PROBLEM TO BE SOLVED: To provide a method for manufacturing an artificial road surface that improves global warming.SOLUTION: An artificial water permeable road surface 40 is laid, a high speed water guiding layer 30 is provided in the lower layer of the water permeable road surface 40, the high speed water guiding layer 30 includes gravels or sand, an interfacing layer 20 is provided in the lower layer of the high speed water guiding layer 30, and then a hardened ecological gradation layer 10 is provided further. By the structure, the ecological gradation layer 10 of the lower layer has an effect of supporting and, by providing hollow bodies inside the layer (providing disaster-prevention water-storage hollow bodies, earth-improvement hollow bodies, microorganism-culture hollow bodies or water-keeping hollow bodies as needed), allows rainwater falling on ground surface to quickly penetrate underground, preserves a lot of water, and prompts breeding of microorganisms. When the temperature of the atmosphere is high, underground humidity is evaporated through pipe bodies of the water permeable road surface 40 and environment warming is improved.
