The invention concerns the continuous production of bituminous materials modified by addition of polymers and reacted with sulphur. The binders resulting from said method can contain very high amounts of polymers also combined with secondary materials such as: rubber, various plastics and waste lubricants. This type of binders, which cannot be obtained by discontinuous batch technology, results from the continuous mixing of several bituminous constituents through a static mixer. Said binders provide very high performance bituminous materials and agents for regenerating old bituminous materials contained in waste road materials, in the process of hot recycling of coated materials. They are also used for producing novel emulsions of highly modified binders, with multiple applications and in particular for cold recycling. This novel method, by regeneration of old bitumen contained in waste coated materials, represents a means for waste conversion and for limiting the use of bitumen and road surfacing aggregates.

Il s'agit d'un procédé de fabrication en continu de bitumes modifiés par ajout de polymères et réagis avec du soufre. Les liants issus de ce procédé peuvent contenir des quantités très importantes de polymères associées également à des matériaux de récupération tels que: caoutchouc, plastiques divers et lubrifiants usagés. Le mélange en continu de plusieurs constituants bitumineux, au travers d'un mélangeur statique, conduit à ce type de liants, d'obtention impossible avec la technologie discontinue par batch. Ils permettent l'obtention de matériaux bitumineux à très haut niveau de performances et d'agents de régénération des vieux bitumes contenus dans les matériaux usés de chaussées, dans le cadre du recyclage à chaud des enrobés. Ils contribuent également à l'obtention de nouvelles émulsions de liants très modifiés, d'applications multiples et en particulier pour le recyclage à froid. Ce nouveau procédé, par régénération des vieux bitumes contenus dans les enrobés usagés, représente un moyen de valorisation et de limitation d'emploi de bitume et d'agrégats de chaussées.
