Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the durability of a top coat and the safety during use, by applying a specified two-component urethane paving material with two or more spraying works to facilitate the execution and obtain an even finish face. SOLUTION: A two-component urethane paving material containing a prepolymer having isocyanate groups at the end, a compound including polyol compounds, and granular rubber chips of 10-40wt.% against these total weight is applied at least once with spray coating and cured. As a final stage, a two- component urethane paving material containing prepolymer having isocyanate groups at the end, a compound including polyol compounds, and granular rubber chips of 25-40wt.% against these total weight is sprayed on the paving face and cured. In this way, the executive work is facilitated and an even surface can be obtained. And also, the durability of the top coating layer and the safety during use can be improved.
