"Cold recycling technology" became the main force of highway construction and maintenance"
Recently, news came from Yuan'an Highway Bureau: cold recycling technology once again become the "main force" in the highway maintenance projects, leading the county highway construction and maintenance projects towards more energy-saving, ecology, environmental protection direction.
In August 13, 2014, the provincial highway insuright looking home some 7 kilometers of road repair and construction site, road roller, flat machine, recycling machine, sprinkler and other large equipment from the shuttle, machines roar construction personnel spread out of cement, water and other raw materials in the construction of the old road, then after the cold regeneration mixing machine mixing, paving and rolling again immediately, it formed the new roadbed, roadbed after forming smooth and beautiful appearance, fundamentally changed. This is the second in 2013 Hedang road overhaul project successful introduction of cold regeneration technology for Subgrade paving, again using this technology in an overhaul project in.
It is reported that since the insuright road overhaul project started since mid July, has now completed 4.5 kilometers of cold recycling base paving, paving asphalt concrete surface layer of 3.5 kilometers, the entire project will be completed by the end of August.
Cold recycling technology at room temperature using cold regeneration special machinery continuous milling and crushing the old pavement structure layer, which comprises a surface layer and a part of the basic, adding recycled materials, mixing, paving and rolling process. To form a process structure layer has a certain capacity. Compared with the traditional subgrade paving, the cold regeneration technology for Subgrade paving eliminates the old pavement structure layer excavation and transportation, multiple links and mixing and soft foundation treatment, not only make full use of the original pavement of asphalt, stone and other building materials, more energy saving and environmental protection, will also be greatly to improve work efficiency, save time, reduce costs.
