Specifically, using a guide member or the like, the phosphorescent indicating member 2 is arranged at a predetermined position of the base layer 4, and the surface of the phosphorescent indicating member 2 is smooth with the resin mortar surface as shown in FIG. The phosphorescent marking member 2 is embedded so as to be (S105). At this time, the resin mortar around the edge of the phosphorescent indicating member 2 is raised by 0.5 mm to 1 mm and finished. Thereby, while reducing the load, such as an impact and friction at the time of a vehicle passing, with respect to the small edge of the luminous indication member 2, it is possible to prevent the passage of pedestrians and the like.

  Similarly, the release paper of the retroreflective display sheet 3 is peeled off, and the retroreflective display sheet 3 is attached to a predetermined position of the base layer 4 using a guide. At this time, a predetermined tool is used so that no bubbles remain between the base layer 4 and the retroreflective display sheet 3, and the surface of the base layer 4 is lowered by about 0.3 mm to 1.0 mm. The member is embedded in (S106). Further, the resin mortar around the edge of the retroreflective display sheet 3 is raised by about 0.5 mm to 1 mm and finished. Thereby, it is possible to reduce a load such as an impact and a friction when the vehicle passes with respect to the small edge of the phosphorescent indication member 2 and to prevent a pedestrian or the like from being obstructed.

  Thereafter, before the base layer 4 is cured, the masking material and joint frame material are removed, and the process waits until the base layer 4 is cured. After confirming that the underlayer 4 is cured, the outer edge of the underlayer 4 is masked with a cloth gum tape or the like, and a coating material is applied to the surface of the phosphorescent indication member 2, the retroreflective display sheet 3, and the underlayer 4 The coat layer 6 is formed to cover the phosphorescent indication member 2 and the retroreflective display sheet 3 (S107). A coating material mixes and stirs a predetermined hardening | curing agent with MMA resin mortar, and applies it uniformly on the surface using roller eyelashes. In this embodiment, the coating material has a standard application amount of 0.1 kg for one place.

  Next, before the top coat layer 6 is cured, the non-slip aggregate 6a is sprayed on the surface and adhered to the top coat layer 6 (S108). After spraying the non-slip aggregate 6a, a curing material such as a masking material is removed (S109), and the process waits until the top coat layer 6 is cured.

  After that, confirmation of the hardening of the top coat layer 6 and confirmation of the state of fixation of the outer peripheral edge of the phosphorescent indicating member 2 and the retroreflective display sheet 3 are performed (S110). If the fixed state is normal, then the equipment is cleaned up, the post-construction cleaning, etc. are finished, the work allowing the opening of traffic is performed, and the laying work is finished.
