Claim 1:
2. A composition comprising bitumen, one or more plasticity modifying agent(s), lignin, and optionally one or more further component(s); wherein said lignin is obtained by a process for treatment of a lignocellulosic biomass, said process comprising:
a) subjecting lignocellulosic biomass to hydrothermal pretreatment resulting in a hydrothermally pretreated lignocellulosic biomass;
b) following step (a), subjecting at least part of said hydrothermally pretreated lignocellulosic biomass obtained in step (a) to a hydrolysis resulting in a liquid fraction comprising soluble carbohydrates, and a fiber fraction comprising a lignin component, wherein said hydrolysis is an acid catalyzed hydrolysis and/or enzymatic hydrolysis;
c) optionally, following step (b), subjecting at least part of the liquid fraction obtained in step (b) to a fermentation in order to ferment at least part of said soluble carbohydrates to a fermentation product, thereby obtaining a fermentation broth,
wherein said lignin has a Lignin Ion Exchange Capacity (LIEC) of 0.4 mol/kg dry matter (DM) or less.
