Zusammenfassung:To provide a pavement capable of absorbing carbon dioxide and contributing to the reduction of the amount of carbon dioxide in the atmosphere.SOLUTION: A carbon dioxide absorbing pavement structure has a layer having voids and air permeability on the pavement surface side; below the permeable layer is a carbon dioxide absorbing roadbed layer that includes a carbon dioxide absorbing material, which absorbs carbon dioxide at normal temperature and pressure and releases carbon dioxide when heated below 200°C, a stabilizer, aggregate and water, and has properties that allow rainwater to permeate through; and a roadbed is provided below the carbon dioxide absorbing roadbed layer to allow rainwater to infiltrate into the ground through the layer having voids and permeable layer.SELECTED DRAWING: Figure 1 【課題】二酸化炭素を吸収して大気中の二酸化炭素量の削減に寄与することが出来る舗装の提供。【解決手段】本発明の二酸化炭素吸収舗装構造は、舗装表面側には空隙を有し且つ通気性を有する層が設けられ、当該通気性を有する層の下方には、常温常圧で二酸化炭素を吸収し、200℃未満に加熱されると二酸化炭素を放出する二酸化炭素吸収材と安定材と骨材と水を含み、雨水を浸透させることが可能な性質を有する二酸化炭素吸収路盤層が設けられ、二酸化炭素吸収路盤層の下方には路床が設けられており、空隙を有し且つ通気性を有する層により雨水を地中に涵養させることが可能としている。【選択図】図1
