In order to improve the durability and prolong the service life of the stabilized soil, the methods of curing stabilized soil in the mixture solution of sodium silicate, sodium sulfate and sodium hydroxide and in the saturated limewater were proposed based on the idea of improving the curing environment of stabilized soil. The unconfined compression strength test, dry-wet cycle test, freezing-thawing cycle test and scanning electron microscope(SEM) test were conducted to compare the two kinds of saline solution curing methods. The results showed that curing stabilized soil in the mixture solution of sodium silicate, sodium sulfate and sodium hydroxide or in the saturated limewater could improve the strength, the resistance of dry-wet circulation and freezing-thawing circulation; Considering the effect on improvement of strength and durability, curing in the mixture solution of sodium silicate, sodium sulfate and sodium hydroxide was better than curing in the saturated limewater; Microscopic structures showed that the two kinds of curing methods generated more dense gel material, increased the cohesion, reduced the porosity, and decreased the macropore of the stabilized soil.
