A temporary marking material comprises a thermally-expansible layer containing a binder, a pigment and thermally-expansible microballs, and a pavement marker comprises the temporary marking material. Both the temporary marking material and the pavement maker hardly peel off or move during the use, and when they become unnecessary, they can be easily peeled off by heating from the structure in a short time by virtue of the expanded microballs. When the temporary marking material is in practical use, the thermally-expansible layer is disposed on the surface of a structure. The pavement marker is disposed on the pavement as part of a surface of the structure. |
