PROBLEM TO BE SOLVED: To provide a modified asphalt composition for adhesion which exhibits a high adhesive force with an adjacent layer during drying and water adhesion and has excellent workability and weather resistance and a mixture therefor, and to provide a laminate thereof.SOLUTION: There is provided a modified asphalt composition for adhesion to at least one adherend selected from the group consisting of a polar resin, metal, an inorganic oxide, asphalt, an asphalt mixture and their composite body which contains 20 mass% or more and 99.5 mass% or less of asphalt (A) and 0.5 mass% or more and 80 mass% or less of a block copolymer (B), where the block copolymer (B) contains at least a conjugated diene monomer unit and a vinyl aromatic monomer unit, the vinyl aromatic monomer unit in the block copolymer (B) is 15 mass% or more and 60 mass% or less, and a peak temperature of a loss tangent (tanδ) by dynamic viscoelasticity measurement of the block copolymer (B) is -50°C or higher and -5°C or lower.SELECTED DRAWING: None |
