PURPOSE: A reinforced earth retaining wall system of the road is provided to secure the full tensile strength of a stiffener by using a steel reinforcement as the stiffener and to largely improve the pull-out force by an attachment coefficient of a back-filling body and the stiffener by combining a prefabricated projection with the stiffener. CONSTITUTION: A reinforced earth retaining wall system of the road is composed of a block body(80), a stiffener, a prefabricated projection, and a connecting device. The block body includes a vertical surface(72) formed at one side of a block body unit(71); an arc-shape surface(73) arranged at the other side of the block body unit and formed in an arc or an elliptical shape; a vertical groove(78) formed at the vertical surface to use a front plate; a D-shape groove(74) of which the center is penetrated, formed to the block body unit; a plurality of square projections(75) formed at the arc-shape surface of the block body unit and protruded upward in a double line; groove units(76) formed between the square projections; a lower protruded part protruded at the lower part of the vertical surface; and a placing unit(77) connected adjacently to the surface of the D-shape groove. The stiffener is horizontally constructed in the rear of the block body by using deformed bars, formed with threads at the side, and galvanized. A plurality of projections longitudinally combined to the rear of the stiffener in a conical shape include a combining groove unit to an upper body and an upper protruded unit to a lower body, and cover the outside of the stiffener. The connecting device is combined with the threads of the stiffener, placed and fixed to the groove unit of the block body, and formed with threads at the inside.
