高速公路路基膨胀土填料改性处理及应用

Modified processing of the roadbed expansive soil filler of the expressway and its application

膨胀土能否作为高速公路路基填料一直是个有争议的问题。本文在前人理论的基础上,对宁靖盐高速公路在施工中所遇到的膨胀土进行了一系列的改性处理试验,总结出膨胀土改性的具体办法,并对具体的施工技术作了相应的研究。

It is still in dispute that the expansive soil can be used as roadbed filler of the expressway On the basis of the former's theory,in accordance with used expansive soil during the construction of Ningjingyan expressway,we made a series of experiments in modified processing of filler,finding out concrete method for the modified processing,and making a study on the concrete know-how for the expansive soil in construction
