Due to the advantages of lightweight,regulatability,and construction convenience in foam soil,it is increasingly widely used in highway road bases.During the rainy season,the water con-tent of road bases increased sharply,which led to changes in their mechanical properties.There-fore,the research on the characteristics of foam light soil water absorption characteristics is of great significance.Taking the improved bubble light soil as the research object,by controlling the water absorption time of the test block,comparing and analyzing different wet density,the same powder clay mixing,the same wet density,different powder clay mixing,and unlimited compres-sive strength changes with the water absorption time with the water absorption time.Relationship curve and stress strain curve.The test results show that the water absorption rate is rapidly in-creasing as the water absorption period is rapidly increasing,and then the trend of changes slowly,and it decreases with the increase of the amount of powder clay.The pressure strength decreases with the increase of the amount of powder clay,and increases with the increase of the density of humidity.
