Abstract

Covering consists of a base layer (a) contg. by wt. 10-50, esp. 10-20% clay soil; 1-10% slaked lime fixed to the clay; 10-30, esp. 10-20% coarse sand; and 30-80, esp. 60-80% of a coarse grained aggregate of pozzuolana, schist, clinker or slag. Layer(a) is covered by an intermediate layer(b) with the same compsn. as layer(a) except that the aggregate has a smaller grain size. On top of layer (b) is a surface layer of baked powdered clay or brick dust mixed with a small amt. of slaked lime. Layer(c) is not essential. In an example, layers(a,b) each contained 15% clay soil, 10% sand, and 75% pozzuolalana with grain size 5/20 in layer(a) and size 0/2 in layer(b). Layer(a) also contained 4.5 pts.wt. slaked lime, and layer(b) 6 pts.wt. slaked lime.

Description

ta presente invention a trait au domaine des revêtements de terrains, notamment de jeux et/ou sports. Elle concerne tout specialement des perfectionnements aux compositions pour couches de revêtements, décrites dans la demande de brevet principal. your present invention relates to the field of ground covering, in particular of games and / or sports. It especially relates to improvements to the compositions for coating layers, described in the main patent application.

On a décrit dans le brevet principal des revêtements constitues par la superposition, depuis la structure de fondation naturelle ou specialement préparee du sol : a) d'une couche de base comprenant un mélange, fixé à la chaux éteinte, de terre argileuse, de sable et d'une charge de forte granulometrie de type pouzzolane ou analogue ; b) d'une couche intermédiaire de même composition que ci-dessus mais avec une plus faible granulometrie de charge ; et c) d'une couche superficielle riche en argile cuite pulvérulente ou brique pilée et contenant une proportion mineure de chaux éteinte. In the main patent, coatings constituted by the superimposition, from the natural or specially prepared foundation structure of the soil, have been described: a) a base layer comprising a mixture, fixed with slaked lime, of clay soil, of sand and a filler of large particle size of pozzolan type or the like; b) an intermediate layer of the same composition as above but with a smaller particle size; and c) a surface layer rich in powdered baked clay or crushed brick and containing a minor proportion of slaked lime.

En pratique, les couches a) et b) renfermaient, pour 100 parties en poids de composition totale, 20 a 50 parties de terre argileuse, 10 a 30 parties de gros sable, 30 à 60 Parties de la charge et 2 a 6 parties de chaux. In practice, layers a) and b) contained, per 100 parts by weight of total composition, 20 to 50 parts of clay soil, 10 to 30 parts of coarse sand, 30 to 60 parts of the load and 2 to 6 parts of lime.

Les résultats obtenus avec de telles compositions sont rês bons notamment en ce qui concerne la résistance mécanique et la stabilité aux phénomènes habituels de retrait et gonflement. The results obtained with such compositions are very good, in particular as regards the mechanical strength and the stability to the usual phenomena of shrinkage and swelling.

Il a maintenant été trouvé que l'on pouvait obtenir des résultats aussi bons, sinon meilleurs dans certains cas, en faisant varier quelque peu, hors des gammes précitées, les proportions de certains constituants selon l'invention. It has now been found that it is possible to obtain results which are as good, if not better in certain cases, by varying somewhat, outside the above ranges, the proportions of certain constituents according to the invention.

Ainsi, la quantité de terre argileuse mise en oeuvre pour la réalisation des couches de base et intermédiaire peut être inférieure a 20 parties en poids et se trouver comprise entre les limites de 10 a 50 parties, généralement 10 a 40 parties, pour 100 parties (poids) de chaque couche précitée. En outre, il a été constaté que la limite supérieure du poids de charge telle que pouzzolane, mâchefer ou schiste pouvait monter a au moins 80 parties (poids) au lieu de 60 parties. Enfin, la quantité de chaux éteinte dans les deux couches a) et b) varie avantageusement entre 1 et 10 parties en poids et non 2 à 6 parties du poids total des autres constituants de chaque couche. Thus, the quantity of clay soil used for the production of the base and intermediate layers can be less than 20 parts by weight and be between the limits of 10 to 50 parts, generally 10 to 40 parts, per 100 parts ( weight) of each aforementioned layer. In addition, it was found that the upper limit of the load weight such as pozzolan, clinker or shale could rise to at least 80 parts (weight) instead of 60 parts. Finally, the quantity of slaked lime in the two layers a) and b) advantageously varies between 1 and 10 parts by weight and not 2 to 6 parts of the total weight of the other constituents of each layer.

A titre d'exemple non limitatif, on a réalisé sur sol naturel stable un revêtement obtenu de la façon suivante (% en poids) - une première couche de base, d'épaisseur 20 a 50mm après compactage, constituée de
terre argileuse contenant plus de 40 % d'argile
d'indice de plasticité au moins égal à 17 et de limite de liquidité au moins égal à 40 .............
By way of nonlimiting example, a coating obtained as follows (% by weight) was produced on stable natural soil - a first base layer, of thickness 20 to 50 mm after compaction, consisting of
clay soil containing more than 40% clay
plasticity index at least equal to 17 and liquidity limit at least equal to 40 .............
