Definitions

  • the present invention relates particularly to emergency stop lanes, which are provided, for example, on the lateral edges of multi-lane roads or motorways and more generally to the road lanes usually not subject to vehicle traffic. .
  • the invention relates to pavement strips of this type, which are produced in a draining coating, such as a draining asphalt.
  • a draining mix is an aggregate-bitumen mixture that has a void percentage generally greater than 20%. Draining asphalts are experiencing a strong development as a wearing course on high traffic roads, in particular on motorways, urban bypasses, complementary development links of the motorway network.
  • the emergency stop strip is also coated in the same way.
  • Document FR-2.615.520 relates to a bituminous composition for cold-cast mixes. This document discusses the use of cold-cast mixes for the maintenance of worn pavements of all kinds. The document also indicates that the phase bituminous makes it possible to bind the aggregates to the support and to ensure the tightness of the whole.
  • the subject of the present invention is therefore an emergency stop strip or other strip of roadway usually not subject to traffic, comprising a main coating draining in asphalt draining or porous concrete. Said coating is covered by a layer secondary in a material impervious to residues of a reconstituted particle size, intended to protect said strip against clogging of its main coating by the residues which deposit therein according to the characteristics of claim 1.
  • the aggregates can be of reconstituted particle size of size 0/4, 0/5 or 0/6.
  • a bitumen emulsion can be produced from a bitumen of grade greater than or equal to 40/50, the bitumen content of which is greater than 55%.
  • the thickness of this secondary layer can vary between 0.4 and 1.5 cm approximately.
  • the setting regulating additives may include thickeners, shear thinners or viscosants, or any other similar product.
  • the setting regulator additives may also include an accelerator.
  • the secondary layer is advantageously applied with a density of 12 to 20 kg / m 2 .
  • the height between the upper surface of the secondary layer and the upper surface of the coating of the circulating part is preferably less than 1 cm.
  • the surface of the secondary layer can be at the same level on the surface of the coating of the circulated part of the roadway.
  • Another subject of the invention is the use of a cold bituminous grout to produce, on an emergency stop strip or any other strip not usually subjected to the circulation of a roadway, a layer protection against clogging by residues deposited there.
  • the basic road surfacing used according to the invention is produced conventionally in a draining mix or porous concrete.
  • the composition of such a draining mix or porous concrete is perfectly known to those skilled in the art. It is the same for the means to be used for the production of pavements from these materials.
  • the emergency stop strip made from such a draining coating is coated with a secondary layer of poured bituminous concrete.
  • This poured bituminous concrete is a cold bituminous grout.
  • a cold bituminous grout is used.
  • Such a cold bituminous grout is a homogeneous mixture of fillerized sand, gravel, emulsion, water and setting regulating additives.
  • the dosage chosen depends on the caliber selected and the traffic.
  • the aggregates are successively introduced first, then the supply water and finally the emulsion.
  • the mineral additions are made in the aggregates and the liquid additions in the feed water.
  • the dosage of the emulsion varies between 12 and 14% by dry weight of aggregates
  • the wetting water varies between 8 and 15% by dry weight of aggregates
  • the setting accelerator varies from 0 , 1 to 1.5% by dry weight of aggregates
  • the thickener between 0.1 and 1.5% by weight of emulsion.
  • This thickener is essentially in liquid form. It is intended to freeze the grout but does not thicken the emulsion. It is added either in the filler water or in the emulsion. It is also advantageous to use rheofluidifiers or viscosants to replace it.
  • the emulsion can be of several types. It can be a bitumen emulsion produced from an 80/100 bitumen with a content greater than 60%. It can also be an emulsion elastomer obtained by incorporating a latex into the aqueous phase of the emulsion.
  • the accelerator can be in solid form (cement, slaked lime, quicklime) or in liquid form.
  • the reconstituted aggregates are preferably of size 0/4, 0/5 or 0/6.
  • the particle size components will be between 95% and 100% at 4 mm, 35% at 40% at 2 mm and 6% at 9% for 0.08 mm.
  • the grout is implemented by means of a specific compact machine which includes the aggregate hoppers, the emulsion tank, the water tanks and various additives, a continuous mixer and the applicator sled.
