<p>The filler for a bituminous composition, in particular asphalt matrix, comprises a mixture of a rock-like natural product, for example a rock flour (powdered rock, crushed rock), on the one hand and an industrial product in the form of powdered resin containing cellulosic fibre materials on the other hand. One component of the filler mixture, in a proportion of about 80% by weight, preferably has a particle size of < 0.09 mm. The powdered resin containing cellulosic fibre materials is formed, in particular, on grinding, milling or drilling treatment of clutch and/or brake linings through the flour-like abraded material produced.</p> |
