A dry construction method of a curb is provided to have quick construction speed and to reduce the manufacturing cost by constructing the curb right after pouring the concrete. A dry construction method of a curb comprises: a step of forming a base layer for the construction of the curb(S100); a step of forming a side ditch by pouring the concrete into a both tip of a retreated groove part with having a little room with a direct pouring method without a mold; a step of constructing the curb in the side ditch(S300); a step of filling up the retreated groove part at the same time with arranging the curb and the side ditch with a high-vibration compacting machine once the curb is put on the retreated groove part of the side ditch(S400); and a step of fixing the curb by pouring mortar between the retreated groove part and the curb(S500).
