Summary:To provide an absorption method of carbon dioxide using porous concrete pavement without including reinforcing bars contained that does not hinder the active use of carbonation/neutralization phenomena.SOLUTION: An absorption method of carbon dioxide in which carbon dioxide is absorbed into porous concrete pavement having at least a multilayer structure composed of a porous concrete layer, a layer having impermeable property, a base course, and a roadbed in order from the surface of the porous concrete pavement, the layer having impermeable property preferably having more air permeability, and the base course being a waste concrete containing calcium hydroxide or calcium silicate hydrate.SELECTED DRAWING: Figure 1 【課題】炭酸化・中性化現象の積極的な利用が障害にならない、鉄筋を含まないポーラスコンクリート舗装を用いた二酸化炭素の吸収方法を提供する。【解決手段】ポーラスコンクリート舗装の表面から順に、ポーラスコンクリート層、不透水性を有する層、路盤、および路床から少なくともなる多層構造を有するポーラスコンクリート舗装に、二酸化炭素を吸収させる、二酸化炭素の吸収方法であり、好ましくは、前記不透水性を有する層が、さらに透気性を有し、かつ前記路盤が、水酸化カルシウムまたはカルシウムシリケート水和物を含むコンクリート廃材である、二酸化炭素の吸収方法である。【選択図】図1
