Abstract

PURPOSE: To provide the titled compsn. having excellent processability and practicability and improved high-temperature heat treatment performance, consisting of a bituminous material, a conjugated diene-arom. vinyl hydrocarbon block copolymer and a specified stabilizer.
CONSTITUTION: 95W5wt% conjugated diene such as 1,3-butadiene and 5W95wt% arom. vinyl hydrocarbon such as styrene are block-copolymerized in a hydrocarbon solvent and in the presence of an anionic polymn. initiator to produce a block copolymer (A) having an MW of 5,000W1,000,000. Then 0.001W30pts.wt. stabilizer having at least one N and S atoms in the molecule or mixture of said stabilizer with a radical polymn. inhibitor in a weight ratio of 99/1W10/90, is blended with 100pts.wt. component A. The resulting mixture is blended with 100pts.wt. bituminous material such as straight asphalt in such a proportion that the amount of component A in the above blend becomes 0.5W500pts.wt.
