Abstract:
PURPOSE: A road lining material is provided to have excellent construct ability due to a light dead load, and to overcome environmental problems which are caused by corrosion of a steel material and the aesthetic problems in a downtown area. CONSTITUTION: A road lining material comprises a main body (10) and a surface layer (20). The main body is composed of a rectangular hollow panel shape which integrally connects a lower plate (11), an upper plate (12), a left side plate (13), and a right side plate (14). The main body is composed of a fiber reinforced plastic. The left and the light side plate are extended from the upper plate, and composed of grooves on the surface layer The surface layer is composed of light concrete or plastic concrete. The aggregate of concrete is exposed to the surface of the surface layer, and composed of bumps.
