Abstract

Device enabling to spread and vibrate road materials in the mass during the spreading thereof to facilitate compaction. The device may be mounted either on conventional machines or on self-propelled specially designed chassis, and it may be comprised of a vibrating box formed of a curved plate (1) and of two sidewalls (2). The bottom part of (1) in contact with the ground on which the material is to be spread must be flexible to conform to the deffects of the ground evenness. The component of the vibration of (1) is substantially contained within the horizontal plane. The material is tipped on the upper part of the box. The vibration of the box causes the material to go down to the spread layer, arranges the granulates before the setting thereof on the ground. This precompaction facilitates a further compaction of the material by conventional means. The device enables to alleviate the conventional compaction works and consequently reduce costs. Road layers thus built are therefore more compact and more homogeneous in density. The quality of the smoothness and the mechanical characteristics of the road are improved.

Description

Dispositif de vibration dans la masse des matériaux de chaussées lors de leurs répandage et compactage.Vibration device in the mass of pavement materials during their spreading and compaction.
La présente invention concerne un dispositif permettant de mieux réarranger les granulats des matériaux pour couches de chaussées (bases, fondation, formes, surface ....), lors de leur répandage, les précompacter pour faciliter le compactage de ces matériaux.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.), when they are spread, precompact them to facilitate the compacting of these materials.
Nous entendons par matériaux de chaussées, tous les matériaux constituant les chaussées tels que les graves , les sables, les sols fins, mélangés avec un liant quelconque (hydraulique ou bitumineux ) ou sans liant, avec eau ou sans eau, ou stabilisés mécaniquement.By pavement materials, we mean all the materials constituting pavements such as gravel, sand, fine soil, mixed with any binder (hydraulic or bituminous) or without binder, with water or without water, or mechanically stabilized.
Le répandage de ces matériaux,avant le compactage par des rouleaux à jantes lisses ou à pneumatiques, vibrant ou non, est effectué traditionnellement à l'aide soit de niveleuses, soit de machines à coffrages glissants, soit de finisseurs.....The spreading of these materials, before compacting by rollers with smooth or pneumatic rims, vibrating or not, is traditionally carried out using either graders, or machines with sliding formwork, or finishers .....
Certains matériels de répandage, par exemple le finisseur ou l'autograde, lors de l'étalement du matériau , tentent d'arranger les granulats entre-eux, créant ainsi un précompactage en faisant vibrer par contact à la surface supérieure de la couche des matériaux avec, soit un coffrage vibrant, soit une table vibrante.. (fig 1).Some spreading materials, for example the paver or autograde, when spreading the material, try to arrange the aggregates together, thus creating a precompaction by vibrating by contact on the upper surface of the layer of materials with either a vibrating formwork or a vibrating table .. (fig 1).
(7) représente les semelles ou dames vibrantes, (8)la vis de répartition, (9) le coffrage vibrant, (10) la couche de matériau répandue. Les vibrations ansi 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 faciles à compacter. Les granulats se trouvant en milieu ou en fond de couche, peu influencés par la vibration en surface ne sont donc pas ou peu arrangés, ceci rend le compactage ultérieur difficile à ces niveaux. Les matériaux en surface sont bien compac tés alors que ceux en fond de couche ne le sont que faiblement. On observe alors dans les couches de chaussées ainsi réalisées de forts gradients de densité qui qui font diminuer les performances du matériau et. de la structure.(7) represents the vibrating soles or ladies, (8) the distribution screw, (9) the vibrating formwork, (10) the layer of material spread. The 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 aggregates being in the middle or at the bottom of the layer, little influenced by the vibration on the surface are therefore not or little arranged, this makes subsequent compaction difficult at these levels. The surface materials are well compacted tees while those at the bottom of the layer are only weakly so. We then observe in the pavement layers thus produced strong density gradients which reduce the performance of the material and. of the structure.
Le dispositif selon l'invention permet de remédier à cet inconvénient,The device according to the invention overcomes this drawback,
Les figures 2 et 3 représentent respectivement la perspective et la coupe de la présente invention, Le dispositif se compose d'un caisson métallique vibrant ayant un fond formé d'une plaque courbe (1) et de deux parois latérales (2) .Le caisson n'est pas fermé à sa partie supérieure ainsi que le côté du matériau du matériau répandu. Le caisson est vibré à sa base par des vibrateurs (3) .La partie basse du caisson en contact avec la surface du sol sur lequel le matériau doit être répandu doit être souple afin d'épouser les défauts de planéité du sol. Elle peut être réalisée par exemple, soit à l'aide de membranes souples (4) en caouchouc ou autre matériau souple fixées au caisson (fig 4), soit que le fond de (1) se termine par des lames (5) découpées sur la tôle de (1) (fig 5).Figures 2 and 3 respectively represent the perspective and the section of the present invention, The device consists of a vibrating metal box having a bottom formed by a curved plate (1) and two side walls (2). is not closed at its top as well as the material side of the spilled material. The box is vibrated at its base by vibrators (3). The lower part of the box in contact with the surface of the ground on which the material is to be spread must be flexible in order to match the unevenness of the ground. It can be carried out, for example, either using flexible membranes (4) made of rubber or other flexible material fixed to the box (fig 4), or the bottom of (1) ends in blades (5) cut on the sheet of (1) (fig 5).
Le caisson est fermé partiellement du côté du matériau répandu par un système quelconque permettant de régler l'épaisseur du matériau répandu. Ceci peut être constitué par exemple par une lame vibrante (βj réglable en hauteur suivant le profil désiré de la couche répandue et indépendamment du caisson ou un système de tambour cannelé tournant, A l'endroit de la sortie de la couche répandue,les parois (2) peuvent avoir une forme qui permet de mouler directement les parois latérales de la couche du du matériau répandu. Pour y faciliter l'écoulement du matériau répandu, des vibrateurs peuvent être montés à cet emplacement.The box is partially closed on the side of the spilled material by any system allowing the thickness of the spilled material to be adjusted. This can be constituted for example by a vibrating blade (βj adjustable in height according to the desired profile of the spread layer and independently of the box or a rotating grooved drum system, At the place of the exit of the spread layer, the walls ( 2) may have a shape which allows the lateral walls of the layer of the spilled material to be molded directly. To facilitate the flow of the spilled material, vibrators can be mounted at this location.
La vibration principale du caisson est réalisée à l ' aide des vibrateurs (3) montés sur une poutre horizontale soudée au fond de (1) .Les vibrateurs sont montés de façon à imposer au caisson une vibration essentielle - ment contenue dans le plan horizontal parallèle à la surface du matériau répandu, la composante verticale de la vibration est quasi nulle ou négligeable vis à vis de l'amplitude de la vibration horizontale. Ceci peut être par exemple obtenu en disposant verticalement les axes des vibrateurs à balourds. Si la puissance des vibrateurs est insuffisante, on peut rajouter dans ce cas d'autres rangées de vibrateurs parallèles à la première rangée. Le dispositif peut être monté, soit sur un chariot automoteur, soit sur un des systèmes de répandage traditionnels. Le sens de déplacement du système est indiqué par la flèche de la figure 2 ,The main vibration of the box is carried out using vibrators (3) mounted on a horizontal beam welded to the bottom of (1). The vibrators are mounted so as to impose on the box a vibration essentially contained in the parallel horizontal plane. at the surface of the spilled material, the vertical component of the vibration is almost zero or negligible with respect to the amplitude of the horizontal vibration. This can for example be obtained by vertically arranging the axes of the imbalance vibrators. If the power of the vibrators is insufficient, we can add in this case other rows of vibrators parallel to the first row. The device can be mounted either on a self-propelled cart or on one of the traditional spreading systems. The direction of movement of the system is indicated by the arrow in Figure 2,
Le matériau est déversé dans le caisson à sa partie supérieure. La vibration de (1) et (2) par (3) et l'avancement du dispositif fait descendre le matériau vers la couche répandue,arrange les granulats dans tout l'épaisseur de la couche et précompacte le matériau , ce-ci facilite le compactage ultérieur par les moyens traditionnels (tables vibrantes, semelles vibrantes ou compacteurs vibrantes ou à pneumatiques). Sur la fig 3 est représenté un exemple de compactage par semelles ou dames vibrantes (7). (11) représente le chargement du matériau. L'usage de ce dispositif permet d'alléger l'atelier de compactage traditionnel, et en conséquence diminuer le prix de revient de la mise en oeuvre. Les matériaux des couches de chaussées ainsi réalisés sont plus compactes et plus homogène en densité, La qualité de l'uni et les performances mécaniques de la chaussée sont améliorées. The material is poured into the box at its top. The vibration of (1) and (2) by (3) and the advancement of the device brings the material down to the spread layer, arranges the aggregates throughout the thickness of the layer and precompacts the material, this facilitates the subsequent compaction by traditional means (vibrating tables, vibrating plates or vibrating or pneumatic compactors). In FIG. 3 is shown an example of compacting by vibrating soles or checkers (7). (11) represents the loading of the material. The use of this device makes it possible to lighten the traditional compaction workshop, and consequently reduce the cost price of the implementation. The materials of the pavement layers thus produced are more compact and more homogeneous in density. The quality of the level and the mechanical performance of the pavement are improved.
