Definitions

  • the subject of the present invention is a process for the in situ production of a composite material obtained by mixing cut fibers and a bituminous grout.
  • the present invention also relates to the device for introducing and cutting fibers adaptable to the machines for manufacturing and spreading bituminous grouts so that these machines can manufacture and spread the composite material.
  • the invention relates essentially to the repair and maintenance of pavements but can also be applied to the construction of new pavements, particularly in an anti-crack recovery complex.
  • Another method consists in applying to the cracked or earthen pavement or to the seat to be protected a geotextile on which a surface course is then produced.
  • This process requires several operations (spreading a layer of binder, applying the geotextile product, spreading another layer of binder).
  • This system is often difficult to apply due to the geometric constraints of the support, which can lead to the formation of folds that are difficult to absorb.
  • the geotextiles used those in which green fibers are incorporated are those which give good results against the rising of cracks.
  • a variant of this process consists in using a green fiber grid in place of the geotextile.
  • Another method consists in spreading fibers, cut or not, on a hydrocarbon binder previously spread over the surface to be treated, this layer is then itself covered by another layer of binder. A layer of aggregates is then spread over this set. This process is delicate to carry out and can lead to overdoses by binding.
  • the present invention consists in incorporating a high dosage of mineral or synthetic fibers cut to a length of between 15 and 100 mm in a bituminous grout.
  • the mixture is in the form of a pasty grout.
  • This mixture is distributed in the application sled by means of screws before being spread on the road.
  • the material acquires its cohesion after the emulsion has ruptured and after the water in the mixture has been discharged.
  • the layer thus applied is rollable within a period of between 15 and 60 minutes.
  • the invention consists in incorporating mineral or synthetic fibers into the slurry in a high proportion.
  • the fibers are cut to a length of between 15 and 100 mm.
  • the invention also relates to a device adaptable to existing machines.
  • This device is characterized in that it comprises means for storing fibers in the form of strand rolls, means for guiding said strands towards cutting devices, cutters and devices for dispersing the fibers in the mixer and / or in the grout distribution screws.
  • mineral fibers and more particularly green fibers will be preferred insofar as they have high mechanical characteristics and have a moderate cost.
  • the length of the cut fibers will be between 15 and 100 mm depending on the effect that one seeks to obtain.
  • the short fibers have the effect of making the bituminous grout more cohesive while the long fibers are more effective against the rising of cracks.
  • the fiber dosage will be between 50 and 300 grams per square meter of surface treated, The high dosages will be used for the treatment of cracked or earthen pavements or when the material is used in an anti-cracking complex.
  • the formulation of the basic bituminous grout will be a type 0 / D formula in which the dimensions of the largest aggregate can be between 6 and 14 mm. Formulas 0/6 will be used when the material is used as an interposing membrane, while formulas incorporating larger aggregates will be used as a wearing course.
  • the machines for manufacturing and applying bituminous grouts are generally mounted on trucks.
  • These aggregates include an aggregate hopper (1). These aggregates are dosed and conveyed to the mixer via a conveyor belt (2) or a transport screw. which regulates the material flow.
  • the emulsion is stored in a tank (3) along with the feed water (not shown in the diagram)
  • the vehicle also includes the storage (4) of various additives (cement, etc.) used in the final composition.
  • the emulsion, water and additives are injected into the mixer through the metering devices (5).
  • the cutting and dispersing devices are known models, their number depends on the dosage of fibers which it is desired to include in the material.
  • the cutting and dispersing devices are driven either hydraulically, mechanically or electrically.
  • the rotational speed of the rotor or cutting rotors is controlled by the rotational speed of the conveyor belt (2) so that the flow rate of the fiber flow produced is proportional to the flow rate of the material.
