Description

La présente invention concerne des bordurettes, un procédé de fabrication et un dispositif de réalisation de telles bordurettes.The present invention relates to edging, a manufacturing method and a device for producing such edging.

On appelle ici bordurettes, les bordures utilisées sur les voies de circulation de véhicules, notamment sur les voies publiques pour matérialiser la séparation des voies de circulation, délimiter des voies piétonnes ou des zones de stationnement. Elles permettent, généralement, la séparation de zones sur le sol.We call edging here, the edging used on vehicle traffic lanes, especially on public roads to materialize the separation of traffic lanes, delimit pedestrian lanes or parking areas. They generally allow the separation of areas on the ground.

Elles sont par exemple utilisées pour délimiter les voies réservées aux transports publics, ou les voies affectées à l'un ou l'autre des sens de circulation.They are for example used to delimit the lanes reserved for public transport, or the lanes assigned to one or the other of the directions of circulation.

Il s'agit plus particulièrement des séparations formant un relief par rapport à la surface du sol. Ces bordurettes ne constituent pas un obstacle agressif, mais au contraire sont susceptibles d'être franchies, lorsque cela est fait à dessein, par un véhicule sans qu'il n'en résulte aucun dommage. Par contre, elles ne peuvent être franchies par inadvertance.These are more particularly the partitions forming a relief with respect to the surface of the ground. These curbs do not constitute an aggressive obstacle, but on the contrary are likely to be crossed, when this is done on purpose, by a vehicle without any resulting damage. However, they cannot be crossed inadvertently.

On connaît déjà un certain nombre de dispositifs qui permettent de réaliser de telles séparations.A number of devices are already known which make it possible to carry out such separations.

Certaines séparations ont été réalisées en béton. Elles nécessitent généralement la réalisation de fondations qui assurent le maintien et la stabilité des murets ainsi réalisés.Some partitions have been made in concrete. They generally require the creation of foundations which ensure the maintenance and stability of the walls thus produced.

D'autres dispositifs sont fixés dans le sol. Ils peuvent être en plastique, en caoutchouc et forment des séparations continues ou discontinues. Ces différents systèmes doivent être ancrés dans le sol, ils sont relativement coûteux et leur entretien soulève des problèmes difficiles à régler.Other devices are fixed in the ground. They can be plastic, rubber and form continuous or discontinuous separations. These various systems must be anchored in the ground, they are relatively expensive and their maintenance raises problems which are difficult to solve.

On a également mis en oeuvre des séparations réalisées avec des enrobés rapportés sur la chaussée, et le plus souvent réalisés manuellement. Il en résulte des séparations au profil aplati, irrégulier et peu stable dans le temps.Separations made with asphalt added to the roadway, and most often made manually, have also been used. This results in separations with a flattened, irregular and not very stable profile in the weather.

Le but de l'invention est donc de proposer des bordurettes ayant une bonne tenue, un aspect esthétique agréable et une bonne stabilité dans le temps.The object of the invention is therefore to propose edgings having good hold, a pleasant aesthetic appearance and good stability over time.

C'est un autre objectif de l'invention de proposer une bordurette, dont le coût soit relativement faible et dont l'entretien soit facile.It is another objective of the invention to propose a border, the cost of which is relatively low and the maintenance of which is easy.

C'est encore un autre objectif de l'invention de proposer une bordurette qui puisse être colorée et permettre ainsi un marquage visuel complémentaire de celui assuré par son relief.It is yet another objective of the invention to provide a border which can be colored and thus allow a visual marking complementary to that provided by its relief.

C'est encore un objectif de l'invention de proposer un procédé et un dispositif de réalisation de telles bordurettes.It is also an objective of the invention to propose a method and a device for producing such edgings.

A cet effet, l'invention concerne un dispositif de réalisation de bordurettes en enrobés.To this end, the invention relates to a device for producing asphalt edging.

Selon l'invention, ce dispositif comporte une trémie, un tunnel de moulage, un vibrocompacteur.According to the invention, this device comprises a hopper, a molding tunnel, a vibrocompactor.

La trémie assure l'alimentation du tunnel de moulage en enrobés, et le vibrocompacteur est relié au tunnel de moulage, dont il assure la vibration et la progression.The hopper supplies the molding tunnel with asphalt, and the vibrocompactor is connected to the molding tunnel, for which it provides vibration and progression.

Dans différents modes de réalisation préférés, l'invention comporte, selon toutes leurs combinaisons techniquement possibles, les caractéristiques suivantes :

  • La trémie comporte un socle de mise en forme formant un bourrelet d'enrobés qui alimente le tunnel de moulage.
  • Le bourrelet d'enrobés a approximativement la largeur de la bordurette, et sa hauteur est environ 1,5 fois celle de la bordurette ; le tunnel de moulage assure par compactage les dimensions définitives de la bordurette.
  • La trémie est reliée au tunnel de moulage par des liaisons élastiques.
  • La bordurette est mise en place dans une engravure ménagée dans le sol ; la trémie comporte des roues reposant, lors de son utilisation sur le sol, en dehors de l'engravure, et des guides destinés à entrer dans l'engravure et à guider le dispositif, par rapport à celle-ci, lors de sa progression.
  • Il comporte une rampe d'arrosage destinée à pulvériser un liquide sur le bourrelet d'enrobés entre le socle de mise en forme et le tunnel de moulage.
In different preferred embodiments, the invention comprises, according to all their technically possible combinations, the following characteristics:
  • The hopper has a shaping base forming a bead of asphalt which feeds the molding tunnel.
  • The asphalt bead is approximately the width of the edging, and its height is approximately 1.5 times that of the edging; the molding tunnel ensures by compaction the final dimensions of the edging.
  • The hopper is connected to the molding tunnel by elastic connections.
  • The edging is placed in an engraving made in the ground; the hopper has wheels resting, when in use on the ground, outside the engraving, and guides intended to enter the engraving and to guide the device, with respect to the latter, during its progression.
  • It includes a spray bar intended to spray a liquid on the asphalt bead between the shaping base and the molding tunnel.

L'invention concerne également un procédé de réalisation de bordurette en enrobés sur un sol, dans lequel on forme une engravure dans le sol, on forme un bourrelet d'enrobés dans l'engravure, on donne sa forme et ses dimensions définitives à la bordurette par compactage des enrobés par un tunnel de moulage vibrant et glissant.The invention also relates to a method for producing asphalt edging on a floor, in which an engraving in the ground is formed, a bead of asphalt is formed in the engraving, its shape and its final dimensions are given to the edging by compacting the asphalt through a vibrating and sliding molding tunnel.

Selon différents modes de réalisation préférés de ce procédé, le bourrelet d'enrobés est aspergé par un liquide avant l'action du tunnel de moulage.According to various preferred embodiments of this process, the bead of asphalt is sprayed with a liquid before the action of the molding tunnel.

Les extrémités de la bordurette font l'objet d'un traitement de finition leur donnant une forme de biseau.The ends of the edging are subject to a finishing treatment giving them a bevel shape.

La bordurette en enrobés de l'invention est destinée à assurer la matérialisation de la séparation de voies de circulation de véhicules sur le sol. Elle est ancrée dans une engravure formée dans le sol, et les dimensions de sa section droite sont constantes.The asphalt edging of the invention is intended to ensure the materialization of the separation of vehicle traffic lanes on the ground. It is anchored in an engraving formed in the ground, and the dimensions of its cross section are constant.

De manière préférée, les enrobés sont colorés et la section apparente de la bordurette est en arc de cercle.Preferably, the coated materials are colored and the visible section of the border is in an arc.

L'invention vise la réalisation de bordurette 1 dans une engravure 3 réalisée sur un sol 2, telle que représentée sur la Figure 2.The invention relates to the production of edging 1 in an engraving 3 made on a floor 2, as shown in FIG. 2.

Ces bordurettes sont réalisées en enrobés.These edgings are made of asphalt.

On entend ici par enrobés, un mélange principalement réalisé à partir de granulats et de liants bitumineux, et généralement destinés à la construction routière.The term “coated materials” is understood here to mean a mixture mainly produced from aggregates and bituminous binders, and generally intended for road construction.

L'enrobage peut être réalisé à chaud ou à froid.The coating can be carried out hot or cold.

Le bitume est un liant hydrocarboné issu de la distillation du pétrole, il peut éventuellement être utilisé avec des élastomères améliorant ses qualités rhéologiques.Bitumen is a hydrocarbon binder from the distillation of petroleum, it can optionally be used with elastomers improving its rheological qualities.

Les enrobés utilisés pour la réalisation des bordurettes de l'invention peuvent être avantageusement colorés, ce qui permet une meilleure visualisation des bordurettes, dont la couleur contraste avec la couleur de la chaussée.The coated materials used for the production of the curbs of the invention can be advantageously colored, which allows better visualization of the curbs, the color of which contrasts with the color of the roadway.

Le dispositif de réalisation de bordurettes en enrobés, représenté dans son ensemble sur la Figure 1, comporte une trémie 4, un tunnel de moulage 5 et un vibrocompacteur 6.The device for producing coated edgings, shown as a whole in FIG. 1, comprises a hopper 4, a molding tunnel 5 and a vibrocompactor 6.

La trémie 4 comporte une partie évasée destinée à recevoir les enrobés et une partie inférieure 7 comportant un socle de mise en forme 8.The hopper 4 comprises a flared part intended to receive the coated materials and a lower part 7 comprising a shaping base 8.

Cette trémie 4 repose sur le sol 2 de part ses roues 9, 10 et est guidée par les guides 11, 12 portés par sa base.This hopper 4 rests on the ground 2 due to its wheels 9, 10 and is guided by the guides 11, 12 carried by its base.

Le tunnel de moulage 5 est conformé de manière à se raccorder au socle de mise en forme 8. Il comporte une partie conique 13 et une zone cylindrique longitudinale 14.The molding tunnel 5 is shaped so as to connect to the shaping base 8. It has a conical part 13 and a longitudinal cylindrical zone 14.

Cette zone cylindrique 14 sert de moulage glissant à la bordurette 1, à laquelle il donne sa forme définitive. La zone conique 13 assure le raccordement entre le socle de mise en forme 8 et la zone cylindrique 14.This cylindrical zone 14 serves as a sliding molding at the border 1, to which it gives its final shape. The conical zone 13 provides the connection between the shaping base 8 and the cylindrical zone 14.

Le tunnel de moulage 5 comporte un plateau supérieur 15, une plaque de fixation 16 et des renforts 25.The molding tunnel 5 comprises an upper plate 15, a fixing plate 16 and reinforcements 25.

La plaque de fixation 16 du tunnel de moulage 5 est reliée à une plaque de fixation 17 de la trémie par l'intermédiaire des liaisons élastiques 18, 19. Ces liaisons élastiques 18, 19 peuvent, par exemple, être réalisées avec des blocs élastiques, ou "silent blocs", vissés à l'une de leurs extrémités à la plaque de fixation 16 du tunnel de moulage, et à l'autre extrémité à la plaque de fixation 17 de la trémie 4.The fixing plate 16 of the molding tunnel 5 is connected to a fixing plate 17 of the hopper via the elastic connections 18, 19. These elastic connections 18, 19 can, for example, be produced with elastic blocks, or "silent blocks", screwed at one of their ends to the fixing plate 16 of the molding tunnel, and at the other end to the fixing plate 17 of the hopper 4.

Le vibrocompacteur 6 comporte un ensemble moteur 20 et un réservoir 21. L'ensemble moteur 20 assure la vibration de la plaque vibrante 22. Le vibrocompacteur 6 est éventuellement équipé d'une poignée de manoeuvre 23.The vibrocompactor 6 comprises a motor assembly 20 and a reservoir 21. The motor assembly 20 ensures the vibration of the vibrating plate 22. The vibrocompactor 6 is optionally equipped with an operating handle 23.

Le vibrocompacteur 6 est fixé sur le plateau supérieur 15 du tunnel de moulage 5, par exemple par un ensemble de boulons.The vibrocompactor 6 is fixed on the upper plate 15 of the molding tunnel 5, for example by a set of bolts.

Ainsi, lors du fonctionnement du dispositif, le vibrocompacteur produit la vibration du tunnel de moulage et sa progression dans la direction de la trémie.Thus, during operation of the device, the vibrocompactor produces the vibration of the molding tunnel and its progression in the direction of the hopper.

Les liaisons élastiques 18, 19 amortissent les vibrations qui ne sont que très partiellement transmises à la trémie. Les vibrations transmises facilitent la descente des granulats.The elastic connections 18, 19 dampen the vibrations which are only very partially transmitted to the hopper. The vibrations transmitted facilitate the descent of the aggregates.

Une rampe d'arrosage 24 est avantageusement placée entre le tunnel de moulage 5 et la trémie 4. Elle est utilisée pour pulvériser un liquide sur le bourrelet d'enrobés après sa formation par le socle de mise en forme 8 de la trémie 4. Ce liquide est, par exemple, de l'eau savonneuse qui facilite le glissement du tunnel de moulage sur l'enrobé et évite tout risque d'adhésion de l'enrobé sur le tunnel.A spray bar 24 is advantageously placed between the molding tunnel 5 and the hopper 4. It is used to spray a liquid on the bead of asphalt after its formation by the shaping base 8 of the hopper 4. This liquid is, for example, soapy water which facilitates the sliding of the molding tunnel on the mix and avoids any risk of adhesion of the mix on the tunnel.

La rampe d'arrosage 24 peut être alimentée soit par un réservoir porté par le dispositif, soit à partir de tout réservoir extérieur.The spray bar 24 can be supplied either by a tank carried by the device, or from any external tank.

La réalisation de bordurettes 1 en enrobés est faite sur un sol, et de préférence une chaussée.The production of asphalt curbs 1 is made on a ground, and preferably a roadway.

On réalise tout d'abord une engravure 3 dans la chaussée par des moyens traditionnels bien connus de découpe.First an engraving 3 is made in the roadway by well-known traditional cutting means.

On forme alors un bourrelet d'enrobés dans l'engravure, par exemple par la trémie 4 et son socle de mise en forme 8, telle que décrit plus haut.A bead of coated material is then formed in the engraving, for example by the hopper 4 and its shaping base 8, as described above.

On donne alors sa forme et ses dimensions définitives à la bordurette 1 par compactage des enrobés par un tunnel de moulage vibrant et glissant, par exemple par l'ensemble tunnel de moulage 5 et vibrocompacteur 6, également décrit plus haut.Its shape and its final dimensions are then given to the edging 1 by compaction of the coated materials by a vibrating and sliding molding tunnel, for example by the molding tunnel 5 and vibrocompactor 6 assembly, also described above.

Afin d'éviter tout risque d'adhésion de l'enrobé au tunnel de moulage, il est préférable d'asperger le bourrelet d'enrobés par un liquide, par exemple une eau savonneuse, avant le passage du tunnel de moulage.In order to avoid any risk of adhesion of the mix to the molding tunnel, it is preferable to spray the bead of mixes with a liquid, for example soapy water, before the passage of the molding tunnel.

Ce procédé permet d'obtenir une bordurette continue, dont les dimensions de la section droite sont constantes. Afin de faciliter le franchissement des bordurettes et de diminuer leur caractère agressif, leurs extrémités peuvent faire l'objet d'un traitement de finition, éventuellement manuel, de manière à assurer le raccordement de leurs surfaces supérieures avec le sol, en forme de biseau.This process makes it possible to obtain a continuous edging, the dimensions of the cross section of which are constant. In order to facilitate the crossing of the edgings and to reduce their aggressive character, their ends can be the subject of a finishing treatment, possibly manual, so as to ensure the connection of their upper surfaces with the ground, in the form of a bevel.

La bordurette en enrobés de l'invention est destinée à assurer la matérialisation de la séparation de voies de circulation de véhicules sur le sol. Elle est ancrée dans une engravure 3 formée dans le sol 2 et les dimensions de sa section droite sont constantes. Elle est peut être réalisée en enrobés colorés. On obtient une bonne finition en utilisant des enrobés d'une granulométrie de l'ordre de 0,6 mm. Le liant utilisé est avantageusement un béton bitumineux, dont le liant est incolore.The asphalt edging of the invention is intended to ensure the materialization of the separation of vehicle traffic lanes on the ground. It is anchored in an engraving 3 formed in the ground 2 and the dimensions of its cross section are constant. It can be done in colored mixes. A good finish is obtained by using coated materials with a particle size of the order of 0.6 mm. The binder used is advantageously a concrete bituminous, the binder of which is colorless.

La couleur de la bordurette peut être donnée par le granulat. Il est également possible d'additionner un colorant au liant ou de peindre la bordurette.The border color can be given by the aggregate. It is also possible to add a dye to the binder or to paint the border.

On peut également incorporer au liant des matériaux réfléchissants, tels que des morceaux de verre ou des billes de verre.It is also possible to incorporate reflective materials, such as pieces of glass or glass beads, into the binder.

La section apparente et émergente de la chaussée de la bordurette est avantageusement en arc de cercle.The visible and emerging section of the pavement road is advantageously in an arc.

Lors de la mise en oeuvre du procédé, l'engravure 3 est tout d'abord réalisée dans le sol 2. La trémie repose alors sur le sol 2 par ses roues 9, 10 et est guidée par les guides 11, 12 qui sont placés dans l'engravure et s'appuient sur ses côtés.During the implementation of the method, the etching 3 is first carried out in the ground 2. The hopper then rests on the ground 2 by its wheels 9, 10 and is guided by the guides 11, 12 which are placed in the engraving and lean on its sides.

Les enrobés préparés sont introduits dans la trémie 4 qui, par l'effet des vibrations, s'écoulent jusqu'au fond de l'engravure 3. Le socle de mise en forme 8 réalise un bourrelet qui est ensuite compacté et mis à sa dimension définitive par le tunnel de moulage 5. Le vibrocompacteur 6 assure généralement la progression du dispositif, sans qu'il soit nécessaire de l'accompagner d'une action complémentaire.The prepared mixes are introduced into the hopper 4 which, by the effect of the vibrations, flows to the bottom of the groove 3. The shaping base 8 produces a bead which is then compacted and brought to its dimension final by the molding tunnel 5. The vibrocompactor 6 generally ensures the progression of the device, without it being necessary to accompany it with a complementary action.

Toutefois, la poignée de manoeuvre 23 peut être utilisée pour ralentir ou accélérer la progression du dispositif.However, the operating handle 23 can be used to slow or accelerate the progression of the device.

A titre indicatif, le dispositif décrit plus haut a permis de réaliser plus de 350 m de bordurettes en une durée de 8 h.As an indication, the device described above made it possible to make more than 350 m of curbs in a period of 8 h.

Cette bordurette a avantageusement une largeur de 40 cm et une hauteur au-dessus du niveau du sol de de l'ordre de 8 cm. La profondeur de l'engravure est de 5 cm.This edging advantageously has a width of 40 cm and a height above ground level of the order of 8 cm. The depth of the engraving is 5 cm.
