Abstract

The present invention is directed to a process for preparing a binder for an asphalt composition. The binder comprises lignin, a renewable and bio-based material, which replaces part of the fossil-based bitumen.

Claims (2)

Claims
1. A process for preparing an asphalt composition or a binder for an asphalt composition, comprising the steps of a) providing a lignin material having a solid content of lignin in the range of from 50 wt-% to 75 wt-%, calculated based on the total weight of the material; b) reducing the overall particle size of the lignin material of step a) by means of crushing, milling or disintegration; and c) mixing the lignin from step b) with a bitumen blend to obtain a binder for an asphalt composition or mixing the lignin from step b) with an asphalt blend to obtain an asphalt composition.
2. The process according to claim 1, wherein the lignin has been subjected to sieving before or after step b).
