随着我国城市建设的高速发展,城市化进程的加快,市政道路项目投资大幅增长。HAS固化剂稳定碎石道路基层,与传统水泥稳定碎石基层相对,具有更好的和易性,更宽的含水率限制,含泥量的要求低(20%以下),且干缩小,裂纹少,强度有保证、使用寿命长,正在市政项目,尤其是高标准道路基层中逐步推广。但目前施工案例少,工艺不成熟,HAS固化剂稳定碎石层所有技术标准均参照水泥稳定碎石执行,本文以实际工程为例,根据实践总结HAS固化剂稳定碎石施工工艺及质量控制要点,为今后HAS固化剂稳定碎石施工提供参考。
With the rapid development of urban construction in China and the acceleration of urbanization, the investment in municipal road projects has risen sharply. HAS curing agent Stabilized gravel road base, with the traditional cement stabilized macadam base relative, with better workability, a wider moisture content limit, low clay content requirements (20%), and dry shrinkage, cracks Fewer, strength is guaranteed, long service life, is being gradually promoted in municipal projects, especially in the grassroots level of high standards. However, at present, there are few cases of construction and immature technology. All technical standards for the stabilized macadam layer of HAS curing agent are implemented with reference to cement stabilized macadam. Based on the actual project, this paper summarized the construction process and quality control points of stabilized macadam , Provide a reference for the future HAS curing agent stable gravel construction.
