摘要
概述了当前国内外冷再生技术的发展及实施状况,并分析了目前冷再生技术所遇到的困难,结合青海独特的高寒干旱的大陆性高原气候及砂质土质条件分析道路基层冷再生可行性,分析了基层旧料混合沥青面层旧料冷再生形成基层的强度形成机理。结合青海目前公路建设及未来规划情况分析冷再生在青海公路建设过程中带来的经济效益。
The development and the implementation of cold regenerated technology at home and abroad was summarized, and the current difficulties were analyzed. In this paper, combining with unique cold continental plateau climate and sandy soil conditions of Qinghai, the feasibility of cold regenerated technology of highway base was discussed. Meanwhile, through cold regenerated technology, the base can be reformed by old asphalt mixture. And the strength formation mechanism is analyzed. In this paper, combining with the actual condition and the planning of highway construction of Qinghai, the economic benefit brought from cold regenerated technology during highway construction is analyzed.
