Abstract

The hard shoulder or other road lane, which is usually not subjected to traffic, comprises a draining main surfacing made of draining surfacing material or porous concrete; the said surfacing is covered by a secondary layer made of a material which is impervious to the residual matter, which material is intended to protect the said lane so that its main surfacing does not become clogged up by the residual matter which settles thereon.

Description

La présente invention est particulièrement relative aux bandes d'arrêt d'urgence, qui sont prévues, par exemple, sur les bords latéraux des routes à plusieurs voies ou autoroutes et de façon plus générale aux bandes de chaussée habituellement non soumises à la circulation des véhicules.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. .

Plus particulièrement encore, l'invention concerne les bandes de chaussée de ce type, qui sont réalisées en un revêtement drainant, tel qu'un enrobé drainant.More particularly still, the invention relates to pavement strips of this type, which are made of a draining coating, such as a draining asphalt.

Un enrobé drainant est un mélange granulats-bitume qui présente un pourcentage de vides généralement supérieur à 20%. Les enrobés drainants connaissent un fort développement en couche de roulement sur les routes à grande circulation, en particulier sur les autoroutes, les rocades urbaines, les liaisons d'aménagement complémentaire du réseau autoroutier.A draining mix is an aggregate-bitumen mixture that has a void percentage generally greater than 20%. Draining asphalts are experiencing strong development as a wearing course on high traffic roads, in particular on motorways, urban bypasses, and complementary development links of the motorway network.

L'intérêt d'un tel revêtement ouvert est triple. Il assure:

  • le confort et la sécurité de conduite par temps de pluie, en supprimant notamment les projections d'eau à l'arrière des véhicules et en améliorant la visibilité du marquage routier,
  • la réduction des bruits de roulement,
  • l'adhérence à forte vitesse.
The advantage of such an open coating is threefold. He rocks:
  • driving comfort and safety in rainy weather, in particular by eliminating water spray at the rear of vehicles and improving the visibility of road markings,
  • reducing road noise,
  • grip at high speed.

Lorsqu'une chaussée est revêtue en enrobés drainants, pour permettre l'écoulement transversal des eaux provenant des voies vers les exutoires, la bande d'arrêt d'urgence est aussi revêtue de la même manière.When a roadway is coated with draining asphalt, to allow the transverse flow of water from the tracks to the outlets, the emergency stop strip is also coated in the same way.

Après la mise en service, de nombreux matériaux allochtones (poussières atmosphériques, cigarettes, débris métalliques, gomme de pneumatique, résidus de traitement de la chaussée.....) se déposent sur la chaussée.After commissioning, numerous non-native materials (atmospheric dust, cigarettes, metallic debris, tire rubber, pavement treatment residues, etc.) are deposited on the pavement.

Ces résidus sont progressivement déplacés par le trafic notamment vers la bande d'arrêt d'urgence. Celle-ci n'étant pas ou très peu soumise à la circulation, les résidus qui s'y déposent, y restent, et, petit à petit, pénètrent par gravité dans le corps du revêtement drainant, venant ainsi colmater les vides efficaces.These residues are gradually displaced by traffic, particularly to the emergency lane. As this is not or very little subject to traffic, the residues which deposit there, remain there, and, little by little, penetrate by gravity in the body of the draining covering, thus clogging the effective voids.

Au bout d'un certain temps, les premiers centimètres de la bande d'arrêt d'urgence sont complètement obstrués. L'eau qui provient des voies de circulation ne peut plus s'évacuer et elle rejaillit en limite de la bande d'arrêt d'urgence. A ce jour, les tentatives mécaniques de traitement in situ, sans fraisage du revêtement colmaté, ont échoué. On peut citer, par exemple, l'utilisation de matériels de type balayeuse-aspiratrice qui sont maintenant reconnus pour leur intérêt préventif et non curatif. Par contre, l'utilisation de tels engins à proximité des flots de circulation de poids lourds est dangereuse.After a while, the first few centimeters of the emergency stop strip are completely blocked. The water coming from the traffic lanes can no longer be evacuated and it flows out at the edge of the emergency stop lane. To date, mechanical attempts at in situ treatment, without milling the clogged coating, have failed. We can cite, for example, the use of sweeper-vacuum cleaner type materials which are now recognized for their preventive and not curative interest. On the other hand, the use of such devices close to heavy traffic flows is dangerous.

La présente invention a pour objet d'apporter une solution plus efficace et plus sécurisante pour empêcher le colmatage superficiel des bandes d'arrêt d'urgence en enrobés drainants. Selon l'invention, on applique sur lesdites bandes une couche secondaire en un matériau dont la formulation répond exactement au cahier des charges fixé par les gestionnaires des voiries à grande circulation, en particulier:

  • pas de modification des qualités drainantes des enrobés de la bande d'arrêt d'urgence,
  • possibilité de circuler occasionnellement sur la bande d'arrêt d'urgence en toute sécurité (adhérence au support et rugosité de surface),
  • pas de diminution de la qualité structurelle de la bande d'arrêt d'urgence,
  • pas de surépaisseur préjudiciable à la sécurité des usagers.
The object of the present invention is to provide a more effective and safer solution for preventing the surface clogging of emergency stop strips in draining mixes. According to the invention, a secondary layer of a material is applied to said strips, the formulation of which exactly meets the specifications set by the managers of high traffic roads, in particular:
  • no modification of the drainage qualities of the asphalt mixes of the emergency stop strip,
  • possibility of occasionally traveling on the emergency lane in complete safety (adhesion to the support and surface roughness),
  • no reduction in the structural quality of the emergency lane,
  • no excess thickness detrimental to user safety.

La présente invention a donc pour objet une bande d'arrêt d'urgence ou autre bande de chaussée habituellement soumise à la circulation, comprenant un revêtement principal drainant en enrobé drainant ou béton poreux, caractérisée en ce que ledit revêtement est recouvert par une couche secondaire en un matériau étanche aux résidus d'une granulométrie reconstituée, destiné à protéger ladite bande contre le colmatage de son revêtement principal par les résidus qui s'y déposent.The subject of the present invention is therefore an emergency stop strip or other strip of roadway usually subject to traffic, comprising a main drainage covering in porous concrete or porous concrete, characterized in that said covering 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 are deposited there.

Avantageusement le matériau dans lequel est réalisée la couche secondaire est un coulis bitumineux à froid. Le coulis bitumineux de la couche secondaire peut comprendre un mélange de granulats d'une émulsion de bitume, d'eau d'apport et d'additifs régulateurs. Les granulats peuvent être d'une granulométrie reconstituée de calibre 0/4, 0/5 ou 0/6. Une émulsion de bitume peut être réalisée à partir d'un bitume de grade supérieur ou égal à 40/50, dont la teneur en bitume est supérieure à 55%. L'épaisseur de cette couche secondaire peut varier entre 0,4 et 1,5 cm environ. Les additifs régulateurs de prise peuvent comporter des épaississants, des rhéofluidifiants ou des viscosants, ou tout autre produit similaire.Advantageously, the material in which the secondary layer is made is a cold bituminous grout. The bituminous grout of the secondary layer can comprise a mixture of aggregates of a bitumen emulsion, filler water and regulatory additives. 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.

Les additifs régulateurs de prise peuvent également comprendre un accélérateur.The setting regulator additives may also include an accelerator.

De préférence, la couche de béton bitumineux, dont elle est recouverte au moins partiellement, est coulée à froid et possède la composition pondérale ci-après:

- granulats
100%
- émulsion de bitume
12 à 14% du poids sec de granulats
- eau de mouillage
8 à 15% du poids de granulats
- épaississant
0,1 à 1,5% par rapport au poids de l'émulsion
- accélérateur
0,1 à 1,5% en poids sec de granulats
Preferably, the layer of bituminous concrete, with which it is at least partially covered, is cold cast and has the following composition by weight:
- aggregates
100%
- bitumen emulsion
12 to 14% of the dry weight of aggregates
- dampening water
8 to 15% of the weight of aggregates
- thickener
0.1 to 1.5% based on the weight of the emulsion
- accelerator
0.1 to 1.5% by dry weight of aggregates

La couche secondaire est avantageusement appliquée avec une densité de 12 à 20 kg/m².The secondary layer is advantageously applied with a density of 12 to 20 kg / m².

Egalement encore, le matériau dans lequel est réalisée la couche secondaire peut être un béton bitumineux coulé à chaud ou un sable enrobé ou une moquette routière.Also again, the material in which the secondary layer is made can be hot-poured bituminous concrete or coated sand or road carpet.

La hauteur entre la surface supérieure de la couche secondaire et la surface supérieure du revêtement de la partie circulante est préférentiellement inférieure à 1 cm.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.

La surface de la couche secondaire peut être au même niveau sur la surface du revêtement de la partie circulée de la chaussée.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.

L'invention a encore pour objet l'utilisation d'un coulis bitumineux à froid pour réaliser, sur une bande d'arrêt d'urgence ou toute autre bande non habituellement soumise à la circulation d'une chaussée en un revêtement drainant, une couche de protection contre le colmatage par les résidus qui s'y déposent.The subject of the invention is also the use of a cold bituminous grout to produce, on an emergency stop strip or any other strip not usually subjected to the movement of a roadway, a layer protection against clogging by residues deposited there.

La description qui suit de plusieurs modes de réalisation de l'invention est purement illustrative et non limitative.The following description of several embodiments of the invention is purely illustrative and not limiting.

Le revêtement routier de base mis en oeuvre selon l'invention est réalisé de façon classique en un enrobé drainant ou un béton poreux. La composition d'un tel enrobé drainant ou béton poreux est parfaitement connue de l'homme du métier. Il en est de même pour les moyens à mettre en oeuvre pour la réalisation de chaussées à partir de ces matériaux. On peut se référer à cet égard à la note d'informations de la SETRA en date du 13 Décembre 1990.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. One can refer in this respect to the information note of SETRA dated December 13, 1990.

Selon l'invention, la bande d'arrêt d'urgence réalisée à partir d'un tel revêtement drainant, est revêtue d'une couche secondaire de béton bitumineux coulé. Ce béton bitumineux coulé peut être un mortier bitumineux coulé à chaud, notamment à base de bitume polymère, ou un coulis bitumineux à froid.According to the invention, the emergency stop strip made from such a draining coating is coated with a secondary layer of poured bituminous concrete. This poured bituminous concrete can be a hot-poured bituminous mortar, in particular based on polymer bitumen, or a cold bituminous grout.

La composition d'un mortier bitumineux coulé à chaud est par exemple:

- gravillons concassés
10%
- sable
60%
- filler
30%
- bitume polymère
15%
The composition of a hot-poured bituminous mortar is for example:
- crushed gravel
10%
- sand
60%
- filler
30%
- polymer bitumen
15%

On utilise néanmoins préférentiellement un coulis bitumineux à froid. Un tel coulis bitumineux à froid est un mélange homogène de sable fillérisé, de gravillons, d'émulsion, d'eau et d'additifs régulateurs de prise.However, preferably a cold bituminous grout is used. Such a cold bituminous grout is a homogeneous mixture of fillerized sand, gravel, emulsion, water and additive regulators.

Il est appliqué en couche mince de 12 à 20 kg/m². Le dosage choisi est fonction du calibre retenu et du trafic.It is applied in a thin layer of 12 to 20 kg / m². The dosage chosen depends on the size selected and the traffic.

Un exemple de composition pondérale est le suivant:

- granulats
100% de matériaux secs
- émulsion
13% par rapport au poids sec de granulats
- eau de mouillage
10% par rapport au poids sec de granulats
- épaississant
1% par rapport à l'émulsion
- accélérateur
0,5% par rapport au granulats
An example of weight composition is as follows:
- aggregates
100% dry materials
- emulsion
13% based on the dry weight of aggregates
- dampening water
10% based on the dry weight of aggregates
- thickener
1% compared to the emulsion
- accelerator
0.5% compared to aggregates

On introduit successivement d'abord les granulats, puis l'eau d'apport et enfin l'émulsion. Les ajouts minéraux se font dans les granulats et les ajouts liquides dans l'eau d'apport.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.

Un tel produit d'étanchéité présente une pénétration limitée dans l'enrobé drainant (5 mm). Son état de surface appliquée est assez rugueux. Ce produit de colmatage présente en outre une bonne adhésion au support.Such a sealant has limited penetration into the draining asphalt (5 mm). Its applied surface finish is quite rough. This sealing product also has good adhesion to the support.

Dans d'autres exemples encore, le dosage de l'émulsion varie entre 12 et 14% en poids sec de granulats, l'eau de mouillage varie entre 8 à 15% en poids sec de granulats, l'accélérateur de prise varie de 0,1 à 1,5% en poids sec de granulats, l'épaississant entre 0,1 et 1,5% en poids d'émulsion.In still other examples, 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.

Cet épaississant est essentiellement sous forme liquide. Il est destiné à figer le coulis mais n'épaissit pas l'émulsion. Il s'ajoute soit dans l'eau d'apport soit dans l'émulsion. On pourra également avantageusement utiliser pour le remplacer des rhéofluidifiants ou des viscosants.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.

L'émulsion peut être de plusieurs types. Elle peut être une émulsion de bitume réalisée à partir d'un bitume 80/100 à teneur supérieure à 60%. Elle peut être également une émulsion élastomère obtenue par l'incorporation d'un latex dans la phase aqueuse de l'émulsion.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.

L'accélérateur peut être sous forme solide (ciment, chaux éteinte, chaux vive) ou sous forme liquide.The accelerator can be in solid form (cement, slaked lime, quicklime) or in liquid form.

Les granulats reconstitués sont préférentiellement de calibre 0/4, 0/5 ou 0/6. Pour un coulis bitumineux 0/4, les composants granulométriques seront compris entre 95% et 100% à 4 mm, 35% à 40% à 2 mm et 6% à 9% pour 0,08 mm.The reconstituted aggregates are preferably of size 0/4, 0/5 or 0/6. For a 0/4 bituminous grout, 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.

Le coulis est mis en oeuvre au moyen d'une machine spécifique compacte qui comprend les trémies à granulats, la cuve à émulsion, les cuves à eau et additifs divers, un malaxeur continu et le traîneau applicateur.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.

La couche secondaire de la bande d'arrêt d'urgence pourra être également réalisée en un sable enrobé 0/3, 0/4, 0/5 ou 0/6 avec ou sans liant en élastomère.The secondary layer of the emergency stop strip may also be made of 0/3, 0/4, 0/5 or 0/6 coated sand with or without an elastomer binder.

Pour le rendre plus rugueux dans son aspect de surface ou peut procéder à un cloutage de celui-ci.To make it rougher in its surface appearance or can make a studding of it.

L'application de ce sable enrobé se fait avec un matériel d'application routier classique. Après son application, il peut être compacté avec un cylindre lisse.The application of this coated sand is done with conventional road application equipment. After its application, it can be compacted with a smooth cylinder.

Egalement, la couche secondaire pourra être une moquette routière se collant directement sur le revêtement principal.Also, the secondary layer could be a road carpet sticking directly to the main covering.
