Description of the Related Art As is well known in the art, lane marks such as painted white lines and yellow lines are generally used in roadways as road stop lines, pedestrian crossings, and character displays. Conventionally, these lane marks have to be paved on the road with asphalt, concrete, interlocking, concrete slabs, etc., and then apply the paint to the paved surface, such as car stop lines, pedestrian crossings, character display, division pairs etc. It was generally formed by.

経費が多くかかる問題があった。However, since the white line and the yellow line of the lane mark made of the above-mentioned paint are formed by applying the paint, the thickness is thin, and they are worn on a short-term day at a frequent intersection at traffic. There was a problem that I had to constantly repaint. For this reason, it is necessary to carry out construction with all traffic closed,
There was a problem that it was expensive.

Then, the synthetic resin emulsion for cement admixture constituting the admixture is in the range of 10 to 5% by weight with respect to the mixed aggregate consisting of natural stone, crushed ceramic color stone, retroreflective glass beads and cement, and 10% by weight. If the content exceeds 5%, the resin tends to become sticky, making it difficult to carry out the connection molding, and if it is less than 5% by weight, it becomes an uncured state, the hardness decreases, and the abrasion resistance,
It has been confirmed that it is inferior in terms of water resistance. Furthermore, the viscosity of the above-mentioned cement admixture may be in the range of 500 to 100 cP at 20 ° C., preferably 200 cP. If it exceeds 500 cP, the viscosity becomes high and molding becomes difficult.

Use a particle size of m. The hue is preferably white or yellow because it is used for the white line and the yellow line of the lane mark. Further, as described above, since the retroreflective glass beads are exposed on the surface of the pavement material as the final product and the bead space is filled with various ceramic aggregates, the effect is particularly great at night and in the rain. In addition to exhibiting retroreflectivity, it is possible to prevent abrasion of the beads, prevent the beads from falling off the surface, and make the surface layer water-permeable.

業が容易であった。According to the paving material of the present invention obtained according to the above-mentioned manufacturing method, a retroreflective glass bead layer having a thickness of 6 to 8 mm is formed on the surface layer, and since the surface layer has water permeability, even if it rains. It was confirmed that the efficiency of retroreflection was good, the retroreflectivity could be maintained for a long period of time, and that stains did not adhere. Also, since only one liquid of the synthetic resin emulsion for cement admixture is mixed as the binder, it does not take time to obtain the mixture, and when it is integrally molded with Northramp mortar, it is integrally molded with Northramp mortar. There was no problem with it, and the manufacturing work was easy.
