Definitions

  • the invention relates to a method of implementing a bituminous waterproofing sheet intended to receive a layer of poured asphalt, with the aim of sealing in particular of flat roofs, civil engineering structures, floors. parking lots, retention basins, etc.
  • FR-A-2 580 990 Another proposed solution (FR-A-2 580 990) consists in incorporating into the bituminous sheet a woven or non-woven screen impermeable or almost impervious to the underlying bitumen. In practice, it is then necessary to choose, for the bituminous composition of the sheet, a bitumen of higher density and softening point than the bitumens normally used and to use a screen of heavy grammage (50 to 500 g / m2). Tests show that this is not enough to prevent bitumen rising through the asphalt layer subsequently deposited, and the product is expensive.
  • a fabric of thermoplastic thread melting at a temperature below about 200 ° C. is added to a bituminous sheet and is intended to come into direct contact with the surface to be protected.
  • the invention makes it possible to solve the problem by providing a method of implementing a bituminous waterproofing sheet intended to receive a layer of poured asphalt and consisting of a reinforcement impregnated with a bitumen modified with fillers and polymers. and comprising a fusible layer of material, characterized in that a meltable material is used for the fusible layer at a temperature below the pouring temperature of the particular asphalt used, the bituminous sheet is put in place so that said fusible layer constitutes the face on which the layer is poured of asphalt and sufficient melt heat is absorbed by said fusible layer so that the melting of the underlying bitumen is thereby prevented.
  • the term “fusible layer” means a layer whose latent heat characteristics of change of state associated with physical characteristics (grammages, thicknesses, etc.) allow the total or almost total fusion of the layer, with absorption of heat. It is this absorption of heat which will prevent the bituminous sheet from going up in temperature too much and the bitumen from liquefying.
  • the asphalt is poured at temperatures of the order of 200 to 240 ° C, depending on the exact composition of the asphalt used but is in any case less than 260 ° C which is the maximum temperature of the usual tests. In the screens used in the prior art, either the material used, and this is particularly the case with glass veils, has a melting point significantly higher than the pouring temperature of the asphalt, or the grammage of point product. equivalent melting used (50 to 500 g / m2) allows at most only a partial softening of the material which continues to transmit heat to the lower layer.
  • the fusible material used must have a sufficient latent heat of change of state and be compatible with the bituminous sheet and the asphalt, and a plastic material in the form of a nonwoven with a grammage of 20 to 60 g / m2 will advantageously be used. , preferably from 20 to 40 g / m2. Good results are obtained with polyesters, which in particular give very good adhesion between the bituminous sheet and the asphalt subsequently poured. It will also be noted that polyethylenes in general are not suitable since their latent heat of change of state is not sufficient. The specialist will determine by appropriate tests whether the latent heat of a given product is sufficient for use in a given context, depending on the particular bitumen and asphalt.
  • a bituminous sheet 1 is prepared by impregnating a reinforcement 2, for example a 100 g / m2 glass veil, using a bituminous composition 3, optionally a bitumen composition modified by polymers (SBS, APP or polypropylene commonly used in the field, for example one of those available on the market. It is not necessary to modify the properties of the commercial compositions, with the advantages which flow therefrom.
  • the reinforcement 2 will be located in the lower part of the finished bituminous sheet and has the role of giving the sheet a certain strength during handling and implementation.
  • the bituminous sheet After impregnation of the reinforcement, the bituminous sheet is calendered and receives a layer 4 of a fusible material in the temperature range of asphalt casting.
  • the nature and the quantity of this meltable material are determined so that it undergoes a total or almost total melting during the pouring of hot asphalt. This fusion taking place with absorption of heat due to the change of state of the material, part of the heat given off by the asphalt is thus absorbed without raising the temperature and the underlying bitumen is not brought to a sufficient temperature. so that it can go up through the layer of asphalt that we just deposited.
  • a nonwoven of fusible material weighing 20 to 60 g / m2, preferably 20 to 40 g / m2, will be used for this purpose. The nonwoven form is used for practical industrial manufacturing reasons but other techniques of applying suitable material could be used. Polyester is a perfectly suitable material, giving in addition to excellent adhesion between the bituminous sheet and the asphalt layer.
  • the thickness of the strip is reduced on the two edges of the strip, on one side on the face upper (6) and on the other side on the lower face (7) so that overlapping two adjacent strips, it does not form excess thickness ( Figure 2).
  • This reduction in thickness can be done during calendering or by removing material from the calendered sheet.
  • FIG. 3 schematically represents the use of the bituminous sheet according to the invention, this sheet 1 being placed with or without fixing on the support 8 to be coated, for example a concrete floor, then a layer of asphalt 9 is poured onto sheet 1.
  • the underside 5 of the sheet 1 comprises a waterproof sheet, a dispersion of mineral particles (obtained by sanding or sanding for example), etc., in order to allow a pose with independence, semi-independence or total adhesion.
  • the main advantages of the process according to the invention is that it makes it possible to obtain all the conventional advantages of two-layer sealing systems. consisting of a bituminous screed or a bituminous sheet covered with a layer of asphalt.
