ROAD SURFACE COVERING SHEET AND ROAD SURFACE COVERING SHEET INSPECTION METHOD
To provide a road surface covering sheet that can be easily inspected after installation.SOLUTION: The road surface covering sheet 1 has: a laminate 2 in which three layers are laminated; and an adhesive layer 3 provided on one surface of the laminate 2. The laminate 2 is made of natural rubber and having, from the side furthest from the adhesive layer 3: a first layer 4 being colored black and having a thickness of 1 mm; a second layer 5 being colored green and having a thickness of 0.5 mm; and a third layer 6 being colored red and having a thickness of 0.5 mm. As the road surface covering sheet 1 installed on the road surface wears, the second layer 5 begins to appear on the surface. Thus, it is possible to detect that the residual thickness of the laminate 2 is 0.5 mm or more and 1 mm or less by detecting the green color of the road surface. It is possible to detect that the residual thickness of the laminate 2 is 0 mm or more and 0.5 mm or less by detecting the red color of the road surface as the third layer 6 begins to appear on the surface.SELECTED DRAWING: Figure 1
【課題】設置後の点検を容易に行うことができる路面被覆用シートを提供する。【解決手段】路面被覆用シート１は、３つの層が積層されてなる積層体２と、この積層体２の一方の面に設けられた接着層３を有する。積層体２は天然ゴムで形成され、接着層３から遠い側から順に、黒色に着色されて１ｍｍの厚みを有する第一層４と、緑色に着色されて０．５ｍｍの厚みを有する第二層５と、赤色に着色されて０．５ｍｍの厚みを有する第三層６を有する。路面に設置された路面被覆用シート１が摩耗するにつれて、表面に第二層５が現れると、路面の緑色を検出することにより、積層体２の残存厚が０．５ｍｍ以上１ｍｍ以下であることが検知できる。表面に第三層６が現れると、路面の赤色を検出することにより、積層体２の残存厚が０ｍｍ以上０．５ｍｍ以下であることが検知できる。【選択図】図１
