Definitions

  • the present invention is concerned with a novel material made of recycled bitumen-derived products such as asphalt shingles.
  • the material comprises, in addition to the recycled shingles, at least one polymer to improve its flexibility and malleability.
  • the material is moulded into a sheet that can be easily bent to follow the surface of supporting material, such as for example a roofing structure.
  • perlite boards are known to have different end uses, for example, as a fire-resistant insulation board to be laid directly on a steel roof deck, followed by a BURTM system.
  • This product has an inorganic perlite content of 70 percent, and accordingly, there is not much hygroscopic cellulose fiber present in such board.
  • extra cellulose fiber and starch binder are necessary and, as a result, the perlite content is necessarily reduced.
  • isoboards be overlaid with a thin layer of a glass fiber board, a wood fiber board or a perlite board.
  • Such overlay can be 1 / -inch "recover board,” a product already in the marketplace as an overlay for existing roofing; or something specifically designed as a blister-protection board to overlay isoboards.
  • Such overlay still blisters when hot-mopped to isoboards.
  • the phenomenon that causes blistering and a test that enables researchers to find suitable products are still unknown. In other words, there is still a great need to develop a blister-free overlay sheet or board.
  • Waste landfills are reaching a crisis level, and as a result, waste management has become even more challenging.
  • Current legislation has rendered the handling and processing of wastes significantly more difficult and costly for industries. As production increases, so does the waste.
  • the need for special departments to handle and dispose of such waste has now become a serious problem affecting space, personnel, transportation and landfill. Unknown to the consumer, these waste disposal costs are ultimately built right into the industry's consumer price.
  • SBS Styrene-butadiene-styrene block
  • a composition in accordance with the present invention is suitable for the manufacture of a sheet of board useful in the building industry, comprising a waste bitumen-containing product, and at least one polymer in an amount sufficient to provide a flexibility and malleability sufficient to allow a workman to bend the membrane upon installation onto the surface of a supporting material or receiving surface.
  • FIGURE 1 shows a perspective view of bonding of the asphalt membrane onto a styrofoam substrate
  • FIGURE 2 shows a perspective view of several sheets of asphalt membrane overlaid on an assembled substrate
  • FIGURE 3 shows a cross section of an asphalt membrane moulded over an edging parapet.
  • the present invention is directed to the recycling of asphalt roof shingles into a novel composition with polymers, that can be cast into sheets or boards suitable for use as a roof overlay or as a waterproofing material in the building industry, including the construction of bridges and podium decks, vertical walls, roofs, and parking garages.
  • Such overlay has excellent physical properties coupled with ease of compounding at low temperatures, i.e., lower than 100°C. This permits simplified moulding of sections of the sheets or boards to the applicable substrate structure, following the application of localized heat.
  • the overlay according to the invention may be produced in various sizes, thickness and lengths depending on the intended use. Perhaps of ordinary skill in the art will easily come to the appropriate combination of these parameters to comply with the required specifications.
  • the overlay comprises a width of up to 4 feet, preferably between 1 and 3 feet; a length varying from 1 to 10 feet, preferably between 2 and 8; and a thickness of at least 1/16 inch.
  • Preferred polymers for increasing the flexibility and permeability comprises ethylene vinyl acetate, polypropylene, polyethylene, polyethylene glycol, chlorosulphonated polyethylene such as HypalonTM, and the like, as well as mixtures thereof.
  • the composition also preferably comprises one or more stabilizers such as thioether or a phenolic derivative like IrganoxTM.
  • a most preferred composition according to the invention would comprise the following:
  • the asphalt membrane or overlay according to the present invention has several important advantages. It has so far shown superior strength to traditional fibre boards.
  • the overlay is a waterproof material which substantially eliminates all blistering, material separation and air pocket problems. Because the overlay comprises asphalt, conventional hot-mop tar bonds directly thereto to form an integral surface. Due to its improved elasticity resulting from the addition of various additives, the overlay can be moulded onto any surface for a variety of uses. For example, laminated directly onto insulation or styroform as in FIGURE 1 , with a shiplapped outer edge to improve joint integrity as in FIGURE 2, or moulded to form ridge caps, gutters, gutter cappings, flashings, starter sheets, etc.
  • Figure 3 shows an asphalt sheet moulded over a roof edge parapet.
  • composition of shingles may vary greatly from one source to the other.
  • the present invention has been developed to allow the use of any and all waste shingles produced currently.
  • Typical compositions of shingles include bitumen with 100-dmm penetration asphalt flux; a linear SBS block copolymer comprising a styrene-butadiene ratio of 31 to 69; the remaining being calcium carbonate as a filler.
  • FIGURE 2 depicts an assembly 22 of several individual laminated sections 20 of the asphalt membrane 10 and the styrofoam underlay 12 as described above and shown in FIGURE 1.
  • sections of styrofoam underlay 12 can be laterally fastened together using the polyurethane adhesive blend 14 to bond their vertical edge faces 24 together.
  • the sheets of asphalt membrane 10 can be overlaid and bonded to the underlying styrofoam surface 12 using the polyurethane adhesive blend 14.
  • Flush abutting joints 26 between the overlying asphalt membranes 10 are ensured by overlapping the top edges 28 of the underlying styrofoam surface sections 12 with the lateral edges 30 of the asphalt membrane 10. This ensures flush abutting joints 26 of the asphalt membrane 10, creating a large waterproof asphalt membrane surface 36.
  • a flashing 32 which can equally be a thin strip of asphalt membrane moulded to fit, can be used to join the asphalt surface 36 to a roof edging parapet 34. This allows for easy bonding of the flashing 32 to the flat roofing asphalt membrane surface 36.
  • FIGURE 3 in which a cross section of a roof surface 33, overlaid with a laminated section 20 of a styrofoam surface 12 and asphalt membrane overlay 10, and an edging parapet 34 is shown.

Abstract

L'invention concerne un matériau constitué de produits dérivés de bitume recyclé tels que des bardeaux d'asphalte. Le matériau comprend, en complément des bardeaux recyclés, au moins un polymère destiné à améliorer sa flexibilité et sa malléabilité. Le matériau est moulé sous forme de feuille (38) qui peut être facilement courbée de façon à épouser la surface d'un support, par exemple une structure de toit (33,34).
