水泥稳定土底基层施工技术在市政道路工程中的应用

Application of Cement Stabilized Soil Subbase Construction Technology in Municipal Road Engineering

摘要:

水泥稳定土底基层在市政道路工程中具有传递荷载、形成结构支撑及协调变形的作用,其施工质量直接影响路面的耐久性和行车舒适性。文章以某市政道路工程为例,分析原材料选取、碎石级配选择、配合比设计、集中拌合、摊铺碾压及养护等施工要点。工程结果表明,底基层的平均压实度为95.57%,超过93%的规范标准,表明该技术能够提升底基层的密实度与稳定性,可为后续面层施工提供稳固基础。

Abstract:

Cement stabilized soil subbase plays a role in transmitting loads, forming structural support, and coordinating deformation in municipal road engineering. Its construction quality directly affects the durability and driving comfort of the road surface. The article takes a municipal road project as an example to analyze the key construction points such as raw material selection, gravel grading selection, mix design, centralized mixing, paving and rolling, and maintenance. The engineering results show that the average compaction degree of the subgrade is 95.57%, exceeding the standard of 93%, indicating that this technology can improve the compactness and stability of the subgrade, and provide a stable foundation for subsequent surface construction.
