How well does this handle several freeze-thaw cycles per year?

The carbon aspect is great, but I love how this attempts to address the unstable ground problem. Here in Quebec due to cheaply made road foundation and harsh freeze-thaw cycles, at this time of the year the roads have almost more potholes than... road.

Thank you for this Question! In Norway, where we have stabilized more than 2,5 mill sqm of road, this is the problem we solve the most. Our Lignin is very strong, and more dynamic than our competitors binders, which means it doesn't crack in freeze-thaw cycles like other binders can. And as we crush rocks and get an even mass to mix the lignin into, we get a very good road to handle such cycles. And the pothole-problems almost don't exist.
