Abstract

La présente invention concerne un additif de liaison hybride organique-inorganique pour lier du béton de ciment et de l'asphalte. Lorsqu'il est utilisé dans une route comprenant une couche de béton de ciment et une couche d'asphalte construite sur la couche de béton de ciment, l'additif de liaison agit pour lier la couche de béton de ciment et la couche d'asphalte. L'additif de liaison comprend de 1 à 3 % en poids d'un acide organique, de 5 à 10 % en poids d'un sulfate, de 3 à 5 % en poids d'un sulfite, de 5 à 10 % en poids d'un carbonate, de 5 à 10 % en poids d'un phosphate, et le reste d'un chlorure. Selon la présente invention, l'additif de liaison peut être appliqué à la surface du béton de ciment servant de couche de base ou ajouté à une composition d'asphalte avant la construction de la couche d'asphalte, fixant ainsi fermement le béton de ciment et l'asphalte.
