Abstract
A chemically-modified bitumen composition prepared by reacting a bituminous material with a chromium complex. The composition can be used to coat fillers and glass fibers, either in the form of individual filaments or bundles of glass fibers. The coated fillers and fibers can be used as reinforcement for bitumen or bitumen plus aggregate to securely tie the filler or glass fiber surfaces to the bitumen.
