Lignin-based bio-asphalt

, 2019
The present invention relates to a composition comprising bitumen; optionally vegetable oil or derivative thereof; and a lignin preparation, wherein the lignin preparation is characterized by a lignin purity of 60-100 wt.% with respect to the weight of the lignin preparation; and a lignin average molecular weight of 1000-5000 g/mol. The composition may
