PROBLEM TO BE SOLVED: To provide a production method of a modified dredge soil that can modify dredge soil of a high moisture ratio using simple treatment equipment in short time, and can efficiently carry dredge soil after modification.SOLUTION: A production method of modified dredge soil includes: a solid liquid separation volume decreasing process in which dredge soil in which moisture ratio is at least 160 mass%, an electrolyte concentration of a liquid layer part is at least 1000 mg/L is mixed with a polymer flocculant to precipitate an aggregate, supernatant fluid is discharged, and a volume decreased aggregate is obtained; and a modification treatment process in which a solidification material is mixed to the volume decreased aggregate to modify the volume decreased aggregate. |
