Construction method for cement stabilized macadam base of expressway
The invention discloses a construction method for a cement stabilized macadam base of an expressway, and relates to the technical field of road construction. The highway cement stabilized macadam base construction method is used for super-thick cement stabilized macadam base construction and comprises the steps that materials are determined, the materials comprise cement, coarse aggregate and fine aggregate, and the fine aggregate is a mixture with textures on the surface; the mix proportion is determined, and the mix proportion is determined through a vibration forming experiment; site construction is conducted, specifically, the site construction is completed through one-time paving, rolling and curing in sequence; and checking and accepting, monitoring main quality indexes of site construction, and performing variability analysis on the collected data to obtain the variability. The problem of layering caused by layered construction of the super-thick cement stabilized macadam base is solved, the structural strength of the super-thick cement stabilized macadam base is improved, and the situation of pavement cracking is reduced.
本发明公开了一种高速公路水泥稳定碎石基层施工方法，涉及道路施工技术领域。本发明的高速公路水泥稳定碎石基层施工方法，用于超厚水泥稳定碎石基层施工，包括：确定材料，所述材料包括水泥、粗集料和细集料，所述细集料为表面具有纹理的混合料；确定配合比，通过振动成型实验，确定所述配合比；现场施工，依次经过一次性摊铺、碾压、养生完成现场施工；验收，对现场施工的主要质量指标进行监测，并将采集的数据进行变异性分析，以获得所述变异性大小。本发明解决超厚水泥稳定碎石基层采用分层施工造成的分层情况，提高了超厚水泥稳定碎石基层的结构强度，减少了路面开裂的情况。
