PROBLEM TO BE SOLVED: To manufacture an attention arousing type curb having a high visually recognizable effect or a curb capable of displaying an effect such as a fluidity resistance, skid resistance, crack resistance, watertightness, abrasion resistance or the like by a simple execution process at a low cost. SOLUTION: In automatic curber execution, an aggregate supply process, in which aggregate or aggregate precoated with a binder is arranged in a layer in thickness less than approximately two grain size and fed to the surface of at least a part of a curb body under an uncured state and a burying leveling process, in which the fed aggregate is pressed in and buried to the surface layer of the curb body under the uncured state so that a part is exposed, are conducted in the order in addition to a curb-body execution process in which the uncured material 4a of the curb body is molded and placed on an execution surface and the curb body is formed during a time when the uncured material 4a is extruded and supplied to forms 20 and extruded from the forms 20.
