The present invention relates to a metal elastic bottom material burying an elastic pavement chip in an aluminum tube mold frame so that a walker walking in a trail can safely walk when it snows in the winter and also a hot wire cable for melting snow is mounted. The present invention comprises: a cylindrical tube which has a piece hole to connect side covers to an injected and molded aluminum bar and which has, in the aluminum bar, a cylinder tube for protecting hot wire and easily transferring heat; and a bracket connecting the bottom material in the lower end on left and right sides. The aluminum bar has an uneven shape. The elastic pavement chip is gradually buried in the mold frame formed so as to elastically respond even when the walker's load is applied. After the trail bottom material is installed, the hot wire is installed on right and left sides of the bottom material, and the conduit cover is fastened by a piece, if power is applied, the heat is transferred to the surface of the elastic bottom material to melt snow. |
