| Abstract: | In this paper the key technique issues in treatment of cavity under highway bridge approach transition slab by grouting,under the limited technological and the material conditions,was put forward and discussed,based on the condition analysis of the highway under construction.And,relatively economical grouting material ratio was determined,by laboratory material test.The feasible grouting technics and monitoring method was worked out by the field test.And the result of the field test approves the feasibility of the employed material and technology. |
| Keywords: | Expressway Cavity under bridge approach transition slab Grouting treatment Laboratory material test Field test |
