PROBLEM TO BE SOLVED: To prevent a line from being abraded by forming a scraped groove with a designated width over the entire surface of paved road, and laying a line material in the groove so as to be flush with the paved surface. SOLUTION: This flush line marking method is executed along highways, for instance, to prevent abrasion of lines due to snow removal which is peculiar to deep-snow districts. Further, scraped grooves with a designated width are formed in the surface of the road by a grooving machine, and a line material is laid in the grooves. Therefore, abrasion of the line material is alleviated, which extends the life of the roads and sectioning lines to a much longer period than the life of currently marked lines. Thus, wear rate of the line materials is extremely alleviated, and therefore the flush line marking method can be applied to the roads and the sectioning lines, to thereby play a role of energy saving. |
