    摘要: A chemically modified asphalt prepared by reacting an asphalt with a polymerizable vinyl monomer (e.g., styrene) and a rubbery polymer whereby the rubbery polymer is chemically integrated with the asphalt. The chemically modified asphalt can be, if desired, further cross linked by reaction with a cross linking agent such as a polycarboxylic acid, an organic isocyanate or an organic polyepoxide. The chemically modified asphalt compositions of the invention can be used in the treatment of glass fibers as well as in road paving applications and the like.

    摘要: A bitumen composition modified with an organo silane in which a bitumen such as asphalt is reacted with an organo silane containing ethylenic unsaturation or an organo silane containing at least one hydrogen atom bonded to the silicon atoms whereby the organo silanes react with ethylenic unsaturation of the bitumen to chemically bond the organo silane to the bitumen. Also included are bitumens which have been chemically modified by reaction with steam, air, ammonia or aliphatic amines which have been reacted with a silane containing a functional group reactive with the bitumen. Bitumen compositions of the invention are preferably used in the treatment of glass fibers for use as reinforcement in asphalt systems.
