Composition with bitumen, plasticity modifiers, lignin, and optional components
A recently granted patent (Publication Number: US11898014B2) discloses a composition for asphalt applications, comprising bitumen, plasticity modifying agents, lignin, and optional additional components. The lignin used in the composition has a specific Lignin Ion Exchange Capacity (LIEC) of 0.4 mol/kg dry matter (DM) or less. The lignin is obtained through a process involving hydrothermal pretreatment of lignocellulosic biomass, followed by hydrolysis and fermentation steps. The composition aims to enhance the properties of asphalt for various construction and infrastructure projects.
The patent further details the process of obtaining lignin from soft lignocellulosic biomass without the addition of acid or base during pretreatment. The composition includes specific parameters for the hydrothermal pretreatment, hydrolysis, and fermentation steps, ensuring the quality and performance of the final product. Additionally, the composition may include further components such as aggregates, fillers, and active components like dispersing agents, surfactants, and viscosity modifiers. The resulting asphalt composition can be used for sealing layers or in various asphalt applications like mastic asphalt or rolled asphalt, offering improved performance and sustainability in construction projects.
