Grave Mousse® is a bituminous base course material made by spraying foamed bitumen on unheated materials. Grave Mousse ® is used in reinforcement and reprofiling as well as in new construction. Grave Mousse® can be stored for several days. It has good mechanical performance and is particularly resistant to rutting. The cold process can be made with local and recycled materials (household waste bottom ash, crushed concrete, etc.) and thus fosters sustainable development.
