📋 Tender Overview
The roads in the village are now well built, making it more convenient and safer to go out. The economy and life are getting better, and the supporting facilities are also upgraded! Luo Gai, secretary of the Party Branch of Dangjiangrong Village, Duocai Township, Zhiduo County, Yushu Tibetan Autonomous Prefecture, Qinghai Province, sighed. On the Qinghai Plateau, with an average altitude of more than 4,000 meters, a rural and pastoral road renovation project with the keyword lowest cost, latest technology, and most suitable solution is quietly changing the lives of farmers and herdsmen - without the need to dig a large scale of sand and collect materials, only mixing and crushing with original gravel pavement materials, the cost is reduced to one-tenth of the traditional process, but it can bring the old appearance of more than 6,000 kilometers of rural roads into new shapes. The latest news from the reporter is that more than 2,000 kilometers of road renovation is expected to be completed this year. The poor roads are a stumbling block for farmers and herdsmens travel and rural and pastoral economic development. Sand and material extraction in traditional highway construction is very damaged and costly. In view of the special geographical environment of Qinghai Province, the Qinghai Provincial Department of Transportation has taken active actions, adhered to the principle of no damage is the best protection, and explored highway ecological construction technology suitable for special areas of the plateau. Highway ecological construction technology is a highway construction technology that focuses on the construction and maintenance of gravel pavements in rural roads in special areas of the plateau. It takes pavement regeneration technology as the core, covering the entire process of slope renovation, side ditches cleaning, backfill and repair of original pits on the roadside. Feng Haidong, director of the Rural Highway Management Department of Qinghai Provincial Highway Bureau, introduced that the new technology makes full use of existing gravel pavement materials, mixes them evenly and then rolls them into molding, minimizing the digging and material collection, meeting the road travel needs in rural and pastoral areas, while also achieving the new goals of cost reduction, low carbon and energy saving. In 2023, Qinghai selected 36 1,018-kilometer sections as pilot renovation projects, and used existing pavement materials to complete the milling, mixing and paving process of pavement materials on one-time, forming the Plateau Special Area Highway Ecological Construction Technology Version 1.0 Version; in 2024, 212 rural and village roads were selected in Sanjiangyuan area to apply this technology, and the addition of 4.5% cement, Bailigu, composite road surface enhancer and other methods were used to continuously improve the strength of the pavement, improve wear resistance, reduce sand and dust problems, and explore the Plateau Special Area Highway Ecological Construction Technology Version 2.0 Version. From Haixi to Yushu, from Guoluo to Huangnan, brand new roads connect the beautiful lives of farmers and herdsmen in more than 20 counties (cities) in Qinghai, injecting strong impetus into the economic development of rural and pastoral areas. In the past, we had bumpy gravel roads, and all kinds of water accumulated when it rained. Now the road has been repaired, effectively solving the safe travel problem of 4,400 people in 16 animal husbandry clubs in three established villages in Reshui Township, making 6,227 acres of soft gold, 217,700 (only) livestock and the No. 1 Tomb of Xuewei have become popular products for foreign tourists and merchants. Long Zhixiao, branch secretary and village chief of Zhamari Village, Dulan County, Haixi Mongolian and Tibetan Autonomous Prefecture, Qinghai Province. This year, we plan to implement 110 ecological construction technologies for special plateau areas, involving more than 2,000 kilometers of roads. All design work has been completed and construction will be fully started after the plan is issued. Feng Haidong said that in the next step, Qinghai will try to apply new construction methods such as asphalt surfaces, micro surfaces and paving thin layers of asphalt concrete on the gravel pavement after regeneration construction. These measures will improve the driving conditions of the road and promote the prosperity of the rural areas in Qinghai Province, rich by the road, and beautiful by the road, and provide strong guarantees for promoting the comprehensive revitalization of rural areas and common prosperity for farmers and herdsmen.
