摘要： PROBLEM TO BE SOLVED: To provide a water retentive roadbed structure capable of supplying moisture to the ground surface, when the ground surface becomes a dry state by absorption of water by plants and evaporation of water from the surface without a forced sprinkling device.
SOLUTION: This structure is provided for continuously performing supply of the moisture to the plants and evaporation from a surface layer, by sucking up the moisture in earth to the surface layer by imparting strength of suction by setting a vertically different particle size range. Rainwater can also be stored by using a water retentive material in the earth, and storage water can be utilized by moisture absorption of the plants and the evaporation of the surface layer, by sucking up the water to the surface layer, without still storing the water by taking the structure. As an actual constitution, this water retentive roadbed structure is arranged over the substantially whole surface of a specific area on a roadbed. In the water retentive roadbed structure, the structure is composed of a sucking-up structure having a lower layer 120 substantially formed of a coarse grain size aggregate having relatively weak capillary force, and an upper layer 110 layered in an upper part of the lower layer and substantially formed of a dense grain size aggregate having relatively strong capillary force.
