风化泥岩作为路基填料的试验研究

Experimental Research on Mudstone Used as Roadbed Filling

南京绕越高速公路方山区域广泛分布风化泥岩,文章对该风化泥岩作为高速公路路基填料的问题进行研究。室内试验成果表明:泥岩开挖料具有遇水膨胀崩解和泥化特征,水稳定性差,但如采用橡皮膜包裹,则岩块试样浸水后完整性较好。

The mudstone widely exists in the Fangshan area of Nanjing,this paper analyses the problem of using mudstone as roadbed filling during the construction of the Rebounding expressway of Nanjing. The laboratory testing results show that mudstone materials show collapsed and mudded characteristics when meet water. While enwrapped by rubber membrane,the mudstone sample is integrity after immersion in water.
