Study On Field Compaction Tests Of Coal Gangue Used As Filler Material Of Highway Embankment

In recent years,with the people's consciousness of environmental protection being strengthened day by day,the domestic and foreign experts and scholars attached great importance to the research of the comprehensive utilization about coal gangue,among which the topic of coal gangue used as the filler material of embankment is one of the hot topics.This paper experimented Crushed value,CBR, Expansion, Water absorption ratio and other physical and mechanical indicators of coal gangue of Huainan through laboratory tests.Based on the thirteen experimental section of Huainan Xihutong of He-Huai-Fu highway project, this paper has focused on the detailed research of field compaction tests, including the subsidence principle when coal gangue roadbed is compacted, the function of three kinds of RCC,best loose thickness and the RCC construction combination and so on.This paper has also carried out the research of the construction quality control methods for coal gangue embankment. In a word,this paper provided a scientific theory and some useful experience for the gangue roadbed construction.
