In line with revisions applicable to earthwork structures, a new selective method for slope protection has been announced. The selective method is applicable to various line sections of which varied physical conditions considered. The slope protection work that grades Level-1 shall provide a high degree of safety and usability. Simultaneously, the slope protection for a grade of Level-3 shall provide an erosion control function at least. The foregoing slope protection shall be applicable to various cut sections depending on their different physical conditions. In addition, three different types of flow-charts for cut sections as classified elsewhere intended for the ease in maintenance work.
