Document Type and Number:
Japanese Patent JP6823551
Kind Code:
B2
Abstract:
To provide a steel slag roadbed material that can keep low the hardening strength of a roadbed, and its construction method.SOLUTION: The roadbed material is partially or wholly composed of steel slag and includes a hydration reaction inhibitor composed of one or more kinds selected from sugar, carboxylic acid and organic acids other than carboxylic acid. Its construction method is to recover an existing steel slag roadbed material by excavating an existing roadbed, to crush and size the steel slag roadbed material, and then to add and mix the hydration reaction inhibitor composed of one or more kinds selected from sugar, carboxylic acid and organic acids other than carboxylic acid to the crushed and sized steel slag roadbed material when re-using it as a roadbed material. Since the steel slag roadbed material contains the hydration reaction inhibitor, the hardening strength of the roadbed can be kept low even after a long period of time has passed from the construction.SELECTED DRAWING: None
