Abstract
With the rapid development of China's high-spee-d railway construction, the material used for roadbed constr-uction, more and more, gravel soil is a kind of ideal material. Although the gravel soil as roadbed fil er has the advantages of high strength, good stability and many other advantages, but the present railway roadbed fil ing compaction standard of coarse grained soil compaction quality control only quail-tative indicators, the construction technology and detection method in the technical specification in subgrade constru-ction, but no specific requirements for the corresponding.The subgrade fil ing construction is difficult to effectively control the quality of compaction . this paper discussed the round gravel soil Roadbed construction technology and quality control testing.关键词
