高原地区道路冷补沥青修复材料性能研究与应用

Research&Applicationof Cold Patch Asphalt Materials of Roadsin Plateau Areas

通过对冷补沥青修复材料的工作机理进行分析,选择2种沥青冷补剂进行室内配合比设计,将确定的冷补沥青修复材料在高原环境下实际应用,经现场铺筑试验和修复效果检测并与室内试验进行对比,提出了高原地区冷补沥青修复材料的适用要求和范围,在此基础上优化了冷补沥青修复材料的设计方法,为其在高原地区使用提供了科学依据。

By analyzing the working mechanism of the cold patch asphalt materials,two types of cold patch agents were chosen for indoor mix design.The determined cold patch asphalt material was applied in plateau environments.After on-site paving,repair effect testing and compared with indoor experiments,the applicable requirements and the scope were proposed.Based on this,the design concept of cold patch asphalt materials was further optimized to provide a scientific basis for the implementation in plateau areas.
