To provide a storage method for an asphalt rubber, which can suppress a decrease in the concentration of rubber powder by suppressing the decomposition of the rubber powder in the asphalt rubber during heating storage.

This storage method for the asphalt rubber, in which the rubber powder is contained in asphalt, is characterized in that the asphalt rubber is heated and stored at 150-175C, suitably, at 165-175C. The storage method can be suitably applied to the asphalt rubber using straight asphalt as the asphalt and using rubber powder, obtained by crushing a waste tire, as the rubber powder.
