The development of road machinery is closely related to the development of new technologies, new techniques, and new materials for road construction. The two complement each other and are constantly developing. From the 1960s to the 1970s, the main characteristic of the development of foreign road machinery was large-scale. By the early 1980s, various road machinery had formed a series of products with complete specifications. After that, although new models appeared from time to time. But the main development feature is the continuous improvement and enhancement of the partial components of the existing machinery. It is mainly manifested in the extensive use of hydraulic transmission technology and electronic technology to realize the integration of mechatronics and hydraulics, improve the degree of automation control, improve mechanical operation performance and comfort, improve construction quality, and reduce environmental pollution.
The road construction industry is difficult, dirty, dangerous, etc. (called the 3K phenomenon in foreign countries) because of its engineering particularity, and has gradually become an unattractive industry. Coupled with the aging of the original road construction workers and the reduction of skilled workers, many difficulties have appeared in the development of the industry. In order to change this situation, each group pays more attention to the automation and intelligence of road machinery. This is mainly manifested in the widespread use of laser, ultrasound and other non-contact sensing technologies and computer technologies to make the operation more labor-saving, easier and more comfortable. Not only the large-scale machinery realizes automatic control, but also the small-scale machinery realizes automation, and the random quality automatic detection control system is added, which can not only ensure the quality of the project, but also improve the construction efficiency.
