摘　　要：介绍了高速公路填石路基施工工艺的适用情况,分析了不同填料石料对路基质量的影响,对高速公路填石路基施工工艺进行了详细论述,结合某山区高速公路试验路段,对碾压施工前后路基密度与压实度进行检测,结果表明,采用合适料源以及规范施工工艺进行高速公路路基施工,压实度满足工程要求。The application condition of construction technology for rockfill subgrade of expressway is introduced, the influence of different building stones of filling materials on the subgrade quality is analyzed, and the discussion on the construction technology for rockfill subgrade of expressway is made in detail. In combination with the trial pavement section of a mountain highway, the detection on the subgrade density and compactness before and after the rolling compaction construction is made. The results show that, the compactness can meet the engineering requirement by adopting suitable material sources and standard construction technology to perform the expressway subgrade construction.
