| Abstract: | Firstly,the usual defects among the many roadbed widening projects is analysed,and then,the reason is found out for the breakage of road surface fabric which infected by the asynchronous distortion and the difference of settlement of new and old roadbed,finally,this result is confirmed by the field testing on the project of roadbed widening in chongqing. |

| Keywords: | widening of roadbed asynchronous distortion instability settlement |
