半刚性基层配合比设计与性能研究

Mixture Ratio Design and Performance of Semi-rigid Road Base

以实际工程建设为背景,基于不同种类集料、包含AGS在内的不同水泥品种、不同水泥掺量对于水泥稳定基层的强度进行了试验,验证了它们的工程可行性。利用正交试验分析了前述不同因素的影响大小,为配合比设计和质量控制提供了依据。依据试验结果提供了建议配合比,该配合比在工程中的应用表明其各项指标优良。

Based on road construction,numerous experiments were carried out to verify the strength of stable base course of cement,taking into account such consisting factors: various kinds of aggregates,different cement types including AGS,and the usage of cements.The engineering feasibility of mixtures was verified.The influence of various composing factors was analyzed with orthogonal tests,which provides evidence for the design of mixture ratio and quality control.The suggestive design was proposed according to preceding research.The engineering application was also very satisfactory.
