Patent

CA 2449710

A method of paving a gravel and/or dirt roadway (10) is provided. This method includes evaluating the roadway to determine if it is an appropriate candidate for emulsion stabilization, rotating a milling head (20) down a roadway to break up gravel and dirt base layer (14), injecting an asphalt emulsion into the broken up gravel and dirt (24), and mixing the emulsion with the gravel and dirt (24) so as to form an emulsion stabilized layer (18). The emulsion stabilized layer (18) is then spread and compacted to create a paved roadway. Following this, a wearing surface may be applied to the emulsion stabilized layer (18).

L'invention concerne un procédé de bitumage d'une route en gravier et/ou en terre (10). Ce procédé consiste à étudier la route pour déterminer si elle peut être stabilisée avec une émulsion, à faire tourner une fraiseuse (20) sur la route pour casser la couche de base de gravier et de terre (14), à injecter une émulsion de bitume dans le gravier et la terre cassés (24) et à mélanger l'émulsion avec le gravier et la terre (24) pour former une couche stabilisée avec l'émulsion (18). La couche stabilisée avec l'émulsion (18) est ensuite étalée et compactée pour obtenir une route revêtue. Une surface de roulement est ensuite appliquée sur la couche stabilisée avec l'émulsion (18).
