煤矸石在道路基层材料中的应用

Discussion on Utility of Coal Gangue in Materials of Highway Bases

本文针对煤矸石的工程性质,简要论述了煤矸石作为道路基层材料的指标和煤矸石道路基层强度的形成机理;对石灰、水泥、石灰和粉煤灰稳定煤矸石性能进行了比较;并就煤矸石作为道路基层材料存在的问题,提出其在工程应用方面的注意事项。

Directed against engineering properties of the coal gangue, the paper discusses the indexes of the coal gangue as the highway base material and mechanism of the strength formation of the coal gangue highway hast ,gives the contrasts of coal gangues stabilized with lime,cement and lime and fly ash and deems. As to the problems of the coal gangue used in highway bases, the paper puts forward some noticing items in the engineering utilities of the coal gangue.
