| Abstract: | The lithology of red sandstone decides that it is a poor highway roadbed tilling. In this pa- per, based on Ruixun expressway, two kinds of red sandstone typical chemical components and structure composition proportion was studied in Jiangxi province. This paper further studied the influencing factors of water sensitivity of the red sandstone and the correlation experiment . Finally, this paper put forward improvement measures for the red sandstone roadbed performance. |
