Beijing, July 25 (Reporter Liu Zhiqiang) The reporter learned from the special press conference of the Ministry of Communications on the 25th: At present, the expressway network with the national expressway as the main body has covered 98.8% of the cities and places with a population of more than 200,000. The county-level administrative center connects about 88% of the country's county-level administrative regions and about 95% of the country's population; ordinary national highways basically cover the county-level and above administrative regions and border ports that are open all year round, effectively connecting important towns, industrial parks, transportation hubs and tourist attractions.

According to reports, the national highway network, including the national highway network and the ordinary national highway network, is the foundation and an important part of the main framework of the national comprehensive three-dimensional transportation network. By the end of 2021, 117,000 kilometers of national highways have been built, and 257,700 kilometers of ordinary national highways have been opened to traffic. The "National Highway Network Planning" jointly issued by the National Development and Reform Commission and the Ministry of Transport proposed that by 2035, the total scale of the national highway network will reach about 4,600 kilometers. The ordinary national road is 90,000 kilometers.

The meeting also introduced the high-quality development of rural roads. By the end of 2011, the total mileage of rural roads will increase from 3.564 million kilometers to 3.564 million kilometers by the end of 2021, with a net increase of more than 900,000 kilometers in 10 years.

In recent years, highway construction technology innovation has achieved fruitful results. Highway survey and design technologies represented by digital maps, geological remote sensing, computer-aided design and simulation, and the application of Beidou system have continued to improve; soft soil, loess, frozen soil, and desert highway construction technologies have continued to mature. Perfect; continuous breakthroughs in related technical equipment such as super-span bridges, super-long tunnels in mountainous areas, submarine immersed tunnels, and large-diameter shield tunnels. In the next step, relevant departments will, in accordance with the planned goals and tasks, start from the aspects of promoting the implementation of key projects, strengthening the coordination and connection with other modes of transportation, improving the green and intelligent level of highway construction, and promoting the safety and reliability of the highway facility network, and strive to promote modernization, Construction of high-quality national highway network.

The establishment of the national expressway network is inseparable from the the rapid impact compactor has remarkable compaction effects in highway subgrade compaction, bridge and culvert back compaction, and high fill compaction.
