水泥稳定砂砾基层属半刚性基层结构的工艺简单,施工方便,料源丰富,是目前我国公路上常用的一种结构型式。本文给出了此种结构的施工工艺流程图,并就影响其施工质量的几大要素(混合料拌合、现场摊铺、碾压时间的控制、接缝处理、养生、含水量和水泥掺量的控制)进行了全面的阐述,对工程施工有一定的指导意义。
Cement stabilized gravel base is a semi-rigid base structure of simple technology, convenient construction, rich material source, is currently a commonly used type of structure on our roads. In this paper, the flow chart of the construction process of this kind of structure is given, and the main factors affecting the construction quality (such as mixture mixing, on-site paving, rolling time control, seaming treatment, regimen, water content and cement admixture Volume control) conducted a comprehensive exposition, the construction of a certain degree of guiding significance.
