Highway cement concrete pavement construction technology includes five major processes and technologies: slipform paving cement concrete pavement technology and new technology for high-grade highways, new technology for track paving cement concrete pavement for primary and secondary roads; The new construction technology of the three-axis shaft unit of the second-level and below-level highways, and the construction technology of manual and small-sized machines for the third- and fourth-grade roads and rural roads. Among them, the first three are large mechanized construction techniques and new technologies, and the latter two are small mechanical construction techniques.
According to reports, the promotion of new technology and new technology of slipform paving has made the construction of high-quality cement concrete pavement of highways in China have advanced and reliable technical support. It marks that the construction technology of highway cement concrete pavement in China has entered and developed. The country is on the same stage as the international leader.
Since the Ministry of Communications issued the "Technical Specifications for Highway Cement Concrete Pavement Construction" in 2003, China's highway cement concrete pavement has soared from 167,000 kilometers in 2002 to 367,000 kilometers at the end of 2005.
It is understood that with the development of the world's largest highway infrastructure in China, the expressway will grow at an average annual speed of about 5,000 kilometers. At the same time, mountainous high-grade highway construction technology, special environment and complex geological conditions Under the highway construction technology, environmental protection, landscape road construction technology, world-class long-span bridge construction technology, special tunnel construction technology, traffic monitoring and charging technology, intelligent transportation technology, road maintenance technology, etc., also have a qualitative leap, Formed a technical system with Chinese characteristics.
