METHOD FOR REPAIRING ROADBED
PROBLEM TO BE SOLVED: To provide a method for repairing roadbed, which can reliably prevent the occurrence of the swelling, deformation, destruction and the like of the roadbed using a roadbed material containing expansive minerals, while reliably repairing the swelling, deformation, destruction and the like.SOLUTION: In a method for repairing roadbed using a roadbed material containing expansive minerals, the roadbed material is exposed from a surface layer or a base layer of a pavement; a water-soluble acrylic polymer is added to the exposed roadbed material; and after mixing of them, a required amount of the mixture is laid again as the roadbed material.SELECTED DRAWING: None
【課題】膨張性鉱物を含有する路盤材を用いた路盤の隆起、変形、破壊等を確実に補修すると同時に、かかる隆起、変形、破壊等が生じるのを確実に予防することができる路盤の補修方法を提供する。【解決手段】膨張性鉱物を含有する路盤材を用いた路盤の補修方法であって、舗装の表層や基層から路盤材を露出させ、露出させた路盤材に水溶性のアクリル酸系重合体を加えて混合した後、その混合物の所要量を路盤材として再び敷設した。【選択図】なし
