通过对大修工程中旧沥青路面冷再生基层设计方法、施工过程、质量评定等的探讨,寻求一种合理利用资源、节约资金、保护环境、改造旧路的新途径,具有重要的现实意义。当前,在公路建设中提高资源利用效率,注重公路建设与环境保护并举以及使公路发展与自然环境相和谐,是新时期公路建设的新理念,于是如何应用新技术、新材料、新工艺,增加公路建设的投资效益,已成为公路建设者越来越关注的问题。道路就地冷再生技术为科学经济地进行旧路改造提供了一种新途径。道路就地冷再生是国外80年代后期迅速发展起来的一门新技术,在国外被广泛地应用于旧路维修改造、升级中。在旧路维修改造中应用冷再生技术可大大简化施工工序,同时可节约材料、缩短工期、保护环境、节约成本、提高效益。
Through the discussion of the design method, construction process and quality assessment of the old asphalt pavement cold reclaimed grassland in the overhaul project, it is of great practical significance to seek a new way to make rational use of resources, save money, protect the environment and transform the old road. At present, it is a new concept of highway construction in the new era that how to improve the efficiency of resource utilization in highway construction, pay attention to the simultaneous development of highway construction and environmental protection and the harmony between highway development and the natural environment, and how to apply new technologies, new materials and new techniques to increase The investment benefit of highway construction has become a problem that highway builders pay more and more attention to. Cold on-site regeneration technology provides a new way for scientific and economical transformation of old roads. On-site cold regeneration is a new technology developed rapidly abroad in the late 1980s. It is widely used abroad to repair, upgrade and upgrade old roads. The application of cold regeneration technology in the old road maintenance and reformation can greatly simplify the construction process, meanwhile can save materials, shorten the construction period, protect the environment, save costs and increase benefits.
