Beschreibung
Zusammenfassung:	The present invention is directed to a process for preparing a binder for a warm mix asphalt composition. The binder comprises lignin, a renewable and bio-based material, which replaces part of the fossil-based bitumen when the components are used in preparing a warm mix asphalt, that comprises a reduced amount of wax, fatty acid amides, surfactants and emulsifiers. La présente invention concerne un procédé de préparation d'un liant pour une composition d'asphalte mélangé à chaud. Le liant comprend de la lignine, un matériau renouvelable d'origine biologique, qui remplace une partie du bitume d'origine fossile lorsque les composants sont utilisés dans la préparation d'un asphalte mélangé à chaud, qui comprend une quantité réduite de cire, d'amides d'acides gras, de tensioactifs et d'émulsifiants.
