Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water-retentive pavement stably suppressing a rise in ground temperature for a long period of time. SOLUTION: Characteristically, this heat-insulating and water-retentive pavement comprises: a water-retentive layer 2 which has a water-retentive material 22; a water-retentive-material bearing layer 1 which is provided on the lower section of the layer 2, and which stops the passage of the material 22; and a heat-insulating and water-permeable layer 3 which is provided on the upper part of the water-retentive layer 2, which has water permeability, which stops the passage of the material 22, and which also has heat insulating properties.
