Zusammenfassung:A road boundary stone is provided to improve the whole strength and stability of the boundary stone according to the formation of the cut surfaces at the corners of both ends of the stone. A road boundary stone has a square column shape and cut surfaces which are adjacent to the road boundary to be exposed, and formed at the corners of both ends of the front surface. A reflection unit is arranged at the cut surface. The cut surfaces are directly radiated by the head light of the vehicle and are slantly formed at the upper part of the front surface of the boundary stone to be exposed by the drivers. The cut surfaces are shaped like a triangle(10a), squares(10b,10c), and an inverse-trapezoid(10d).
