Abstract
Glass fibers, either in the form of individual filaments or bundles of glass fibers, which have been coated with a chemically-modified asphalt prepared by reacting a bituminous material with an organo metallic compound in the form of an orthoester or an organo metallic boron compound. The coated fibers can be used as reinforcement for bitumen or bitumen plus aggregate to securely tie the glass fiber surfaces to the bitumen.
