Recently, the Ministry of Transport announced at a press conference held by the State Council Information Office that during the "15th Five-Year Plan" period, three backbone national highways, G219, G331 and G228, will be fully connected to create a "golden outer ring" around China's border and coastal areas. The total length of this
great outer ring is about 27,000 kilometers, which is equivalent to two-thirds of the circumference of the earth's equator, and most of the sections have been completed and opened to traffic; the construction task during the "15th Five-Year Plan" period is to construct and renovate about 7,400 kilometers, with an estimated total investment of about 370 billion yuan . At a time when the cement industry is worried about shrinking demand, this infrastructure investment from the national level is worth weighing.
From "one-way end" to "circular network", 370 billion yuan reshapes the road network
along the border and coastal areas. The "family background" of the three national highways has its own merits: the northern line G331 runs from Dandong, Liaoning to Altay, Xinjiang. Linking the hills of eastern Liaoning, Changbai Mountains, the Greater and Lesser Hinggan Mountains and the grasslands of Inner Mongolia, it is known as "the most beautiful border highway". The western route G219 runs from Kanas in Xinjiang to Dongxing in Guangxi, which is one of the highways with the highest average altitude in the world, with an altitude drop of more than 5000 meters, interlaced with snow mountains, grasslands, deserts and Gobi along the way; The eastern route, G228, is close to the coastline, linking all the core coastal ports into a chain. Wu Zhihua, deputy director of the Comprehensive Planning Department of
the Ministry of Transport, introduced that the "Golden Outer Ring" broke the past road network pattern along the border and coastal highways, which were independent and mostly at the end, and linked the northern border, w estern border and coastline into a complete closed loop with Dandong, Dongxing and Altay as the links, connecting hundreds of land routes in series. To upgrade the coastal road network along the border from "one-way end" to "circular network".
For the cement industry, more important than scenery is the engineering attributes: this is not a simple pavement, but to focus on getting through the cross-mountain and cross-sea sections.

only. The western border section has to face high altitude, permafrost, earthquake fault zone, avalanche and rockfall. The northern line has to withstand the Gobi sandstorm and huge temperature difference between day and night. The eastern route is to solve the salt spray corrosion of seawater and the settlement of soft soil foundation-the harsh geological conditions mean higher bridge-tunnel ratio, stronger structural engineering requirements, and higher cement consumption per unit mileage.
At present, Fuqing Donggang Bridge in Fujian Section of G228 has completed the closure of the southern half and the capping of the main tower of G331 Dajiucaijiangkou Bridge, which are the most intensive cross-mountain and cross-sea sections with cement consumption. The reconstruction mileage
of 7400 kilometers hides tens of millions of tons of cement orders
with an investment of 370 billion yuan, and the construction and reconstruction mileage of 7400 kilometers is about 50 million yuan per kilometer, which belongs to the medium and high intensity trunk highway investment. According to the calculation of cement consumption per unit mileage of new construction and reconstruction and expansion projects of ordinary national and provincial trunk highways, the cement consumption per kilometer of construction and reconstruction is usually between 4000 and 6000 tons. If considering the high ratio of bridge to tunnel in the western section and the increase of soft foundation treatment in the coastal section, the corresponding cement demand level of 7400 kilometers is between 30 million and 45 million tons. Even if it is divided equally according to the five-year construction period, it can contribute 6 million to 9 million tons of stable demand every year. In terms of structural distribution of
demand, G331 connects the northeast and northern border markets of Inner Mongolia, G219 passes through western markets such as Xinjiang, Xizang, Yunnan and Guangxi, and G228 passes through coastal provinces with large cement consumption such as Liaoning, Hebei, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong and Guangxi, which will benefit from the demand for cement in these regions.
