| description | PROBLEM TO BE SOLVED: To provide an elastic pavement material solving the problem that the durability of a surface layer for stress is low, the finish of the surface layer is difficult to be held constant, workability of a mixture for forming the surface layer is low, and the working life of the mixture is short. SOLUTION: In the polyurethane elastic pavement material comprising a polyurethane elastic pavement layer (A), a polyurethane primer layer (B) and the surface layer (C), the surface layer (C) comprises water-contained magnesium silicate (C-1) as a main component, and the crystal of a layered state whose cross section area is rectangular contains inorganic fiber having a cross section structure arranged on the orthogonal line of the crystal cross section and polyurethane resin (C-2). (C-1)/(C-2) (weight ratio) of the surface layer (C) is preferably 5-20/100, and the hardness of the surface layer (C) is preferably 70-90. |
