| Abstract: | This paper introduces the improvement techniques of subgrade with Sand,Low Liquid and limit powder earth by adding lime,as well as the construction precautions and a few countermeasures to some technical problems.By application of such techniques,we have solved the problems of insufficient compaction of plain soil filled expressway subgrade and little bonding strength of subgrade earth which tends to cause loose and peeling results.We have also overcome the defects of unstable side slope and rain flooding. |

| Keywords: | expressway subgrade filling low liquid limit powder earth construction technique |
