Definitions

  • the present invention relates to a method of in situ manufacturing of a road membrane reinforced with continuous wires.
  • the invention relates in particular to the repair of cracked roads and pavements, but also applies to the construction of new pavements.
  • a bituminous mortar composed essentially of sand, a bituminous binder and fines, is interposed between the cracked layer and the wearing course - consisting of a coated material or a coating - about 1 to 3 cm.
  • a prefabricated geotextile is interposed between the cracked layer and the wearing course, possibly with a binder.
  • these materials present many difficulties because it is not obvious to unwind satisfactorily rolls of geotextiles and to lay the sheets whose recovery is difficult to succeed.
  • this system adapts very poorly to the geometry of the roadway and the support; folds are formed in curves and superelevation changes, which affect the effectiveness of the complex.
  • NL-A-7 007 501 describes the use of wire (s) in the installation of road mixes, by gluing the wire through an adhesive bath, or else the application of a sheet which becomes adhesive by melting .
  • the invention relates to a method for in situ manufacturing of a reinforced road membrane, comprising the installation of a binder layer, possibly the interposition of a base or bonding layer and finally the installation of a layer. of rolling in the form of a coating of asphalt or a surface coating, characterized in that one projects by ejection onto the binder layer, a continuous wire or several wires to obtain an entangled assembly forming a tablecloth and constituting the frame.
  • this layer of wires is covered with a layer of aggregate or a prefabricated mesh, possibly with a layer of binder, before the establishment of the following layer or layers.
  • the binder layer is put in place simultaneously with the projection of a continuous wire or set of wires forming a sheet and constituting the reinforcement on this layer.
  • the binder used for the first layer is either a bitumen or a polymer bitumen, which can be fluxed or fluidized, and it can be applied using standard materials either hot or cold in the form of an emulsion, 0.2 to 4 kg / m2, preferably 0.6 to 1.5 kg / m2 of residual binder.
  • the wires projected onto this binder will be included there during the subsequent application of the wearing course (or if necessary of the base or linking layer) and will form the reinforcement thereof. The complex thus obtained will ensure bituminous continuity between the support layer and the new coating.
  • the yarns used according to the invention can be natural or synthetic yarns, treated or not, in particular polyester, polyamide, polypropylene or cellulose derivatives, or else glass. Polyester or polyamide yarns are preferred. They can be used in coils or beams of 1 to 1000 single stranded wires. Their grade can vary in a wide range from 80 to 5000 decitex, preferably from 150 to 400 decitex. According to the invention, 30 to 400 g / m2 of son will be used, preferably 40 to 120 g / m2. The wires projected at high speed onto the binder form with the latter, in the final road complex, a tight reinforced membrane.
  • a clear grid of aggregates This will generally be made of gravel (for example 6/10 mm), spread at a rate of 2 to 10 l / m2, for example about 5 l / m2, but other particle sizes and dosages are possible. These aggregates do not need to be rolled. It is also possible to use a prefabricated lattice, in particular a metallic or polypropylene lattice. In some cases a second layer of binder can be applied.
  • the wearing course is carried out in the usual way, possibly with prior interposition of a base or bonding layer according to current techniques.
  • the invention applies equally well in the case of a hot mix carpet, as in the case of a surface coating.
  • EXAMPLE 1 Repair of a very cracked road due to lack of structure.
  • a bitumen-polymer emulsion (natural latex, such as Neoflex® manufactured by the company SCREG Sud-Est) is used with the spreader at the rate of 1.2 kg / m2 (ie approximately 0.8 kg / m2 of binder residual).
  • Polyester threads (4 threads 167 decitex threads of 30 strands each, supplied by the company Rhône-Poulenc) are sprayed onto the binder layer at a rate of 50 g / m2, using a compressed air ejector gun, so as to get a sheet of tangled threads.
  • the wearing course is carried out by using a traditional mix (0/10 bituminous concrete) at the paver at the rate of 80 kg / m2.
  • EXAMPLE 2 Repair of a crocked road at the exit of the agglomeration.
  • a pavement is obtained comprising a reinforced road membrane (binder + wires) and combining great qualities of solidity and flexibility.
