| Abstract: | In order to reduce the uncertainty of the proper proportion among lime,fly ash and soil in the mixture design,and overcome the difficulties in quality control in the complex geological condition for road engineering,the mixture design and the filling method of road base in low-lying area with much water in north China were introduced.Then,the compressing test was conducted and the proper proportion was given.Finally,some measures to controll the quality of fill were proposed.Test results and the application in construction show that the mixture design and the quality control measures were proper. |
| Keywords: | road base fill mixture design quality control test |
