| Abstract: | The widening and reconstruction of old road has high technical and economic value on in- creasing the road grade and improving the structure of road network. Combined with the project exam- ple, the paper mainly introduces processing technology of subgrade and pavement and related matters needing attention in the design of old road widening, and analyzes the pavement drainage technology from two aspects, the strengthening of inspection wells and the road construction around inspection wells, which can provide references for the similar engineering. |
