Abstract

The invention relates to a device making it possible to create vibrations within the bulk of the highway materials during spreading in order to facilitate their compaction. The device, mounted onto conventional spreading machines or special machines, consists either of vibrating rods 1, or of a vibrating plate placed at the bottom or within the thickness of the layer of the swelled material to be spread. The device may be connected in certain cases to a plate 3 in order to facilitate the flow of the materials. The vibrations of 1, and optionally 3, enable the aggregates to be more efficiently arranged and facilitate the subsequent compaction by conventional means of the spread layer. The layers produced by this method have a low density gradient in relation to the thickness, resulting in a better mechanical performance and a longer service life.

REPANDAGE ET COMPACTAGE
La présente invention concerne un dispositif permettant de mieux réarranger les granulats des matériaux pour couches de chaussées (bases, fondation, formes,surface...)lors de leurs épandages pourfaciliter le précompaetage et le compactage ultérieur de ces matériaux.MASS VIBRATION DEVICE

SPREADING AND COMPACTION
The present invention relates to a device making it possible to better rearrange the aggregates of the materials for pavement layers (bases, foundation, shapes, surface, etc.) during their spreading in order to facilitate the pre-packing and subsequent compacting of these materials.

Nous entendons par matériaux de chaussées, tous les matériaux pour chaussées ou matériaux tels que graves, sables, sols fins traites par un liant quelconque(hydraulique , bitumineux,...) ou stabilisés mécaniquement. By pavement materials, we mean all pavement materials or materials such as gravel, sand, fine soil treated with any binder (hydraulic, bituminous, ...) or mechanically stabilized.

te répandage de ces matériaux, avant le compactage par les rouleaux à jantes lisses ou à pneumatiques,vibrant ou non, sont effectués traditionnellement à l'aide soit de la niveleuse, soit des machines à coffrages glissants,soit du finisseur,....  The spreading of these materials, before compaction by rollers with smooth or pneumatic rims, vibrating or not, are traditionally carried out using either the grader, or machines with sliding formwork, or the finisher, ...

Ces matériels, en général répandent et égalisent la surface du matériau foisonné; l'action des compacteurs vibrants ou non vibrants agissent uniquement par 11 effet de contact à la surface supérieure de la couche. These materials, in general spread and equalize the surface of the expanded material; the action of vibrating or non-vibrating compactors act only by the effect of contact on the upper surface of the layer.

Certains matérielsde répandage,(par exemple le finisseur ou l'autograde)lors de l'étalement du matérnaU,tentent d'arranger positionsdes granulats en les faisant vibrer par contact à la surface supérieure de la couche des matériaux avec,soit un coffrage vibrant,soit une table vibrante,soit une dame vibrante (fig l),ceci afin d'arranger les granulats entr'eux par vibration et faciliter ainsi le compactage ultérieur du matériau. Certain spreading materials (for example the paver or autograde) when spreading the material, try to arrange the positions of the aggregates by vibrating them by contact on the upper surface of the layer of materials with either a vibrating formwork, either a vibrating table, or a vibrating table (fig l), this in order to arrange the aggregates between them by vibration and thus facilitate the subsequent compaction of the material.

tes vibrations ainsi transmises aux granulats sont rapidement amorties par l'épaisseur du matériau et seuls les granulats près des surfaces vibrantes sont mis en place,arrangés et facile à compacter.Be matériau se trouvant au milieu ou en fond de couche est peu influencé par la vibration en surface, n'est donc pas ou peu arrangé ,ce qui rend le compactage difficile à ces niveaux. your vibrations thus transmitted to the aggregates are quickly absorbed by the thickness of the material and only the aggregates near the vibrating surfaces are put in place, arranged and easy to compact. The material being in the middle or at the bottom of the layer is little influenced by the vibration on the surface, is therefore not or little arranged, which makes compaction difficult at these levels.

On observe alors dans les couches de chaussées ainsi réalisées de forts gradients de densitéTes matériaux en surface sont bien compactés alors que ceux en fond de couche ne le sont que faiblement
te dispositif selon l'invention permet de remédier à cet inconvénient.We then observe in the pavement layers thus produced strong density gradients Your surface materials are well compacted while those at the bottom of the layer are only slightly
The device according to the invention overcomes this drawback.

te dispositif est caractérisé par des tiges ou des plaques effilées vibrantes(fig 2 et 3).Ces tiges ou plaques seront disposée soit au niveau de la base de la couche,soit dans l'épaisseur de la couche et avance en même temps que le matériel de répandage. The device is characterized by vibrating tapered rods or plates (fig 2 and 3). These rods or plates will be placed either at the base of the layer or in the thickness of the layer and advance at the same time as the spreading material.

te matériau répandu est ainsi vibré dans la masse,les granulats sont bien arrangés,le matériau est alors facile à compacter.The spread material is thus vibrated in the mass, the aggregates are well arranged, the material is then easy to compact.

te dispositif proposé peut entre monté sur toute machine de répandage actuel et peut fonctionner parallèlement ou non avec des tables,dames, ou compacteur vibrants. te proposed device can between mounted on any current spreading machine and can operate parallel or not with tables, checkers, or vibrating compactor.

Lorque l'épaisseur de la couche à répandre est suffisamment épais, l'utilisation de plusieurs systèmes de tiges à différents niveauxde la couche est quelquefois nécessaire. When the thickness of the layer to be spread is sufficiently thick, the use of several rod systems at different levels of the layer is sometimes necessary.

La longueur, la sectionet la forme ainsi que la distance entre les tiges doivent être contus suivant la nature du matériau. Il en est de même de la fréquence et du mode de vibration des tiges et des plaques. The length, cross-section and shape as well as the distance between the rods must be determined according to the nature of the material. The same applies to the frequency and the mode of vibration of the rods and plates.

Une variante consiste à monter les dispositifs 1 et 2 avec un dispositif 3 qui fait suite aux dispositifs Ocu Q2 .te dispositif o comportant une plaque horizontale ou inclinée vers les dispositifs 1 ou 2, vibrant ou non vibr nt,disposé au fond, à l'emplacement du déversement à l'arrivée des matériaux. Ce dispositif, tout en facilitant l'écoulement des matériaux participe à la vibration des matériaux. A variant consists in mounting the devices 1 and 2 with a device 3 which follows the Ocu Q2 devices. This device o comprising a horizontal or inclined plate towards the devices 1 or 2, vibrating or not vibrating, arranged at the bottom, at the location of spill on arrival of materials. This device, while facilitating the flow of materials participates in the vibration of materials.

Le matériau est ainsi vibré dans la masse et l'arrangement des granulats après le répandage est plus apte à un compactage: traditiounel(table vibrante, dame vibrante, compacteur...). The material is thus vibrated in the mass and the arrangement of the aggregates after spreading is more suitable for compacting: traditional (vibrating table, vibrating scraper, compactor ...).

Ce dispositif permet donc de vibrer le matériau dans toutte l'epaisseur de la couche,les granulats sont ainsi arrangés de façon plus homogène,le compactage sera plus aisé.Tes couches de chaussées ainsi réalisées sont plus homogènes en densité , la qualité de la chaussée est améliorée et sa durée de vie augmentée.  This device therefore makes it possible to vibrate the material throughout the thickness of the layer, the aggregates are thus arranged more homogeneously, compaction will be easier. Your pavement layers thus produced are more homogeneous in density, the quality of the pavement is improved and its lifespan increased.
