Abstract

The invention relates to a method for optimising the roughness of a traffic area. It is characterised in that, in order to constitute 8 the antiskid material, at least one powdery substrate 13, which has an essentially continuous size grading over a wide predetermined range is thoroughly mixed 12 with at least one binder 14, capable of maintaining a relatively considerable flexibility, after installation of the material.

Description

L'invention se rapporte a un procede en vue d'optimiser la rugosite d'une aire de circulation ainsi qu'aux moyens en vue de la mise en oeuvre du procéde et aux aires de circulation ainsi traitees. The invention relates to a method for optimizing the roughness of a circulation area as well as to the means for implementing the method and to the circulation areas thus treated.

Notamment mais non exclusivement, l'invention intéresse l'aménagement de zones de freinage à forte rugosite sur des voies de circulation d'automobile. In particular but not exclusively, the invention relates to the development of braking zones with high roughness on automobile traffic lanes.

Dans le domaine de l'aménagement de zones antidérapantes sur des surfaces susceptibles d'être glissantes, il est connu (FR-A-2.198.029) d'appliquer sur la dite surface une couche de matériau adhesif puis de mettre en forme cette couche selon un motif tridimensionnel et enfin de la saupoudrer de particules de matiere dure. In the field of fitting non-slip areas on surfaces liable to be slippery, it is known (FR-A-2.198.029) to apply a layer of adhesive material to said surface and then to shape this layer in a three-dimensional pattern and finally sprinkle it with hard matter particles.

Ce type de traitement de surface convient bien aux sols des salles de sport et/ou aux pistes de course. This type of surface treatment is well suited to the floors of sports halls and / or race tracks.

Malheureusement, les surfaces ainsi traitées ne peuvent supporter sans s'user prématurément les passages répetes de véhicules automobiles, notamment lorsque ceux-ci effectuent des décélérations importantes sur ces surfaces. Unfortunately, the surfaces thus treated cannot withstand premature passage of motor vehicles without prematurely wearing out, in particular when the latter make significant decelerations on these surfaces.

Dans le domaine du traitement anti-dérapant de passages pour pietons soumis également au passage intensif de vehicules automobiles, il est connu (FR-A-2.327.365) de recouvrir au moins partiellement la dite zone de passage d'un revêtement an matiere plastique tel une plaque souple pourvue de nervures. In the field of the non-slip treatment of passages for pedestrians also subject to the intensive passage of motor vehicles, it is known (FR-A-2,327,365) to cover at least partially the said passage zone with a plastic coating. like a flexible plate provided with ribs.

S'il convient pour assurer la sécurité des piétons, ce type de revêtement ne peut cependant pas être utilisé pour constituer des zones en vue de permettre la décélération optimale de véhicules automobiles. While it is suitable for ensuring pedestrian safety, this type of coating cannot, however, be used to constitute zones in order to allow optimal deceleration of motor vehicles.

Un resultat que l'invention vise à obtenir est un procéde en vue d'optimiser la rugosité d'une aire de circulation, qui ne présente pas les inconvenients des techniques précitees.  One result that the invention aims to obtain is a method for optimizing the roughness of a traffic area, which does not have the drawbacks of the aforementioned techniques.

A cet effet, l'invention a pour objet un tel procedé notamment caractérisé en ce que
- d'une part, pour constituer le matériau anti-dérapant, on mélange intimement au moins un substrat pulvérulent qui présente une granulométrie sensiblement continue sur un large intervalle donne avec au moins un liant apte a conserver une souplesse relativement importante après pose du matériau et,
- d'autre part, pour mettre en oeuvre ce matériau
sur l'aire a traiter, on dépose une couche de matériau d'épaisseur sensiblement uniforme puis,
on recouvre cette couche d'un élément protecteur de manière à l'isoler au moins temporairement de l'air ambiant,
on attend le début de la solidification du liant puis on réalise la mise en forme de la -surface.To this end, the subject of the invention is such a method notably characterized in that
on the one hand, to constitute the non-slip material, intimately mixing at least one powdery substrate which has a substantially continuous particle size distribution over a wide interval gives with at least one binder capable of retaining a relatively high flexibility after laying the material and ,
- on the other hand, to use this material
on the area to be treated, a layer of material of substantially uniform thickness is deposited, then,
this layer is covered with a protective element so as to at least temporarily isolate it from the ambient air,
we wait for the start of solidification of the binder and then we carry out the shaping of the -surface.

L'invention a également pour objet les moyens en vue de la mise en oeuvre de ce procéde, lesquels moyens sont notamment caractérisés en ce qu'ils comprennent
- au moins un substrat pulvérulent presentant une granulométrie sensiblement continue sur un large intervalle donné,
- au moins un liant qui, après pose du matériau, conserve une souplesse relativement importante,
- au moins un élément protecteur permettant de réaliser
une relative isolation du matériau posé par rapport à l'air
ambiant.The subject of the invention is also the means for implementing this process, which means are in particular characterized in that they comprise
- at least one pulverulent substrate having a substantially continuous particle size over a wide given interval,
- at least one binder which, after laying the material, retains a relatively high flexibility,
- at least one protective element making it possible to produce
relative insulation of the laid material from air
ambient.

Ces moyens sont également caractérisés en ce qu'ils comprennent :
- au moins un moyen en vue d'assurer une
anti-sédimentation du substrat melange au liant, et/ou
- au moins un moyen en vue de déterminer le debut de
solidification du liant.These means are also characterized in that they include:
- at least one means to ensure
anti-sedimentation of the substrate mixed with the binder, and / or
- at least one way to determine the start of
solidification of the binder.

L'invention sera mieux comprise à l'aide de la description ci-après faite, à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente schématiquement :
- figure 1 : un synoptique du procédé,
- figure 2 : vue en coupe, une surface traitee selon le
procéde de l'invention.The invention will be better understood with the aid of the description below, given by way of nonlimiting example, with reference to the attached drawing which schematically represents:
- Figure 1: a block diagram of the process,
- Figure 2: sectional view, a surface treated according to the
procedure of the invention.

En se reportant au dessin, on voit que, pour optimiser la rugosite d'une aire de circulation 1, au moyen d'un matériau 2 comprenant des particules 3 de matière dure et un liant 4 en vue de realiser l'ancrage de ces particules 3 sur l'aire traitée 1 :
- on prépare 5 l'aire à traiter en effectuant un nettoyage et si besoin un sechage 6 de la surface apparente de l'aire puis, - - on etend 8 le matériau anti-dérapant 2,
- on pose 9 le matériau anti-derapant 2,
- on réalise 10 une mise en forme de la surface apparente de la couche 11 constituée, de manière à en renforcer le caractere anti-derapant. Referring to the drawing, it can be seen that, to optimize the roughness of a circulation area 1, by means of a material 2 comprising particles 3 of hard material and a binder 4 with a view to anchoring these particles 3 on the treated area 1:
- the area to be treated is prepared 5 by carrying out cleaning and if necessary drying 6 of the apparent surface of the area then, - - the anti-slip material 2 is spread 8,
- the anti-slip material 2 is placed 9,
- Shaping is carried out of the apparent surface of the layer 11 formed, so as to reinforce its anti-slip character.

Cependant, selon l'invention :
- d'une part, pour constituer 8 le matériau anti-derapant, on mélange 12 intimement au moins un substrat pulvérulent 13 qui présente une granulométrie sensiblement continue sur un large intervalle donné avec au moins un liant 14 apte a conserver une souplesse relativement importante après pose du matériau et,
- d'autre part, pour mettre en oeuvre ce matériau :
sur l'aire a traiter, on etend 9 une couche ll de matériau d'epaisseur sensiblement uniforme puis,
on recouvre 15 cette couche 11 d'un élément protecteur 16,
on attend 17 le debut de la solidification du liant et on realise 10 la mise en forme de la surface.However, according to the invention:
- On the one hand, to constitute 8 the anti-slip material, intimately mixing 12 at least one pulverulent substrate 13 which has a substantially continuous particle size over a wide given interval with at least one binder 14 capable of retaining a relatively large flexibility after laying material and,
- on the other hand, to use this material:
on the area to be treated, a layer ll of material of substantially uniform thickness is extended 9 then,
this layer 11 is covered 15 with a protective element 16,
the start of solidification of the binder is waited for 17 and the surface is formed 10.

Dans une variante de réalisation, lors de la préparation de l'aire à traiter, on pose une sous-couche d'accrochage. In an alternative embodiment, during the preparation of the area to be treated, a bonding undercoat is applied.

Dans une autre variante, la couche est réalisée entierement en usine puis simplement collee sur l'aire à traiter. In another variant, the layer is produced entirely in the factory and then simply bonded to the area to be treated.

L'attente 17 permet de realiser la mise en forme sans risque de coulage du matériau anti-dérapant 2. The wait 17 allows the shaping to be carried out without risk of the non-slip material 2 pouring.

Suivant l'invention, lorsqu'on constitue 8 le matériau anti-dérapant 2, on incorpore 18 au mélange de liant 14 et de substrat pulvérulent 13 un agent 19 permettant d'assurer une anti-sedimentation du substrat. According to the invention, when constituting 8 the non-slip material 2, 18 is incorporated into the mixture of binder 14 and of powdery substrate 13 an agent 19 making it possible to ensure anti-sedimentation of the substrate.

Les moyens en vue de la mise en oeuvre du procédé de l'invention comprennent principalement
- au moins un substrat pulvérulent 13 presentant une granulométrie sensiblement continue sur un large intervalle donné,
- au moins un liant 14 qui, après pose du matériau, conserve une souplesse relativement importante,
- au moins un élément protecteur 16 permettant de realiser une relative isolation du matériau 2 posé.The means for implementing the method of the invention mainly comprise
at least one pulverulent substrate 13 having a substantially continuous particle size over a large given interval,
at least one binder 14 which, after laying the material, retains a relatively high flexibility,
- At least one protective element 16 making it possible to achieve relative insulation of the material 2 laid.

Ils comprennent également
- au moins un moyen 19 en vue d'assurer une anti-sédimentation du substrat 13 mélangé au liant, et/ou
- au moins un moyen en vue de determiner le début de solidification du liant 14.They also include
at least one means 19 for ensuring anti-sedimentation of the substrate 13 mixed with the binder, and / or
- at least one means for determining the start of solidification of the binder 14.

Conformément à l'invention, le substrat pulvérulent 13 a une granulométrie croissante échelonnée par paliers relativement etroits sur un tres large intervalle préétabli de granu-lometrie.  In accordance with the invention, the pulverulent substrate 13 has an increasing granulometry staggered in relatively narrow steps over a very wide predetermined interval of granulometry.

Dans un mode préfére de réalisation, le substrat pulvérulent 13 a une granulométrie qui s'etend sur un intervalle compris entre quarante et trois cent cinquante microns. In a preferred embodiment, the pulverulent substrate 13 has a particle size which extends over an interval of between forty and three hundred and fifty microns.

Avantageusement, le substrat comprend en pourcentage avec une tolérance de plus ou moins deux points environ
6,5 X de particules de quarante à cinquante microns, 73 X de particules de cinquante à deux cent cinquante microns, 20,5 X de particules de deux cent cinquante à trois- cents microns.Advantageously, the substrate comprises in percentage with a tolerance of more or less about two points
6.5 X of particles of forty to fifty microns, 73 X of particles of fifty to two hundred and fifty microns, 20.5 X of particles of two hundred and fifty to three hundred microns.

Selon l'invention, les particules 3 constituant le substrat 13 sont principalement constituées de silice. According to the invention, the particles 3 constituting the substrate 13 mainly consist of silica.

Avantageusement, le liant est choisi très souple pour conferer au matériau anti-dérapant une résistance å la compression inférieure à quinze et de preference de l'ordre de six newtons par millimetre carré seulement. Advantageously, the binder is chosen to be very flexible to confer on the non-slip material a compressive strength of less than fifteen and preferably of the order of six newtons per square millimeter only.

La souplesse du liant est extremement importante pour la tenue et sa résistance à l'arrachement et à la fissuration. The flexibility of the binder is extremely important for the strength and its resistance to tearing and cracking.

Suivant l'invention, le liant 14 est un méthacrylate qui presente l'avantage d'une polymérisation rapide c'est å dire environ vingt cinq minutes. According to the invention, the binder 14 is a methacrylate which has the advantage of rapid polymerization, that is to say approximately twenty five minutes.

Contrairement aux produits les plus proches connus qui comprennent un substrat pulvérulent de granulometrie fixe et un liant dur (de trente huit à soixante newtons par millimètre carre de résistance à la compression), le matériau objet de l'invention se caractérise donc par une granulometrie sensiblement continue et un liant tres souple. Unlike the closest known products which comprise a powdery substrate with a fixed particle size and a hard binder (from thirty eight to sixty newtons per square millimeter of compressive strength), the material object of the invention is therefore characterized by a substantially particle size continuous and a very flexible binder.

De maniere classique, le matériau anti-dérapant contient principalement environ 78 % de substrat et 20,5 % de liant. Conventionally, the non-slip material mainly contains about 78% of substrate and 20.5% of binder.

Le matériau contient également environ 0,6 % d'un agent catalyseur de préférence, à reaction virulente, tel un péroxyde.  The material also contains approximately 0.6% of a catalyst agent, preferably with a virulent reaction, such as a peroxide.

Bien entendu, cet agent catalyseur n'est mélange au matériau qu'au moment de son utilisation. Of course, this catalyst agent is not mixed with the material until it is used.

Cette opération est classique et n'apparaft pas sur le schema synoptique.  This operation is classic and does not appear on the block diagram.

Outre cet agent catalyseur, l'agent d'anti-sédimentation 19 incorpore au matériau intervient dans le matériau pour environ 0,48 X.  In addition to this catalyst agent, the anti-sedimentation agent 19 incorporates into the material intervenes in the material for approximately 0.48 X.

Dans une forme préférée de mise en oeuvre, l'élément protecteur 16 permettant de réaliser une relative isolation du matériau 2 posé, est principalement constitue de sable de granulométrie de deux cent cinquante microns. In a preferred form of implementation, the protective element 16 making it possible to achieve relative insulation of the material 2 laid, is mainly constituted by sand with a particle size of two hundred and fifty microns.

Cet élement protecteur 16 a pour fonction annexe d'abriter de l'oxygène de l'air, le matériau anti-derapant pose et ainsi d'inhiber un certain temps le catalyseur du liant pour permettre l'impression et toutè la surface du matériau anti-dérapant posé lorsque de grandes surfaces sont traitées. This protective element 16 has the additional function of sheltering oxygen from the air, the anti-slip material poses and thus inhibiting the catalyst of the binder for a certain time to allow printing and all over the surface of the anti-slip material. - slip applied when large areas are treated.

Outre son action retardatrice, l'élément protecteur 16 a un rôle principal, d'une part1 lors de l'opération d'impression et, d'autre part, lors du début de l'usage d'une bande neuve. In addition to its delaying action, the protective element 16 has a main role, on the one hand during the printing operation and, on the other hand, when the use of a new strip begins.

En effet, même si l'opération d'impression n'est realisée dans la pratique que trois ou quatre minutes apres le début de la polymérisation du liant, il permet d'éviter l'adhérence du moyen d'impression sur le matériau posé. Indeed, even if the printing operation is only carried out in practice three or four minutes after the start of the polymerization of the binder, it makes it possible to avoid the adhesion of the printing means to the material laid.

Par ailleurs, sur une bande neuve, le substrat pulvérulent est enrobe de liant et l'élément protecteur vient creer par dessus une première micro-rugosite. Furthermore, on a new strip, the powdery substrate is coated with binder and the protective element creates over a first micro-roughness.

L'épaisseur de la couche déposée a bien entendu une épaisseur déterminée pour satisfaire aux tolérances routieres. The thickness of the deposited layer has of course a thickness determined to meet road tolerances.

De préférence, cette épaisseur avoisine vingt cinq dixième de millimetres.  Preferably, this thickness is around twenty five tenths of a millimeter.

Quant à l'utilisation de ce matériau, il permettra de créer en amont d'une zone dangereuse une zone de revêtement ayant d'une part, une consistance particuliere pour être décelable à l'oreille par le conducteur du véhicule franchissant la dite zone de revetement et d'autre part, une texture offrant des qualités optimales de rugosité donc d'adhérence pour un véhicule susceptible de décélérer fortement. As for the use of this material, it will create upstream of a dangerous zone a coating zone having on the one hand, a particular consistency to be detectable by ear by the driver of the vehicle crossing said zone of coating and on the other hand, a texture offering optimal qualities of roughness therefore grip for a vehicle likely to decelerate strongly.

Ce matériau a l'avantage de pouvoir être coloré dans la masse de même que de pouvoir comporter des micro-billes de verre lui conferant un grand pouvoir réfléchissant.  This material has the advantage of being able to be colored in the mass as well as of being able to include glass microbeads giving it a great reflecting power.

Les macro-rugosités obtenues par sa mise en forme et les micrG-rugosités obtenues par sa composition confèrent au produit, en plus d'une grande adhérence, une grande résistance à l'usure et donc une longevite certaine. The macro-roughness obtained by its shaping and the micrG-roughness obtained by its composition give the product, in addition to great adhesion, great resistance to wear and therefore a certain longevity.

En outre, se présentant sous la forme d'un mortier et non d'un support revêtu superficiellement de charges, il se régénère automatiquement.  In addition, being in the form of a mortar and not of a surface-coated support, it regenerates automatically.
