In general, various vehicles that ride on roads by applying non-slip pavement of various compositions on the road to prevent the vehicle from slipping due to moisture or ice freezing on sloped roads and roads around schools. Or to ensure the safety of pedestrians.

The conventional method for constructing a non-slip pavement of a road floor includes a pour method of spraying aggregate after the resin is capped on the floor, and a mixed method of mixing resin and aggregate.

However, the method of pouring does not only take a lot of construction time, but also a very complicated work process, and also because of the toxic gas generated when the packaging material itself is ignited. There is a risk of suffocation by the driver due to the generation of toxic gas from the packaging.

In addition, since both the pouring method and the mixing method mix the general aggregate with the resin, the wear of the aggregate is fast, the color is changed quickly, and the bonding strength between the resin and the aggregate is implicated.
