ROADBED MATERIAL
To provide a roadbed material with added stabilizer, having a sufficient strength even if rainwater permeates through a roadbed, preventing runoff of a carbon dioxide absorber, maintaining carbon dioxide absorption capacity as well, capable of recharging rainwater underground, and furthermore having a characteristic that the carbon dioxide adsorption capacity is restored by releasing an absorbed carbon dioxide when heated to less than 200°C after adsorption of the carbon dioxide.SOLUTION: A roadbed material of the present invention contains an asphalt-based stabilizer (foamed asphalt or asphalt emulsion), and a carbon dioxide absorber (CO2 absorber) that absorbs a carbon dioxide (CO2) at normal temperature and pressure, and releases a carbon dioxide (CO2) when heated to less than 200°C. The CO2 absorber is preferably any of sodium ferrite or potassium carbonate.SELECTED DRAWING: Figure 1
【課題】安定材を添加した路盤材であって、雨水が路盤に浸透しても十分な強度を有し、二酸化炭素吸収材の流出を防止し、二酸化炭素吸収能力を維持するとともに、雨水を地下に涵養することができ、更に、二酸化炭素を吸収しても２００℃未満に加熱することで、吸収した二酸化炭素を放出し、二酸化炭素吸収能力が回復する性質を有する路盤材の提供。【解決手段】本発明の路盤材は、アスファルト系安定材（フォームドアスファルト或いはアスファルト乳剤）と、常温常圧で二酸化炭素（ＣＯ２）を吸収し、２００℃未満に加熱されると二酸化炭素（ＣＯ２）を放出する二酸化炭素吸収材（ＣＯ２吸収材）を包含する。前記ＣＯ２吸収材は、ナトリウムフェライト、炭酸カリウムの何れかであるのが好ましい。【選択図】図１
