Abstract

La présente invention a pour objet, dans un dispositif servant à constituer et à consolider des terrains, notamment des routes, au moyen de matériaux constitués de roche fractionnée, de gravillons, ou matériaux analogues, de rendre lesdits terrains carrossables en toute sécurité et de leur conférer une longévité importante. A cet effet, sont utilisés une sous-structure (2) fixée au sol, constituée de matériaux de type graviers, et une première et une seconde couche de remblai (3, 6) en matériaux de type graviers, laminées en couches superposées sur la sous-structure (2), pouvant être produites sur le chantier, et comportant de l'agglomérant bitumineux ajouté ainsi qu'un élément de renfort (4) en métal ou en matière plastique ou duroplastique, en forme de grille, disposé entre les deux couches de remblai (3, 6), un revêtement qui recouvre la couche de remblai bitumineuse supérieure (6) et qui est constitué d'asphalte, de bitume dur ou de béton, servant de couche de circulation (7).
