According to the present invention, a road boundary stone made from recycled plastic comprises: a key groove formed to be longitudinally dented on the lower side of one longitudinal side of the road boundary stone; side holding grooves formed to be longitudinally dented on the upper and the lower side of the other longitudinal side of the road boundary stone; and a ground holding groove having a space part and holding protrusions, wherein the space part is formed to be longitudinally dented on the longitudinal lower side of the road boundary stone and the holding protrusions facing each other protrude from both ends of the space part. According to the present invention, the road boundary stone is manufactured with the recycled plastic so that production costs for the road boundary stone is reduced, the weight of the road boundary stone is small so that the road boundary stone being constructed can be smoothly transported and installed, and certain elasticity in the road boundary stone can absorb external shocks so that the road boundary stone is easily maintained with the low frequency of breakage or damage. |
