就地冷再生技术在公路工程中的应用

Application of Cold Recycling Technology in Highway Engineering

由于就地再冷技术能有效保护施工周围环境,所以该技术广泛运用于我国公路工程领域。本文通过实例,详细介绍了就地再生技术在施工中的所有关键工序,充分表明了该技术的可行性,对就地冷再生技术的经济效益及社会环境效益进行了深入分析,实践证明,就地冷再生技术优势突出,不仅施工工序简便,而且能节约20%~30%的费用,经济效益可观,有很好的发展前景。就地冷再生技术的应用不仅可以节约大量的资金,减轻环境污染,还对交通干扰小、改善路面级配、降低孔隙率、延缓路面老化,给我国旧沥青路面改建带来不可估量的经济效益和社会效益。

As the local cooling technology can effectively protect the surrounding environment,so the technology is widelyused in China＇s highway engineering. In this paper,all the key processes of in-situ regeneration technology are introduced in detailthrough examples. The feasibility of this technology is fully demonstrated. The economic benefits and social environmentalbenefits of in-situ cold regeneration technology are analyzed in depth. Practice has proved that The advantage of cold regenerationtechnology is outstanding,not only the construction process is simple,but also save 20%to 30%of the cost,considerable economicbenefits,good development prospects. In-situ cold regeneration technology can not only save a lot of money,reduce environmentalpollution,but also small traffic disturbance,improve road gradation,reduce porosity,delay the aging of the road,to our country＇s old asphalt pavement reconstruction brings immeasurable economic benefitsAnd social benefits.
