Abstract
A reinforced composite formed of a bitumen, an elastomer or a plastic reinforced with a filler containing a coating thereon in the form of a chemically modified bitumen. The chemically modified bitumen employed is one formed by reaction of a linking agent reactive with the bitumen and containing groups reactive with the filler so that the chemically modified bitumen undergoes a chemical reaction with the filler to thereby intertie the coated filler with the continuous phase.
Claims3
A bituminous composite comprising (1) a bitumen as a continuous phase and (2) a siliceous filler component comprising (a) glass fibers and (b) a coating on the glass fibers, said coating comprising a chemically modified bitumen capable of reaction with the glass fibers to chemically bond the chemically modified bitumen to the glass fibers.
