| Abstract: | Studies show that improved sandstone used as subgrade material can largely improve it＇s physical and engineering properties,also strengthen the durability of the subgrade.Based on the unconfined compressive strength of disintergraded muddy sandstone,this thesis mainly studies the influence of different cement adding quantity to it,and put forwards better cement adding quantity on improving the open-air disintergraded muddy sandstone. |

| Keywords: | disintergraded sandstone subgrade the unconfined compressive strength |
