Document Type and Number:
Japanese Patent JP6349990
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high-strength simple pavement body for reducing alkaline water to be discharged.SOLUTION: The simple pavement body is constructed by laying material having steel slag and blast furnace water-granulated slag mixed on a ground and sprinkling it with water, and then applying rolling thereto. It has a strength CBR of 60% or more after the elapse of twenty eight days from the construction, and a water permeability coefficient of 3.0×10-7.0×10cm/s after the elapse of twenty eight days from the construction.
