Patent

CA 2446901

The present invention provides a novel method to produce grade road base material using recycled oilfield waste, called "oil and gas waste," and aggregate waste and a novel road base material. Hydration and mixing of the waste materials along with a binder, will achieve an irreversible pozzolanic chemical reaction necessary for stabilization into a road base. An asphalt emulsifier may be included in the binder to manufacture asphalt stabilized road base. The entire method is a cold batch process.

L'invention concerne un nouveau procédé de production d'un matériau de couche de base pour route de qualité, à l'aide de déchets de gisements pétrolifères recyclés appelés "déchets pétrolifères et gazeux" et de déchets agrégats, ainsi qu'un nouveau matériau de couche de base pour route. Ce procédé consiste à hydrater et mélanger les déchets avec un agent liant, afin d'obtenir une réaction chimique pouzzolanique irréversible nécessaire à la stabilisation en une couche de base pour route. Un agent émulsifiant d'asphalte peut être compris dans l'agent liant afin de fabriquer une couche de base pour route stabilisée d'asphalte. Le procédé dans son entier est un processus discontinu à froid.
