ABSTRACT:
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 atom 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.
