ABSTRACT:
A waterproofing UV-resistant bituminous membrane, a system incorporating such a membrane, and a manufacturing process are disclosed. In a particular embodiment, a UV-resistant waterproofing membrane includes a mass of at least one bituminous composition, formed in at least one continuous layer, and of at least one ply of filamentous or fibrous material, embedded in the mass. The membrane is characterized in that the at least present bituminous composition consists of a bituminous mixture based principally on bitumen, SBS elastomeric polymer and mineral fillers and in that said at least one ply (3) consists of a fine web, of open-work structure, with no preferred direction of stress resistance and formed of filaments and/or fibers in a material that is preferably resistant to UV, said web (3) being embedded in the mass (2) of bituminous composition(s) while being situated next to the face (4) designed to be visible or exposed, after laying said membrane (1).
