PROBLEM TO BE SOLVED: To continuously lay accurate button-shaped protrusions on a road surface in a short time. SOLUTION: A protrusion formation sheet previously forming a number of the protrusions on the surface with paint is prepared. A protrusion execution machine attaching at least a protrusion set rotor rotating in parallel to the road surface, a sheet heating burner and a line heating burner is used, after the protrusion formation sheet is supplied on the protrusion set rotor rotated and controlled in response to the moving distance of the protrusion execution machine in a fitted state, it is heated with the sheet heating burner, and laid on to be transferred on a band-like line heated with the line heating burner. |
