PURPOSE:To improve visibility by arranging base materials, which have a round or oval bottom and a top surface of a specific diameter and a specific height and have glass beads of a specific refractive index and a specific granular diameter scattered on their surfaces, at specific intervals in the longtitudinal and cross directions of a road marking line. CONSTITUTION:A protruding base materials 2, which have a bottom face and a convex top face of round shape of about 17-30mm in diameter or of oval shape of 17-30mm long on their axis and is about 3-10mm high, are applied on a previously provided indication line with a mobile machine which melts a thermal fusible road marking material at 180 deg.C-200 deg.C and transcribes a specific amount of it on a road surface in a specific length of time. Immediately after that, transparent glass beads 1 of a granular diameter of 0.1-0.2mm and a refractive index of 1.5-2.2 times are scattered. Subsequently, the base materials 2 are arranged and provided at almost equal intervals of 25-100mm in the cross direction of the road marking line and rows of the base materials 2 in the cross direction are provided with almost same intervals of 60-250mm in the longtitudinal direction of the road marking line. Consequently, it is possible to thoroughly visualtize the road marking line even on a rainy day or at night. |
