PROBLEM TO BE SOLVED: To provide a thin-layer pavement structure having toughness and durability that can withstand the traveling of a vehicle loaded with heavy objects and a construction method for the structure. SOLUTION: The surface of a concrete floor 1 coated with a primer composition for impregnation 11 using, as a base, a polysulfide modified epoxy resin which is excellent in flexibility. An epoxy resin mortar composition 12 which is mixed with aggregate, porous with cavities, and highly strong is put on the epoxy resin. The cavities present between the bottom and intermediate part of the resin mortar composition 12 are impregnated with the polysulfide modified epoxy resin by rolling the mortar composition with a mechanical trowel. Consequently, a thin-layer pavement material composition which has both soft and hard properties, toughness, impact resistance and wear resistance, and durability can be provided.
