Definitions

  • the invention relates to a method for producing a floor covering as well as a floor covering.
  • High traffic lane surfaces such as the various surfaces of Public Reception Areas (ERP), such as stations, as well as industrial floors capable of supporting installations or heavy vehicles, are usually made of asphalt.
  • This asphalt is conventionally formulated from materials having a density between 2.6 and 2.9 g / cm 3 .
  • Such a coating has two major drawbacks. The first is linked to its composition which leads to a surface condition lacking in roughness due to the normal tendency of the largest aggregates to settle and settle.
  • the other disadvantage results from the black color of the asphalt. Indeed, like any black material, such an asphalt has a strong light absorption and thus acts against the efforts made to improve the safety of movement in particular for people with reduced visibility. Furthermore, it must be admitted that a black surface, even a clean one, cannot always be considered aesthetic.
  • Asphalt-based flooring could be replaced by reconstituted soils with hydraulic binder or binder resin, and this either in slabs or cast.
  • soils capable of meeting certain related requirements the particular use to which the soil is to be exposed, the fact remains that the implementation is not always as easy as applying an asphalt, which of course also has a impact on the price of soil construction.
  • asphalt benefits from significant advantages, in particularly its reduced hardening time, its properties acoustic and electric and its ease of maintenance.
  • the invention provides a floor covering that is simple to apply. and having a good resistance value to different agents wear and aggression inherent in heavy loads and the corresponding production method.
  • an asphalt consisting of a mortar and gravel, the mortar comprising a mixture of minus a bitumen and a filler, the mass ratio volume of asphalt mortar to that of gravel being greater than 1.
  • the step of spreading the asphalt is followed a mechanical surface treatment step.
  • the mechanical surface treatment is obtained by sanding.
  • step of spreading the asphalt and the sanding step are separated from each other by a period time that the asphalt cools and hardens.
  • an asphalt having the characteristics stated above has the advantage of obtaining a coating having both surface properties avoiding the risks of slip of users and a waterproofing function of the support.
  • Sanding provides a substantially surface smooth, but not slippery, facilitating both the movement of people or heavy equipment and its maintenance and providing pleasant visual appearance.
  • the ratio of the density of the gravel to that of the mortar charge is chosen so as to find the gravel floating on the mortar.
  • Sanding allows so - in addition to producing a flat surface of the coating - to expose the inside of the gravel according to cut faces which together constitute the plane of the surface of the covering.
  • the gravel then have a pattern through these cutting faces determined by the internal structure of each gravel cut and by the shape of its cutting face, as well as a color other than the usual color of uncut chippings.
  • the mineralogical nature of the gravel determines in which measures the cutting faces are smooth and possibly slippery.
  • the floor covering consists of an asphalt mortar and gravel, the ratio of the density of the mortar asphalt to that of gravel being greater than 1.
  • the floor covering is sanded and its roughness is less than 0.8.
  • the floor covering defined above benefits from a report advantageous quality / price and ease of implementation thanks to its asphalt nature. It is an evolution of asphalt by the choice of its composition and certain technical aspects of its implementation. Incidentally, the flooring of the invention makes it possible to obtain a better aesthetic appearance of the floors by an appropriate choice of the nature of the gravel and their color.
  • the coating of the invention lends itself more particularly to an application on surfaces such as urban and road roads, surfaces of traffic for public transport users at outside and inside a station, ramps, industrial floors, and in general ERP.
  • bitumen can be combined with different additives and constitutes the binder.
  • the asphalt mixture consists of a mortar asphaltic incorporating gravel.
  • a flux is an additive with a high viscosity at a so-called intermediate temperature (around 60 ° C) and a very low viscosity at a so-called high temperature (of the order of 160 ° C).
  • HOSTAMONT or LICOMONT BS 100 marketed by the Clariant Company gives good results.
  • the support on which the asphalt according to the invention must be spread must be perfectly smooth and in particular without holes or bumps.
  • kraft paper can be unrolled on the support.
  • a frame formed by a glass grid can be unwound on surfaces with a slope greater than 3%.
  • you can use solid brass rods. The surface of the modules obtained by this fractionation is variable and depends in particular on the dimensions of the soil to be produced. For some subsequent maintenance work, the layout avoids the patching phenomenon.
  • the asphalt spreading step is followed by an interval approximately 24 hours during which the asphalt cools and hardens.
  • the minimum duration of this interval depends on the place and the season.
  • the surface can then be temporarily left for traffic. We then proceed to a mechanical surface treatment of its surface.
  • This treatment is a sanding. It eliminates at least partially a possible surface layer of bitumen and made appear the gravel, while partially polishing them.
  • the asphalt sanding is advantageously carried out with a sander equipped with a rotary plate on which are mounted diamond plates. Sanding is done with water. Mud resulting from this surface treatment is immediately recovered by a vacuum cleaner to be sent to controlled landfills or to be collected and specially treated.
  • the sanding step is advantageously followed by a cleaning step using a rotary brush with plastic brushes, for example that known under the registered trademark "Nylon".
  • a step of applying an emulsion protection may be provided.
  • the emulsion improves the visual perception of the coating and increases in particular the shine of the ground.
  • such emulsion advantageously implemented in two layers fine, reduces the sensitivity of the soil to fouling and facilitates its interview.
  • the grain size of the gravel as well as the color of the chippings are chosen according to the desired result. So that the choice of the color of the gravel corresponds essentially to aesthetic aspects or surface distinction according to their uses, the choice of grain sizes is made essentially to meet technical requirements. In effect, a mixture of different particle sizes promotes a homogeneous distribution of gravel.
  • MOHS hardness is advantageously between 5 and 7.
  • These gravel have advantageously a size between 2 and 18 mm.
  • the load of gravel is advantageously of the order of 25 to 55% by mass of the asphalt mixture.
  • Figures 1 and 2 respectively show a surface a floor according to the invention and a floor covering according to the invention in a vertical section.
  • Chippings 1 are presented with their cutting faces 2 updates by sanding. Spaces 3 between gravel 1 are filled with a mortar 4. Gravel 5, uncut these, occupy with the gravel 1 the upper part of the flooring. The lower part is occupied by a charge 6.
  • Figure 2 clearly represents the flotation effect at which gravel 1 and 5 are subject because of the density greater load compared to that of gravel. And the Figure 2 also shows layer 7 of the floor covering. This layer 7 is removed by sanding.
  • the invention allows the implementation of the technique of stamping: stamping is applied, immediately after placing the asphalt mixture, while still warm and malleable. We can thus realize decorative, raised patterns that remain apparent after mechanical surface treatment.
  • An emulsion can be applied to the coating after mechanical surface treatment to facilitate its maintenance.
  • the floor covering of the invention lends itself particularly good at resurfacing by sanding giving it back its original appearance and properties.
