A mixture of pulverized particles coated with a urethane-based binder and a pretreatment agent, which generates a good reaction substance, is spread in a sheet form under pressure on an adherend such as a road or floor and cured. It forms elastic pavement. Usually, before paving, a primer suitable for the material is applied to the surface of the road or floor. Note that rubber-based elastic substances include natural rubber, synthetic rubber, and other elastic materials. It is a hardening material of various compositions of substances. In addition, elastic pavement is usually constructed at room temperature, but if there is a need to accelerate curing, it can be applied with a heating element of approximately 90'CL'/XF using construction equipment (roller, holding plate, etc.). temperature.
