Abstract

a) Layer in the form of a ground covering; b) characterised in that it comprises, in percentages by weight, between 80 and 99 % of byproducts extracted from mines or quarries as well as between 1 and 3 % of powdered quick lime, these components being mixed by implementing a mixing operation known per se. c) The invention relates to a layer in the form of a ground covering.

Description

"Couche de forme de chaussée".
La présente invention se rapporte à une couche de forme de chaussée, c'est-à-dire à une couche dont le rôle est d'isoler la couche de chaussée du contact de l'argile et d'améliorer la portance du sol. La couche de forme qui est la première constituante d'une route à partir d'un sol quelconque en est donc le support du point de vue portance et compactage."Pavement shape layer".
The present invention relates to a pavement form layer, that is to say a layer whose role is to isolate the pavement layer from contact with clay and improve the bearing capacity of the ground. The form layer which is the first constituent of a road from any ground is therefore the support from the point of view of lift and compaction.

Lors de l'exploitation de mines ou de carrières, les produits directement issus du front de taille sont généralement soumis à une opération de tri préliminaire, sur un appareil vibrant. Les résidus provenant de cette opération, nommés"scalpage"par les spécialistes sont considérés le plus souvent comme inuti lisables, aussi sont-ils dans leur majorité rassemblés et entreposés sur des terrils. During the exploitation of mines or quarries, the products directly coming from the working face are generally subjected to a preliminary sorting operation, on a vibrating device. The residues from this operation, called "scalping" by specialists are generally considered as useless, so they are mostly collected and stored on slag heaps.

Or, on s'est rendu compte, que de tels sous-produits, dont la granulométrie est généralement de dimension O/D, D étant compris entre 20 et 60 mm, sont relativement riches en éléments fins, et contiennent en fait suffisamment de particules argileuses pour permettre leur malaxage avec un liant. However, it has been realized that such by-products, the particle size of which is generally of O / D dimension, D being between 20 and 60 mm, are relatively rich in fine elements, and in fact contain sufficient particles. clay to allow their mixing with a binder.

La présente inventiona pour objet de tenir compte de cette propriété pour proposer un moyen permettant l'utilisation de ces résidus pour la fabrication de couches de forme de chaussée.  The object of the present invention is to take account of this property in order to propose a means allowing the use of these residues for the manufacture of pavement form layers.

A cet effet, l'invention a pour objet une couche de forme de chaussée caractérisée en ce qu'elle comporte en pourcentages pondéraux entre 80 et 99 X de sous-produits d'extraction de mines ou carrières, ainsi qu'entre 1 et 3 X de chaux vive en poudre, ces composants étant mélangés par la mise en oeuvre d'une opération de malaxage connue en elle-mme. To this end, the subject of the invention is a pavement-shaped layer, characterized in that it comprises in weight percentages between 80 and 99 X of by-products from mining or quarrying, as well as between 1 and 3 X of quicklime powder, these components being mixed by the implementation of a kneading operation known in itself.

Les couches ainsi obtenues, se sont montrées particulièrement satisfaisantes, de par leur rigidité et leur résistance aux intempéries, particulièrement au gel ; toutefois, leur avantage essentiel est lié à leur prix de revient particulièrement peu élevé, étant donné que leur constituant principal est un résidu toujours disponible de l'exploitation des mines ou carrières. The layers thus obtained have been shown to be particularly satisfactory, by their rigidity and their resistance to weathering, particularly to frost; however, their main advantage is linked to their particularly low cost price, given that their main constituent is an always available residue from the exploitation of mines or quarries.

Selon une autre caractéristique de l'inven- tion, la couche de forme de chaussée comporte entre 80 et 99 % de déchets calcaires résultant de l'exploitation de carrières. According to another characteristic of the invention, the pavement form layer comprises between 80 and 99% of limestone waste resulting from the exploitation of quarries.

Ces déchets sont le résultat d'une opération de tri des matériaux issus du front de taille avant le concassage de la roche massive elle-mme ; leur utilisation entraîne une augmentation notable des performances mécaniques des couches de forme de chaussées ainsi qu'une diminution de leur sensibilité au gel. This waste is the result of a sorting operation of materials from the working face before the crushing of the massive rock itself; their use results in a significant increase in the mechanical performance of pavement form layers as well as a decrease in their sensitivity to frost.

Selon une autre caractéristique de l'inven- tion, la chaux vive a une granulométrie comprise entre 0 et 0,2 mm. According to another characteristic of the invention, quicklime has a particle size between 0 and 0.2 mm.

Selon une autre caractéristique de l'inven- tion, la couche de forme de chaussée comporte entre 5 et 15 X de laitier granulé prébroyé.  According to another characteristic of the invention, the pavement layer comprises between 5 and 15% of pre-ground granulated slag.

Selon une autre caractéristique de l'inven- tion, la couche de forme de chaussée comporte entre 5 et 15 % de cendres volantes. According to another characteristic of the invention, the pavement form layer comprises between 5 and 15% of fly ash.

Selon une autre caractéristique de l'inven- tion, la couche de forme de chaussée comporte entre 1 et 3 % de ciment.  According to another characteristic of the invention, the pavement form layer comprises between 1 and 3% of cement.
