摘　　要：国内对煤矸石作为路基填料及路面基层集料的研究成果与工程实例表明 :尽管煤矸石存在颗粒级配缺陷与水稳性差的特性 ,但只要掺入一定量的细颗粒 ,充分的压密与土质包边 ,煤矸石仍能作为路堤填料 ;未风化煤矸石具有与粉煤灰相似的化学活性成份 ,参入一定量的粉煤灰、石灰 ,能作为高等公路路面基层材料。In this thesis, the research achievements and examples of the coal gangue, used as roadbed filling and granular material of road base, are reviewed. It is indicated that although some of coal gangue is lack of some granularity and water stability, it can be used as roadbed filling once it is mixed with some of fine grain, compacted enough and wrapped in cohesive soil. The chemical activity of the component of un?weathered coal gangue is similar to fly ash, and if mixing with fly ash and lime it can be used as the road base material of expressways.
