Definitions

  • the present invention relates to a bituminous covering structure.
  • Special bituminous coverings are currently extensively used for the industrial and civil waterproofing of prefabricated buildings, foundations, channels, tunnels, hydraulic systems, bridges etc.
  • Said bituminous coverings which are normally produced in sheets and packaged in rolls, are constituted by a reinforcement of glass veil and/or fabric and/or polyester non-woven fabric, impregnated by a mixture of bitumen and/or elastomer resins and calendered to the different thicknesses of use.
  • FR-A-2 464 333 shows a composite covering comprising a bituminous mass and a non-woven polyester reinforcement.
  • the installation of the impermeable covering is performed by slowly unrolling each sheet onto the surface to be treated, simultaneously heating, with a flame, the bituminous layer, which thus firmly adheres to the underlying surface.
  • the sheets overlap one another in their perimetric regions in order to give continuity to the entire covering.
  • a reduction in the mechanical strength has furthermore been observed after exposure to the sun if said reinforcement is made of polyester non-woven fabric.
  • the treated surfaces are normally outdoors, the regions exposed to the sun have, during periods of irradiation, much higher temperatures than the regions in the shade. This occurs because the materials which constitute them are not good thermal conductors.
  • FR-A-1 459 264 discloses a covering accessory comprising a bitumen extract which is reinforced by a metallic grid.
  • FR-A-2 488 630 shows a mixture for paving roads which comprises bitumen and fragmented wire wool.
  • the aim of the present invention is to provide a new bituminous covering which has a structure adapted to eliminate the disadvantages described above in the known art.
  • an important object is to provide a bituminous covering the structure whereof has improved characteristics of mechanical strength, in particular tensile-strength, with respect to current ones.
  • Another important object is to provide a new bituminous covering which has good thermal conductivity, thereby creating uniform temperatures during its use.
  • Not least object is to provide a structure of bituminous covering which can be produced with conventional production systems.
  • the bituminous covering structure according to the invention is constituted by a reinforcement which comprises a mat made of metallic-wool, pressed to the desired thickness.
  • the dimensions of the mat are determined such as to satisfy the requirements of the users, and the thickness can be varied according to the required mechanical properties.
  • Said mat may be reinforced with metallic wires uniformly distributed along mutually orthogonal directions, so as to increase the tensile-strength in both directions.
  • Appropriate materials can be used to size the mat, so as to improve, besides its mechanical characteristics, also its physical-chemical characteristics.
  • the reinforcement of said bituminous covering can comprise a sheet made of a material of metallic origin which co-operates with the mat; the mechanical strength of said sheet depend on the nature of the metal used and are proportional to the diameter of the wires which compose it.
  • bituminous covering according to the invention is completed by a bitumen mixture combined with elastomer resins which, by impregnating the reinforcement and with the consequent calendering to the required thickness, gives the assembly characteristics of impermeableness, adhesiveness and stability, besides ensuring uniformity and compactness.
  • the preferred metallic materials for the execution of the reinforcement of the covering are comprised within a vast range of steels with variable carbon content, from very soft steels to very hard ones, for example C10, C30, C50, C85, and within a vast range of other metals, such as aluminum, lead, copper, zinc and alloys thereof.
  • This uniformity of the temperatures of the various regions eliminates the stresses which occur in current coverings and cause wrinkles, cracks, tears and deteriorations thereof.
  • a not negligible characteristic is that the metallic reinforcement combined with the bituminous mixture gives the structure a sort of thermal buffer between daytime and nighttime.
  • the particular execution of the internal reinforcement allows to obtain coverings with mechanical-physical characteristics comprised within a vast range and therefore suitable for satisfying the most different design and applicative requirements.
  • the metallic materials used for the reinforcement may be any according to the requirements.
  • the dimensions of the bituminous covering, as well as of the materials constituting the bitumen mixture which covers the reinforcement, may be any.

Abstract

La structure décrite est constituée par un revêtement bitumineux du type composé d'une couche de renforcement imprégnée d'un mélange de bitume et de résine élastomère. La couche de renforcement comprend un tapis et/ou un grillage, tous deux en matériaux d'origine métallique. Le tapis peut être constitué d'une feuille de laine métallique pressée jusqu'à présenter l'épaisseur et la densité requises et le tapis peut également être renforcé par des fils métalliques répartis uniformément le long de directions mutuellement perpendiculaires. Le tapis peut également être apprêté avec des matériaux appropriés. Le grillage est fabriqué à partir de fils métalliques et les matériaux utilisés pour le tapis et/ou le grillage sont de préférence l'acier avec une teneur variable en charbon et/ou en aluminium et/ou en plomb et/ou en cuivre et/ou en zinc.
