TWO-LAYER CONCRETE PAVEMENT DEVICE AND PAVEMENT METHOD USING NORMAL CONCRETE AND HIGH-PERPORMANCE CONCRETE
The present invention relates to a method for reinforcing an assembly-type slope by using high-performance shotcrete and a reinforcing member, the method, after producing, at a batch plant, normal concrete having a compressive strength of 21-30 MPa and transporting the normal concrete to a construction site: forms a normal-strength shotcrete by mixing either fly ash or slag fine powder or low-grade mixed material in which fly ash or slag fine powder is mixed, in an increased fluidity state by mixing 20-40% of bubbles of the total volume; forms a high-performance shotcrete by mixing silica fumes and metakaolin or high-grade mixed material in which either silica fumes or metakaolin are mixed; and forms a color shotcrete by mixing coloring materials of iron oxide or carbon black, so as to sequentially construct an inner layer section, an outer layer section, and a surface layer section on the slope.
