Definitions

  • the invention relates to a process for preparing a pavement coating material from the material recovered during cold milling of the surface layers of the pavements. It also relates to a machine. implementing said process and using the milled material obtained according to this process.
  • Maintenance of the road surface may, among other things, use so-called cold milling techniques.
  • the surface layers of the coating are removed by milling, with a view to lowering and regularizing the level of the surface, thus preparing it to receive a new coating.
  • the resulting materials can then be either eliminated or reused, if necessary after subsequent storage and reprocessing.
  • Such processing can only be carried out at the cost of additional operations and using ancillary facilities, which increase the total cost of all operations accordingly.
  • an aqueous or organic or aqueous organic liquid composition is used, the nature of said composition depending in fact on the destination of the milled material.
  • an aqueous solution or suspension or simply water can be used as the aqueous composition.
  • an organic composition one can use a solvent or a mixture of organic solvents, for example toluene, heavy or light aliphatic hydrocarbons or other petroleum distillation residues, or a binder or mixture of anhydrous binders, such as lacquers or “cut-back” binders.
  • an aqueous organic composition an aqueous emulsion of bitumen or tar, for example, can be used.
  • the quantity of liquid composition to be incorporated into the milling material is calculated as a function of the various parameters making it possible to define the milling material: this quantity will in particular be a function of the mass of milled material collected, of the particle size curve of said material , the angularity of the grains constituting said material and the compaction energy accepted according to standard SN 670 330 a (PROCTOR test) or similar).
  • the quantity of liquid composition thus calculated will be that which makes it possible to obtain a milled material with an optimal content of compacting liquid.
  • additional mixing can be carried out in order to obtain optimal homogenization of the material mixed with the liquid composition.
  • Such mixing can be carried out on the same milling site, immediately after the incorporation of the liquid composition or during a separate step, in an appropriate installation.
  • the method of the invention can be suitably implemented using a cold milling machine comprising a device for storing the liquid composition, a device for bringing the liquid composition to the milling zone and a device for dose the liquid composition incorporated into the milled material.
  • any known means can be used, such as a tank for example, fixed on the machine itself or on an auxiliary vehicle, the device bringing the liquid composition to the desired level then being arranged accordingly.
  • a metering pump is preferably used, controlled by the speed of advance of the machine. The control of such a pump can be achieved using any suitable known means, for example using an independent tachometer, a tachometer connected to the transmission system of the machine or the milling element of said machine, or through the PTO of the milling element of the machine.
  • the pump flow (Q) is then determined as follows:
  • the milled material resulting from the process according to the invention can be reused immediately or after intermediate storage, in particular for the preparation of foundation layers, adjustment layers or wear layers of roadways.
