Zusammenfassung:	The present invention relates to a concrete pavement construction method using foam shotcrete, including the steps of: producing normal concrete having compressive strength of 21 to 30 MPa by a batch plant and transferring it to a site; putting bubbles of 20 to 40% relative to a volume into the concrete to improve the liquidity; and mixing the concrete with low-grade mixed material containing at least one among fly ash, fine slag powder, and stone dust to produce shotcrete of normal strength; and mixing the shotcrete with a high-grade mixed material containing at least one among silica fume, meta-kaolin, latex, polymer, and a coloring material to produce and pave high-performance shotcrete, thereby reducing the construction costs and securing the high strength and durability for convenient maintenance.
