Abstract

L'invention concerne un procédé pour la fabrication 'in situ' d'un pavage continu qui consiste en un volume d'agrégats (2) de taille et de forme variable imprégné de résine, laquelle définit avec lesdits agrégats des espaces intérieurs reliés entre eux que l'on remplit d'une pâte de mortier hydraulique qui compacte ledit volume dans au moins une hauteur à partir de la surface libre, laquelle est mécanisée au moyen d'un poli spéculaire. Dans un autre mode de réalisation, on peut également ajouter aux agrégats ou granulats, soit des résines au moyen de dispositifs appropriés ou par gravité, ce qui permet d'obtenir un corps rigide tabulaire, rabaissé au niveau de sa surface, présentant une zone plate remplie d'une résine époxy ou analogues, soit n'importe quel matériau hydraulique, ce qui permet d'y ajouter des colorants.
