Concave-convex modular surface tile

The invention provides a concave-convex modular surface tile, which comprises a plane blank body, a dry granule layer and a cover coat, wherein the dry granule layer is positioned on the plane blank body, and the cover coat is positioned on the dry granule layer; and a plurality of dry granules with different sizes are arrayed so as to form the dry granule layer. The dry granules with different sizes are arrayed so as to form the dry granule layer. The concave-convex modular surface tile can produce a concave-convex surface tile on the plane blank body, so as to achieve the purpose of saving die cost and time cost during the production process.
