PROBLEM TO BE SOLVED: To form a floor surface having a wet color and giving a profound impression like a stone pavement just after a rainfall with a simple execution process by containing a solventless transparent resin, a transparent aggregate having a specific total-light transmission factor when mixed with this resin and a colored aggregate at specific wt.%. SOLUTION: This pavement material contains a solventless transparent resin (a), a transparent aggregate (b) having the total-light transmission factor of 70% or above when mixed with the resin (a) and a colored aggregate (c). The transparent aggregate (b) and the colored aggregate (c) of 200-600 pts.wt. in all are added to the resin (a) of 100 pts.wt., and the weight ratio of the colored aggregate (c) against the transparent aggregate (b) is set to 1:0.5-2.5. A sample is filled in a glass cell with the thickness of 5 mm, and the total-light transmission factor is measured in conformity to the measuring method A with an integrating sphere light transmission factor measuring device specified by 5.5 'light transmission factor and total-light reflection factor' in the JIS K7 105 'optical characteristic test method of plastic'. The grain size of the transparent aggregate (b) and the colored aggregate (c) is set to 0.1-5.0 mm.
