SHEET MATERIAL FOR DISPLAYING TWO LAYER STRUCTURE ROAD SURFACE

摘要

PURPOSE: To obtain a road surface indication sheet having excellent non-peel-off performance by a base sheet consisting of an upper layer embedded with glass beads and a lower layer having a predetermined hardness and a recovery. CONSTITUTION: Part of glass beads 5 are exposed and embedded in the upper layer 1 of a base sheet A consisting of rubber, a synthetic resin or the like and the lower layer 2 has a hardness of 30 deg. to 75 deg. and a recovery rate of 50% or below thereby obtaining a road surface indication sheet member of two-layer construction. This provides an excellent sheet member which does not peel off from the road surface.
