PROBLEM TO BE SOLVED : To provide a composition for manufacturing a soil solidified material capable of industrially effectively forming a soil solidified material layer having high stability to repeated temporary freezing on a ground surface. SOLUTION : There is provided a composition for manufacturing a soil solidified material containing a soil containing a soil particle having a particle diameter of 75 μm or more of 75 to 88 mass% and a soil particle having the particle diameter of less than 75 μm of 25 to 12 mass%, and a soil solidification material, and having the content of soil in a range of 3 to 10 pts.mass based on 1 pt.mass of the soil solidification material. Further, it is preferable to contain a natural fiber reinforcement material in a range of 0.1 to 1.0 pt.mass based on 1 pt.mass of the soil solidification material. There is also provided a composition for manufacturing a soil solidified material of which a soil is formed by mixing a coarse soil having the total component of a gravel fraction and a sand fraction of 80 mass% or more, and a fine soil having the total content of a silt fraction and a clay fraction of 25 mass% or more, with a mass ratio in the range of 80 : 20 to 30 : 70.
