| Abstract: | The related research about the stabilized mixture of hydraulic fill sand and silt in coastal area were carried out,which included the study of optimum mixing ratio of hydraulic fill sand and silt and appropriate stabilizer type;compressive strength tests,splitting strength tests,wet and dry cycle tests and freezing and thawing cycle tests of the stabilized mixture of hydraulic fill sand and silt in the laboratory;on-site construction process of the stabilized mixture;the economic benefits comparative analysis of the stabilized mixture of hydraulic fill sand and silt and hillside stones.The results show that when silt and hydraulic fill sand were mixed with 40% and 60% of the mass and the G2 stabilizers were used to stabilize the silt and hydraulic fill sand mixture,the performances of the stabilized mixture were relative high;Both the on-site strength and deflection value could meet highway subgrade design criterion;the stabilized mixture of hydraulic fill sand and silt could replace hillside stones as subgrade filler,which could save 40.5% cost. |
| Keywords: | hydraulic fill sand silt stabilization highway subgrade hillside stones |
