高速公路路基填料 CBR 试验值探析高速公路路基填料 CBR 试验值探析 摘要：近年来随着我国经济总量的提升，高速公路为我国的货物运输业提供了巨大帮助，然而由于设计施工人员综合素养偏低，或是公路所受车辆动力荷载较大，目前我国很多高速公路出现了不同程度的破坏。通过分析铜黄高速公路路基填料的 CBR 试验、颗粒分析试验、液塑限试验等试验结果，讨论了土体颗粒组成、矿物成分及含量等因素对路基填料 CBR 值的影响，并提出了有效的改善和优化措施，对于提高公路路基的强度及承载能力，保证高速公路的整体质量和安全具有重要的现实意义。 关键词：高速公路；路基填料；承载比；试验分析 Abstract: in recent years, along with the economy of the total amount of ascension, highway in China for goods transportation with a huge help, however, because design construction personnel comprehensive quality is low, or the highway by dynamic load vehicle larger, at present our country many highway appeared different degree of damage. Through the analysis of copper yellow freeway roadbed packing CBR test, granule analysis test, liquid plastic limit experiment test results, the study soil particle composition, mineral composition and content of factors such as subgrade filling CBR value influence, and put forward the effective improvement and optimization measures to improve the strength of the highway subgrade and carrying capacity, ensure highway the overall quality and safety has the important practical significance. Keywords: highways; and As subgrade filling; Bearing ratio; Test analysis 中图分类号：U412.36+6 文献标识码：A 文章编号： 1 引言 近年来随着我国经济总量的提升，高速公路为我国的货物运输业提供了巨大帮助，不仅缓解了铁路、航空以及轮船的货运压力，还保证了货物能够及时安全到达目的地。然而由于设计施工人员综合素养偏低，或是公路所受车辆动力荷载较大，目前我国很多高速公路出现了不同程度的破坏，比如路面、路基、路肩、边沟以及边坡防护工程出现裂缝、路基沉陷、翻浆等损害形式。路基是...
