Kraft lignin in asphalt

The main goal of the project is to scale-up binder production using kraft lignin (kraft lignin and bitumen) and by building a test road to study the characteristics of this innovative binder used in asphalt concrete. Kraft lignin is a commercial product from the forest industry.

The overall purpose of this project is to significantly reduce the use of fossil resources when building and maintaining roads. Fossil free transports is a common objective of contractors and the Swedish Transport Administration. Concerning asphalt production, the transition from fossil fuel has been rapid and next in turn is reducing fossil resources in the binder, and possibly, allowing for a temporary carbon sink.
