subgrade compaction + segregation resistance paving + mixed material good ” To ensure the long life of the completed road surface. In order to ensure the pavement to reach 15 years and more than 15 years of service life, it is necessary to carry out road material innovation, road construction equipment innovation and construction method innovation. As two high-tech enterprises committed to improving the durability of road use and the research of long life, it is of great significance for cuhk machinery and xi 'an zhongli to share scientific research results and jointly promote technology. The two sides agreed to make full use of the advantages of anti-segregation and compaction of zhongda machinery, give full play to the good performance of natural asphalt, achieve in-depth cooperation, and work together to achieve the goal of road service life of 20 years, even 30 years, to build high-quality, long-life roads.
