<p>PCT No. PCT/CH79/00146 Sec. 371 Date Aug. 6, 1980 Sec. 102(e) Date Jul. 21, 1980 PCT Filed Nov. 21, 1979 PCT Pub. No. WO80/01179 PCT Pub. Date Jun. 12, 1980.A process for producing bituminous surfacing, bituminous surfacing produced by the process and hot plant mix for carrying out the process. To improve the resistance to fracture, the proposed bituminous surfacing contains metal fibers, for example steel fibers of finite length. These fibers can be admixed to the mix of solids mix and bituminous binder in the course of the preparation of the hot plant mix or in the course of laying the hot plant mix. Due to the compaction of the hot plant mix to form the bituminous surfacing, the metal fibres are bent and thus loop around the particles of the solids mix and/or form a network with one another to give a kind of random nonwoven fabric.</p> |
